Q&A Log


09:44:15 PDT

Question: can you deliver a sip trunk from an itsp directly to a branch location, which has an sba\sbs in it

and if so what would be the requirements to have that implementation supported? i.e. sba with sbc

integrated \ separate mediation server etc?

Answer: Being answered live by Brian!

09:45:32 PDT

Question: Would like you to advise at some point on the best LYNC 2013 option for setting up a remote

office that only has an internet connection for LYNC, not a dedicated WAN pipe. How do you maintain a

quality LYNC experience at an internet only connected site or can you ?

Answer: Answered Live

09:45:42 PDT

Question: do you still have to separate out the mediation server role if the sip trunk from the itsp is

delivered via an on-premise sbc?

Answer: Replied Live

09:48:00 PDT

Question: Is there a fully hosted Lync 2013 solution around Office 365 Lync and some VOIP hoisting

provider that provides most of the Lync voice capabilities and Lync Office 365 Exchange integration to

small business for a small number of users and a small cost per month that avoids a hardware investment

other than possibly a few Polycom VOIP phones?

Answer: HI Bill - there are various companies that host Lync 2013 and Exchange 2013 offering a various

level of services. Keep in mind that this does not include O365 today as full enterprise voice in the cloud is

not available from O365

09:58:36 PDT

Question: Will it be shown/talked about how to deploy website for external users? I mean

http://meet.domain.com

Answer: This probably will not be covered in much depth. This is a fairly straight-forward part of

deployment. The Meet URL just needs to be published by an HTTPS Reverse Proxy, such as TMG, and have

a certificate assigned that has the correct Subject Name and Subject Alternate Names, such as

meet.domain.com, dialin.domain.com, public.domain.com, etc. Along with the proper DNS entries

resolving these names.

http://meet.domain.com/

BEST answer below! Please and thank you!

10:10:44 PDT

Question: Are there any plans to add a hosted VOIP solution to O365?

Answer: You can never guess what MS is planning However, person-2-person VoIP and dial-in 3rd

part conferencing is supported today

10:26:59 PDT

Question: Hi there! I use to follow the Jump Start recorded sessions through MVA instead of the live

signal (because of the time difference, I'm in GMT+1) but I've found some of your Lync 2010 sessions and

I wonder if it's worth to watch those courses (to have some background on the product) or I'd better

forget about Lync 2010 and study Lync 2013 directly. What would you recommend?

Answer: There have been some significant changes. I'd say it really depends on what your organization or

your clients are using and what you need to do. My approach would be to scan the slides for each session

to see if there are details that will be relevant to you.

10:30:49 PDT

Question: Hey any expected timeline for the 336 videos being available ?

Answer: Sorry about the delay on those. We are finalizing the self assessment quizzes and processing the

video. I expect to have them published next week.

10:31:04 PDT

Question: How to implement DID to route to a Response Group?

Answer: Hi imag - we will be touching this in the voice features module/demo


Q&A Log


10:40:27 PDT

Question: Main number must be unique? But extensions need not be unique? Right?

Answer: Hi Sahil - actually the opposite; the main number may be the same as long as the extensions are

unique

10:57:58 PDT

Question: Is MTP central media processing needed for lync trunk?

Answer: Select the

11:03:20 PDT

Question:

> Quoted question: Is MTP central media processing needed for lync trunk?

> Quoted answer: Select the

Answer: Select Centralized media processing check box if there is a well known media termination (for

example a PDTN gateway where the media termination has the same IP as the signaling termination).

Media bypass is only supported if this option is selected. It depends on your trunk

11:05:40 PDT

Question: What is the role of bandwidth policy server? Why this service is installed on edge server?

Answer: Hi Sahil, Great question. The bandwidth policy service is a service supporting call admission

control or CAC for short. With this role you can apply bandwidth policies to control concurrent media

sessions on WAN links, between regions and sites. This role is installed initially on the front end server. All

clients will start polling for bandwidth availability there. If you add an Edge server the edge server or pool

will be used for this service. Clients will then poll the edge server for available bandwidth.

11:10:53 PDT

Question: So if you have one main DID and no unique DID's for each users we would use a Route for

these or an incoming dial plan? Do you have to have unique DID's for each user?

Answer: Do you mean if you have 1 switchboard number? No route is needed for inbound routing. If you

want the non did users to call outward you need a route. You need to consider letting the telco switch to

a default outbound number presentation or control this with a route that includes a overruling phone

number for outbound number presentation. Each user needs a unique user DID or none.


Q&A Log


11:11:29 PDT

Question: Dear Team, Requesting you to answer as my of questions posted as it will surely increase value

to this jumpstart and useful for others to learn technology..

Answer: Hi Sahil, Just got in based on technical difficulities. The team will try to do its best to answer all

questions.

11:19:22 PDT

Question: Brian In my case we have a DID in a site A: +552132193004;Ext=3004 and in site B:

+557121193004;Ext=3004 What is the recommendation for this case?

Answer: The extension needs to be unique. if this is overlapping you need to review the global number

plan. What you could do is prefix with a unique site number +557121193004 user from site A = site prefix

1 : +557121193004 ;Ext=13004 and site B = site prefix 2+552132193004 ;Ext=23004. or try ext=2193004

or ext=1193004. Overlapping is always a challenge. make sure it is as short as possible and when it is long

enough to match the digits in local calls make the normalization rule be more unique and higher on the

Normalization rule list. I'm sure there are more options. Remember that usually implementing Lync.... the

extension is not longer important to remember, because you can call names. For dialin conferencing and

logging in on IP phones, you need to account for a extension that is unique. prefix with a site ID usually

fits all needs then. Try it out in the lab and play a little with it.

11:21:13 PDT

Question: ohhh...Brian sir i am not able to assign same tel uri for 2 different users

Answer: Hi Sahil, It is true. The user URI needs to be unique. If you need to share a number, a response

group will help you out.

11:21:42 PDT

Question: Can multiple logical routes between lync and voice gateway?

Answer: Yes, This is unlimited as far as i know.

11:22:20 PDT

Question: great explanation fot contact objects...Cheers!!!!

Answer: Thanks that's helpful feedback!


Q&A Log


11:23:11 PDT

Question: How are unassigned numbers identified by lync routes

Answer: Unassigned numbers are part of the phone number lookup process. If no match is found the

Unassigned number service will pick up as last resort.

11:33:03 PDT

Question: How pririty is assigned to routes in a given pstn usage?

Answer: Good question Sahil. If you assign 2 gateways to a single route, the route will be load balanced.

If you create 2 routes and assign them to the same pstn usage you can change the order and configure

the primary and backup route.

11:35:55 PDT

Question: Is there a way for a response agent to call forward to his mobile, if, let's say he is stepping out

of the office?

Answer: Hi Rohit, You could configure the response group with a failback number, that is the mobile

phone. But you will have 2 voicemail places...

11:37:06 PDT

Question: How many trunks can be created from Mediation server to gateways? How many gateways can

be associated to a single mediation server?

Answer: This is unlimited as i know of.

11:38:02 PDT

Question: What are the maximum digits in E.164 format?

Answer: 15


Q&A Log


11:40:27 PDT

Question: How do server use address book service to convert numbers into E.164 format?

Answer: Numbers are either E164 or not. In essence Lync takes the numbers into the address book that

starts with a plus sign. You can manipulate company phone number notation in active directory by

creating a supporting file on the abs fileshare. company_normalization_rules.txt more info on this here on

this fantastic blog post. http://blog.schertz.name/2010/09/lync-2010-address-book-normalization/ . This

still applies for Lync 2013.

11:43:59 PDT

Question: Is there a good link that explains how Lync does Expressions like discussed in the session?

Answer: It is basically .net Regex based. http://en.wikipedia.org/wiki/Regular_expression.

11:44:59 PDT

Question: How long can You make hair?!

Answer: Long hear takes Long care, Grzegorz.

11:49:47 PDT

Question: in ocs 2007R2 resource kit there was the RouteHelper tool that was very useful

Answer: It is built into the Lync Server Control Panel.

11:50:02 PDT

Question: Justify: Media bypass and CAC are mutually exclusive....I have one site called XYZ...Its backup

site is ABC...Site XYZ failed..Site failover took place . But lync policy server located in site XYZ is down.Will

CAC permissioons will be allowed.If no, justify.

Answer: If a single pool with cac services goes down the call will pass, disregarding the policies. To

account for this, you could deploy 2 pools in 2 sites (cac services are site specific) and deploy cac on both

pools. Pool pair these pools. If 1 pool fails. You can fail over the users, the users now home on the 2nd site

and use the same global cac BW policies. BW polling is done by the clients on the new pool.

Q&A Log


11:53:34 PDT

Question: With dialplans, is there a way to manipulate what's displayed (ANI) for outbound calls?

Example: Someone from Costra Rica outdailing and instead of their actual number being displayed, say a

US number is displayed instead?

Answer: Yes, on your Routes you can select Suppress caller ID, and then you can specify the Alternate

caller ID and you can put whatever you want there.

11:55:22 PDT

Question: how about having capability of partitioning between PDTN/CUG in dialplan or normalization

rules ? as many contries like India need it... can we have two lines in Lync client one for internal & other

for external calling only ?

Answer: You can have 2 lines with seperate numbers. Private line, and normal line. You already can get 2

calls. Answer 1, then take the 2nd call, this automatically puts call 1 on hold. You can handle the 2nd call

and get back to the first.

11:59:33 PDT

Question: Thanks Jonathan

Answer: Its always good to help out fellow Lync community members!

12:00:19 PDT

Question: After how much period the call be forwarded to voice mail? Which AD attribute is responsible

for this?

Answer: There is no AD attribute for this setting. This is a Lync user specific setting. It's configurable in the

unanswered calls rules.

12:01:05 PDT

Question: Can we have local subscriber access number for users?

Answer: hi Sahil, Please define Local.


Q&A Log


12:02:16 PDT

Question: What do I have to configure to conforming to the law when I have a SIP Trunk . The new law

says in Germany that waiting time in a Hotline must be free of cost.

Answer: I think you have to check this with your SIP trunk provider, BerndL

12:03:47 PDT

Question: Is there going to be a Multi-Tenant Pack for 2013 like there was for 2010?

Answer: I think this is already available. http://www.microsoft.com/en-

us/download/details.aspx?id=39089

12:04:34 PDT

Question: Thought it was a hair break :o)

Answer: Never BREAK the HAIR!

12:06:34 PDT

Question: We can assign the number from unassined nu mber range and lookup process will take that

number out from that range. However, you must keep a track of assingned and unassigned numbers to

make things easier.

Answer: The unanswered number range can overlap the dialplan. It will only be the final endpoint of the

call if no user is matched to any other service or user with the dialed number within the dialplan.

12:08:55 PDT

Question: Can PSTN routes be assigned through a cost policy? We have lower fares when calling to

certain numbers using a determined carrier, so basically we would like that all calls made to a block of

numbers be sent through a fixed route.

Answer: Hi Eduardo, Great real world example you gave here. Yes you can create voice policies to meet

that requirement.

12:12:09 PDT

Question: Jonathan, we have the same scenairo. Two route to same PDTN usage. For any reasone, if route

one is down, PSTN usage with route two works fine But one will notice a short delay towards the call

establishment.. unless you change the prioirty...

Answer: Great to hear you are already at this point of expertise. It will surely help you on the exam!

12:13:32 PDT

Question: Lync along with Aspect would be complete solution for a contact center solution.Lync response

groups dont support skill search, agent reporting,programmability....We have write a code in UCMA 3.0 to

implement whispher facility..Lync response groups cannt replace contact center alone......

Answer: A structured approach to define the business needs is mandatory to understand if a certain

solution fits all the needs.

12:14:45 PDT

Question: EnableVoicemailEscapeTimer - Enables or disables the escape timer.

PSTNVoicemailEscapeTimer - Specifies the timeout value in milliseconds. The default value is 1500

milliseconds, and the value can range from 0 milliseconds to 8000 milliseconds.

Answer: Thanks for your addition Jonathan. It is good to test this out in a test lab before implementing

such a solution into production.

12:15:32 PDT

Question: What are the minimum digits in E.164 format?

Answer: +d

12:28:53 PDT

Question: There are multiple trunks in a same route? How gateways are preferenced?

Answer: They are load balanced.

12:55:06 PDT

Question: Set-CsRoutingConfiguration -EnableLocationBasedRouting $true do?

Answer: You can use this cmd for explanation of any powershell cmd. get-help set-csroutingconfiguration

-detailed . you can do this with all powershell commands.


Q&A Log


12:55:54 PDT

Question: Good to know that Lync 2013 supports location based routing..... It would be specially usefull in

india...as no third party tool would be required like "power-routes" .that restrict IP-to-PDTN routing.please

focus/through light on this topic. Is location based routing enabled by default???

Answer: you need to configure Location based routing first, before using it.

12:58:32 PDT

Question: Question about normalization rules: Is processing stopped after one matched successfully, or

are latters processed as well? Example: Rule 1 ^(\d{4})$ -> 66$1 Rule 2 ^(\d{6})$ -> +34985$1 If an

internal user dials 5678, what is the result?

Answer: I can give you the answer. But it is more fun if you guys try to solve it for good practice. Who

dares?

12:59:05 PDT

Question: is there a exam to upgrade my MCITP Communication (Lync 2010) to MCSE Communication

(Lync 2013) ?

Answer: There is none. You need to do both 70-336 and 70-337 exams.

13:03:36 PDT

Question: Why early media support is necessary? what does SIP 183 signify?

Answer: Early media provides early setup of the call over IP networks. This will setup the media path in an

early stage. The initial invite of the User Calling sends over ip addresses and ports for the other party to

send media and rtcp to. In the SIP 183 (early dialog) the called party sends back its ip addresses and ports.

This way, before the user picks up the phone (giving 200 OK) the media path will already be established

after media testing of all provided ip addresses and ports, providing a seamless call experience.

13:05:48 PDT

Question: "SIP 2.0 488 NOT ACCEPTABLE HERE" Is this the indication for call-reroute??

Answer: This can be lots of things around incompatible session setup.. Usually this is a response to a

failed pstn session with a 3rd party pbx for example, that did not negotiate matching codecs.

Question: Is there a way to be notified when recording of Jump Start 336 will be available?

Answer: There is an email that is generated automatically which will be sent to you when we have it

13:43:22 PDT

Question: If the block of number is shared between two systems is there any way to easily configure

unassigned number as a block or can you only put in ranges asociated with Lync and not the numbers

associated with the other system

Answer: You can, but in a migration scenario it is better to use the PBX systems announcement service

(similar) first and then plan moving to the Lync system for this. Or vise versa. Depending if the PBX is

uPDTream or share a gateway with Lync.

14:00:45 PDT

Question: is it possible to broadcast radio instead of music on hold ?

Answer: Hi Benoit, interesting question. It is not a native feature of Lync. That said... It could be created

with 3rd party solutions, I think.

14:20:14 PDT

Question: Do we see the new feature - Call pickup?

Answer: Hi Carsten - no regarding Group Call pickup. This presentation is pre-CU1.

Q&A Log


14:37:04 PDT

Question: May I ask an unrelated question that probably will be covered in module 7 while we are

waiting:Why is it the Lync party receiveing a session request that is checking bandwidth availablity with

the CAC service and not the initiating party? (page 7-12 in the 20337 book)

Answer: Good question Mattias, but pretty heavy, my guess and understanding is that the Receiving

party knows all IP subnet information of both parties first, because in the initial invite the Caller party

sends its subnet information in the SDP field and the Called party already knows its own IP subnet

information. So it would be quicker to check by this party than, waiting for the caller party to receive the

183 with IP subnet information from the Called party, and then check. Also note that media testing starts

as soon as a client receives the other party's IP and Port information. It is important for the client to know

if there is BW available over a WAN before Media testing. If there is no BW available it would not make

any sense to negotiate the blocked route as a valid option or wait for the Caller party to determine if the

call can be made or not... adding latency in the call setup process.

14:41:55 PDT

Question: @MartinKulir - To upgrade from MCITP (Communication /Lync 2010) to MCSE Communication

you only need to pass 336 and 337 not 417

Answer: Please note that 417 is the MCSA upgrade for MCITP windows server 2008 (r2) certified people.

You need to be MCSA for windows server 2012 and pass 336 and 337 to be MCSE Communication. 417 is

the upgrade path. 417 covers 410,411 and 412. If you did not have MCITP yet you should follow 410,411

and 412 for MCSA + 336 and 337. If this dazzles you because this is a lot of info in a small screen look

Question: Will we see some examples of E911 routing? Would be handy.....

Answer: Hi Ed - next module is configuring and deploying emergency services.

15:18:27 PDT

Question: what was the url that passed the credentials that Brian just mentioned?

Answer: Hi Liz - Internet Explorer will pass your logged in credentials to any website that is listed in

Options | Security | Local Intranet | Advanced. In our demo we added *.onprem.local to the list as the

website address was covered by this wildcard. If your control panel was set to lyncadmin.contoso.com you

could do the same by adding *.contoso.com.

15:20:02 PDT

Question: how much load should we expect if annonimity is enabled & have 50 simultanious calls are

expected simultaniously ? (cause it's good to preserver the identity of that person.)

Answer: Hi Bushan - the load depends on the power of the server running the application service and the

number of servers in the pool. The best way to know is to test in a pilot and gather your own numbers on

your hardware.

15:20:53 PDT

Question: At some point can you describe routing for an analog device that has analogfax set to true. The

media is supposed to bypass LYNC and it then seems to ignore the voice policy and route out the

gateway/sbc. Can you explain the call flow outbound from the analog device with analogfax true ?

Answer: Hi dachris - if there is time we will definitely discuss analog; however the content is not on the

exam so no worries there.

16:20:12 PDT

Question: Trying to multi task and not doing a good job so I have missed quite a bit of content. Is this

Question: Hello, Sudhakar from Bangalore, India

Answer: Hi!

09:14:07 PDT

Question: Does FEC inreases BW requirements?

Answer: Yes and no. FEC provides in redundant packets. Thus doubling the BW used. However, usually if

FEC is utilized often in a deployment, you have a big network problem. So planning for BW utilizing FEC is

not recommended. And thus not a requirement.

09:15:25 PDT

Question: I'm working with an environment which has the bandwidth, but just doesn't seem favourable to

UDP traffic.

Answer: Hi Korbyn, Have you tried implementing QoS? Other wise you should check with the network

team or if that does not help check with Microsoft support to solve the issue.

09:16:52 PDT

Question: Does Lync changes video codec or video frame rate?

Answer: Yes, depending on policy or available BW and network conditions.

09:17:57 PDT

Question: IN FEC is good solution for lossy wifi network?

Answer: FEC is not a solution i think. FEC kicks in when you have more than 5% packetloss. That means

you should check and optimize your network rather than plan for FEC / Forward Error Correction

09:17:59 PDT

Question: Do you have the slides for today?

Answer: We will have the slides posted very soon.

09:18:43 PDT

Question: Whats sampling rate in RTAudio narrow BW?

Answer: 8 kHz

09:19:56 PDT

Question: can you force FEC to be on? my impression it only turns on during a call as needed

Answer: Hi Korbyn, good question. It only kicks in when the Packet loss surpasses 5%. Its dynamic and

changes realtime in the call.

09:23:22 PDT

Question: Siren Codec is a worse Protocol. !!!!

Answer: Hi Sahil, I must say. I do not agree on you with that one. Siren is used in Lync 2010 and OCS. Had

lots of good conferences with it. In lync 2013 we use G.722 Stereo and G.722. SIren is also still used for

fallback and / or legacy interop. G.722 is just sooo much better.


Q&A Log


09:25:19 PDT

Question: no udp is not always used, if we disable udp port 3478, we have to send media on tcp port 443

Answer: Correct. both UDP and TCP media connectivity candidates are negotiated in the call setup. UDP

is just the the prefered delivery method, because it is faster and has less overhead.

09:29:11 PDT

Question: we have, but there's this constant issue that comes up frequently where media traffic from the

FE-to-Client is poor, with packet loss and high concealment, but traffic from the client-to-FE is perfectly

clean. Not a lot of users, 25 maybe, and lots of available bandwidth

Answer: Maybe MS support can help you out sort this out. Could be many things. Virtualisation processor

overbooking, network interface broken, Driver issues, Hardware scaling.

09:32:50 PDT

Question: does Lync support AVC & SVC codecs in h.264 ? does it support h.263 as well ?

Answer: Hi Bhushan, Yes, H.263 is supported. For example when a Lync 2010 client joins a video

conference.

09:34:44 PDT

Question: Does G.722 stereo codec is ever used in Lync 2013 conferencing?

Answer: Good question. Supported endpoints send this. Room systems for example, support stereo

sampling.

09:35:18 PDT

Question: Why VLAN number for voice is always lower than data VLAN? What might be the technical

reason behind it?

Answer: Hi Sahil, There is no technical reason to do so.

> Quoted answer: Correct. both UDP and TCP media connectivity candidates are negotiated in the call

setup. UDP is just the the prefered delivery method, because it is faster and has less overhead.

Answer: correct Sahil. TCP can be used over port 3478. UDP is prioritized. Didn't mean to state that only

UDP was used. thanks!

09:41:44 PDT

Question: Suppose, lync phone is connected to lync server via edge? Is Qos supported?

Answer: It actually is not. not that the phone does not support this.. but the network between the External

Endpoint and the Edge server are not managed. There fore you can assume that no QoS will be used that

we can control.

09:43:47 PDT

Question: does this include remote users using Direct Access also...since this is IPsec based?

Answer: Hi BRad good question. You should bypass the media going true the Direct Access tunnel. You

can do so by blocking DNS resolution for the internal Front end servers. Good article to look at is

here:http://blogs.technet.com/b/nexthop/archive/2011/11/15/enabling-lync-media-to-bypass-a-vpn-

tunnel.aspx

09:45:47 PDT

Question: when we add another party to the call that is on the PDTN, what is doing the transcoding?

Answer: Great question Glenn! The mediation server will be in the media path to transcode media

between the PDTN gateway / SIP trunk and the Conferencing server.

09:51:00 PDT

Question: Hi. how is the current amount of used bandwidth measured or tacked?. I mean you define your

CAC policies and have your QoS, but for example users on the same office/subnet start placing calls, at

some point there´s no more room and next one is denied by CAC. How Lync knows we hit the limit?

Answer: BW is reserved and monitored. The availabillity of BW is therefore known and when the limits

hits its cap limit the call will be denied, alternate routes like PDTN reroute and EDGE reroute are then tried

by the Lync client.

Answer: Very thoughtful of you. That is fine, as long as anyone else can also put in their questions in as

well.

10:10:56 PDT

Question: When do we get the Public QA, all two days in one file?

Answer: It will be emailed to you within a couple days. We will also post it with the slides and the

recordings late next week.

10:11:48 PDT

Question: (the forward call option on the Lync client doesn't work if the person is an agent)

Answer: Personal call flows are disregarded in Response group flows. You can only control the call flow

within the Response group service. You can try using fall back configuration for this. Make sure you test

this out before going all in.

10:12:55 PDT

Question: when will the recordings of these sessions be available online?

Answer: Yes, we will post the recordings late next week. You will get an email when they are available and

you will be able to find them from the MVA live events

page https://www.microsoftvirtualacademy.com/LiveEvents.aspx

10:14:32 PDT

Question: Hi Jonathan. Does that mean Lync accounts the number of sessions? how is BW consumption

monitored?

Answer: Lync maintains current BW usage of each session and releases this when the call is finished.

10:16:28 PDT

Question: Traffic comming from Sip trunk can support Qos?

Answer: All traffic can support QoS if the end to end path is fully managed.

Question: will the slides be available shortly?

Answer: If you refresh your browser you should be able to get them now.

10:22:55 PDT

Question: if we set up CAC, it is possible to grant priority to users like managers, executives etc??

Answer: Hi Juancho, great question! You can make Voice policy's for the managers and executives, where

you enable BW Policy override. This will make the client ignore the BW policies.

10:24:37 PDT

Question: is there a planning tool for CAC?

Answer: I believe it is in the works and not publicly available yet.

10:25:52 PDT

Question: Why Voip is not tagged with CS7 DSCP? It is tagged with EF i think so...And for file transfer AF1

is tagged which is equivalent to best effort. please correct me if i am wrong

Answer: You can choose your own values, but EF / 0x46 is best practice for audio. AF / 0x34 for video.

There are some priorities that can't be used because they are reserved for inter router communication.

10:27:10 PDT

Question: awesome!! thanks Jonathan

Answer: You're very welcome!

10:30:48 PDT

Question: Media bypass saves WAN bandwidth!!!!! for branch office

Answer: That is correct. In PDTN call scenario's that is true when there is a local gateway in that site, that

supports media bypass.. This is possible because the Lync client, since Lync 2010 supports G711. No

mediation is needed. if both endpoints talk the same language.

10:35:37 PDT

Question: SIP trunks are directly terminated to mediation server? How does media bypass possible in SIP

trunk. If Sip trunks sends G.711 codec, Still transcoding of media is done?

Answer: With a SIP trunk... when do you need media bypass. Usually the Telco would not allow you to do

this.


Q&A Log


10:36:44 PDT

Question: CUCM gateway and lync server are connected via lan network. we can savely do media

bypass...right...does the lync dial in conference calls will be meda bypassed?

Answer: No. All G711 based traffic will go via the Mediation server to be transcoded to RTaudio for the

stream to join in the audio conference.

10:39:51 PDT

Question: can anyone please explain that does Lync support AVC & SVC codecs in h.264 ?

Answer: Try looking here: http://blog.schertz.name/2012/07/video-interoperability-in-lync-2013/ There

are plans to directly and natively communicate between Lync 2013 and Cisco based Conference Rooms

later this year.

10:42:21 PDT

Question: I totally just missed all that about refer. Any documentation that explains what Brian was

explaining about refer and media bypass?

Answer: Refer support used in Lync is based on the IETF RFC3515. If you want to dive in look at the

following link. http://tools.ietf.org/html/rfc3515

10:44:43 PDT

Question: thnx jonathan for refer support

Answer: You're very welcome.

10:48:35 PDT

Question: Does Federation call supports CAC?

Answer: The path from the internal network towards the edge can be defined with CAC. for each Lync

10:51:52 PDT

Question: super! thank you. We are having a debate about how it acts in our environment and what it

does when we turn it on. (i.e. breaks things)

Answer: Remember. When turning off REFER SUPPORT, you might want o change the following settings

in power shell. set-cstrunkconfiguration -identity <trunk> -RTCPonActiveCalls $false -RTCPonHOLD

$False -EnableSessiontimer $True

Question: Jonathan Sir,Why comman area phones use contact object in AD? can the policies be applied

on contact object?

Answer: Common area phones are not bound to a user account. But you still require an object to refer a

pin code and configuration to. Therefore a contact is used.

11:52:51 PDT

Question: But contact object cannot be used to sign in???? Then plz ask them to explain

Answer: You configure a pin association and extention to the contact. That is how you sign in.

11:58:22 PDT

Question: can avaya phone be used with lync server

Answer: Give it a shot, but i guess it will disappoint you. It is best to stick to the certified devices lists.

11:59:39 PDT

Question: but the web service go to lync registrar and then request a certificate that is published to

phone? but how does the phone trust the cert published by web service . Do we have to manually install

rootca for this?

Answer: The root ca is automatically downloaded at first boot when provisioning is configured correctly.

12:00:55 PDT

Question: Can use Polycom IP321 or CX600 like Common Area Phone ?

Answer: Hi Robson - yes an LPE phone can login using PIN Authentication assuming your network is

configured correctly. Typically we do not however as they lose functionality.

12:02:13 PDT

Question: Can a Common area phone be a member of a Response Group?

Answer: Good question, Peter. This is not possible.

12:04:39 PDT

Question: what happens when the CA root cert is renewed in the CA server? will the new cert will be

deployed automatically or the phones need to be reset?

Answer: I'm not sure. I think that the new root ca will be downloaded again. But if it requires a reboot or

if this is automatically downloaded. I'm not sure. Better test these kinds of changes in a test environment.

It might also impact other applications as well.

Answer: I have a link for you to look at tested database activity. It is based on Lync 2010, however you

can pretty much use it for Lync 2013 as well. Do account mirroring if you are deploying this as additional

overhead.http://technet.microsoft.com/en-us/library/gg412771%28v=ocs.14%29.aspx

Question: Why wouldnt you use HyperV to gen a Microsoft demo enviroment?

Answer: Hi Adam - the backend is utizizing Hyper-V to my understanding; HOLSystems has created a

custom interface for presenting a closed demo environment. Given that we require a fairly large system of

servers , with remote access, HOLSystems was able to provide the access quickly.

Question: can i activate this Client logging with GPOs ?

Answer: Monitoring is turned on for all calls when the databases are deployed. CLient based logging can

be turned on by using inband provisioning. There are corresponding GPO settings or registry settings to

control endpoint client logging. But this is for troubleshooting purposes exceeding quality reporting and

such.

Question: in case of Polycom IP321 do not support Pin Authentication.. still possible the use like Common

Area Phone ?

Answer: Hi Robson - a Common Area Phone - or CAP - is a contact object by definition. This means

without PIN authentication, there is no way to login to the phone. However, if policy permits, you could

create an AD account, provision it in AD, and even add the HotDesking option to a custom client policy;

you do add a larger scope of intrusion as the phone is logged in with a 'Service Account' but it could be

done

14:47:12 PDT

Question: What happens to response groups and call park service when my primary pool is down?

Answer: These are not failed over. For the response groups you could bring up the configuration by

deploying the backups for them on the backup pool. Needs manual intervention and manual backup

(meaning not part of backup service).

14:48:44 PDT

Question: Is an Active Directory replica necessary for branch offices?

Answer: Hi Diego - no. As long as the connection to AD and the pool is present at first login, a certificate

is returned allowing the phone/user to authenticate using the certificate without the need for AD.

14:53:03 PDT

Question: Brian are you typically deploying dedicated Lync mediation servers with SIP PDTN services in

addition to the FE pool, or do you rely upon mediation services built into the gateways as prefereed

deployment reference architecture? Interested on what you typically see out in customer base. Thanks.

Answer: Hi Andrew - that is a loaded question. Nearly every deployment is unique and every deployment

requires a different design. If the client has a branch office, it an SBA may be used if the level of user

importance is mid-low, and an SE/EE pool if the users are important. For the data center, collocated vs

standalone mediation has many determining factors such as number of concurrent calls, media bypass,

etc.

14:54:07 PDT

Question: So that means if the certificate happens to expire at the time of a WAN link failure, connectivity

to the SBA won't work anymore either as authentication will fail?

Answer: Roman, if you were ever so lucky or you had never logged in at the branch site, you would

simply not be able to connect until the WAN link was back online.
