Many options…
“How do I connect my existing Cisco Voice Infrastructure to my Microsoft real estate?”
“Which way can I provide a compelling user experience?”
“How can I communicate with my business partners, who are using Microsoft, from my Cisco Collaboration Solution?”
“What options do I have to integrate collaboration capabilities in my Microsoft Application Suite?”

Enterprise Voice Interoperability
A users view of the world…
Skype for Business only
• Reach corporate extensions
• Reach PSTN number
• Available via corporate extension
• Available via PSTN number
• Telephony feature set
In addition to previous use case
• Available via corporate extension on
both devices simultaneously
• Access to users on both platforms from
all user associated devices
• Telephony feature transparency
Skype for Business andCisco IP phone
Possible with Direct SIP Integration
• Integration with existing Cisco UCM system for access to corporate extensions and PSTN
• Telephony features only available within the Skype for Business Domain
Difficult to impossible to achieve
• Simultaneous reachability on both devices on different call control platforms (MSFT “Sim Ring” & CSCO “SNR”) high risk → call routing loops
• Telephony feature interoperability protocols SIP/QSIG not available with Mediation Server

Enterprise Voice Call RoutingSIP Trunk / Direct SIP Options 1/2
Flows show the SIP signaling and media paths in a SIP-trunk (Direct SIP) interoperability scenario

Enterprise Voice Call RoutingSIP Trunk / Direct SIP Options 2/2
With the introduction of Media Bypass in Lync 2010 the Lync client can initiate direct G.711 media streams. Media paths is not hair pinned through the Lync Mediation Server, no transcoding. Signaling via the Mediation Server.
Review Microsoft guidance regarding Media Bypass http://technet.microsoft.com/en-us/library/gg412740.aspx
Straight forward in a centralized (single site) topology without WAN links.
More complicated in a distributed topology with one or more branch - check the following:
Media Bypass shall only be utilized between WAN sites without bandwidth constrains
Media Bypass and Call Admission Control (CAC) are mutually exclusive
Media Bypass mandatorily requires all media to be represented by a single IP address – the reason why in the above example a Media Termination Point (MTP) has to be inserted.

“To Bypass or not to Bypass that is the question”Media Bypass pros and cons
Single Site Deployment
• More scalable – no Mediation Server transcoding required
• LAN bandwidth CAC not required
• Simple redundancy configuration with Cisco UCM cluster and Microsoft Mediation Server Pool
Complex WAN Deployment
….Remote locations
• Highly complex to configure and troubleshoot
• Mutually exclusive to CAC, required in some WAN topologies
• Remote site MTPs required to keep media local
• Further complicated when redundancy is required
• With roaming devices (i.e. PCs) certain call scenarios will still result in hair pinning and suboptimal media routing

Enterprise Voice Call RoutingMultiple Site example (Lync / Skype for Business to Cisco UCM)
To keep media local to a site each site requires a local media resource
Alternate media IP definition in Lync trunk configured matches IP address of single media resource in MRGL/MRG of the trunk on Cisco UCM side
Multiple sites require multiple trunks
… and multiple MRGs, MRGLs and media resources
… and multiple SIP security profiles, because unique identification of each trunk on Cisco UCM based on the signaling port (UCM side trunk identification based on peer IP address and local signaling port)

Enterprise Voice Call RoutingLync Media Bypass implications on redundancy
Fixed media IP configuration for GW on Lync forces 1:1 relation between inbound SIP trunk on Unified CM and MTP
Can not use MRG and MRGL for intelligent MTP selection (scalability, redundancy)
Availability of SIP trunk depends on SIP signaling peer and MTP availability
… which can not be monitored via SIP OPTIONS ping
Only indication of failing MTP allocation for inbound EO call from Lync:
If UCM fails to allocate a MTP call can be signaled failed and left to Lync to reroute using different SIP trunk
Outbound calls from Unified CM need to be EO and have to be via MTP (MTP required – Media Bypass)

• “Why is interoperability so complicated?”
• “Why do I need so many different boxes doing different things to achieve my goal?”
• “Why does it have to be so expensive to do interoperability?”
• “How can I seamless communicate with my business partners independent if they use Cisco, Microsoft or some other standards based solution?”
• “How can I do a phased migration after an acquisition to a unified Cisco solution?”
Things have changed..
• Microsoft deprecated support for XMPP Microsoft tested and supported only for Google Talk https://technet.microsoft.com/en-us/library/jj205134(v=ocs.15).aspx

Talking about DomainsRecommended Deployment – Flexible Jabber ID (JID)
Make the email address the multimodal communication address
Most Microsoft deployment user email address for SIP communication Mapped to msRTCSIP-primaryuseraddress attribute in Active Directory
Required for deployments utilizing multiple distinct email/SIP domains in a single Cisco UCM IM&P cluster or multi-cluster environment
Available in Cisco UCM IM&P with version 10.x or higher
Cisco UCM Directory synchronization allows to select attribute email or msRTCSIP-primaryuseraddress. Recommendation for migration scenarios is the to user the later.
© 2018 Cisco and/or its affiliates. All rights reserved. Cisco Public 52BRKCOL-2610
Talking about Domains Configuration steps for Flexible Jabber ID
• Cisco UCM Directory LDAP Sync Statement, configure directory URI mapping
• Cisco UCM IM & Presence, configure Advanced Presence Settings
IM Address Schema – Directory URI
Systems will automatically import all domains configured in Active Directory
Existing buddy lists will be migrated to new flexible JID format <user>@<domain>
• Configure Cisco Jabber to use Flexible JID

A word on Contact Search
• Cisco Jabber contact sources
• Active Directory/LDAP
• Cisco UDS (service provided by Cisco UCM)
• Outlook personal contacts
• Microsoft Skype for Business/Lync
• Clients have local address book, created by nightly synchronization with AD by AddressBook service of Microsoft server (Lync or S4B)
• Only includes users that are enabled for Lync/S4B, aka that have msRTCSIP-primaryuseraddressattribute set (we get to that in a second)
Source for contacts
Cisco UCM UDS data source required for clients outside the corporate network using Mobile
Remote Access (MRA), Active Directory source not available when outside Corp. network and
not on VPN. New UDS Proxy service on Cisco UCM allows enhanced scalability beyond
160.000 directory items. Requires Cisco Jabber 11.7 or higher.
BRKCOL-2610
© 2018 Cisco and/or its affiliates. All rights reserved. Cisco Public 54BRKCOL-2610
A word on Contact Search
• The Microsoft AddressBook service
will only sync contacts that have
attribute msRTCSIP-
primaryuseraddress set
• For migration screnarios the attribute
is set for all existing Microsoft users
• During migration when net new users
are added to Cisco UCM (never
enabled before for Microsoft Lync or
S4B) msRTCSIP-primaryuseraddress
must be set manually in Active
Directory so these users are included
into the AddressBook file that is to
Microsoft clients
Microsoft Address Book service in the context of migration

A word on Contact SearchTemporary Presence Subscription
When a users search for contacts (either contact source in Cisco Jabber or AddressBook for Microsoft
the search results are displayed including a snapshot of the users presence.
Since this is a temporary display of information, clients do not establish a full “subscription” for each of
the users in the result list. This is called a temporary presence subscription.
Up until now this issue prevented Jabber or Microsoft users to see presence in the search results.
With Cisco UCM IM&P 11.5.1 SU4 this issue has been addressed for Cisco Jabber clients
Cisco is actively investigating to provide a feature enhancement that will also solve this for Microsoft
Lync and S4B clients – not yet committed to a specific release
This issue does not affect contacts that have been added to the buddy list of either clients. Full presence
is displayed in that scenario.

What we need to design and configure

Collaboration Infrastructure considerations
Using basic (default) SIP routing – Cisco IM&P will route all requests to Microsoft that match any the configured domains
Using advanced SIP routing – Cisco IM&P will verify that the destination user exist as a Microsoft (Lync or Skype for Business) user. Improves routing of mistyped/wrong SIP URIs
Advantages of the Expressway classification approach
Expressway SIP broker
Inbound and Outbound requests take different paths, makes configuration and
troubleshooting more complicated
Expressway traffic classification
Inbound and Outbound requests routed via same paths
• Single TLS per subject UCM IM&P
• Single TLS configuration S4B FE
• Modification of S4B FE certification optional (client/server role)

Configuration steps for Cisco Expressway classification
Required Configuration Steps … (1/2)
• Configure certificates on Lync and Cisco UCM
Highly recommended to use CA based certificates on both systems (Enterprise CA)
• Configure security parameters on Cisco UCM IM&P (ACL, TLS peer, TLS context)
Single neighbor, either single Cisco Expressway or Expressway Cluster
• Turn on Partitioned Intra Domain Federation & Configure SIP static route(s) on Cisco UCM IM&P
Single route per domain pointing to Cisco Expressway next hop
• Configure security parameters on Microsoft Lync (Trusted Application, Computer, etc.)
Single destination, Cisco Expressway
• Configure SIP static route(s) on Microsoft Lync
Single route per domain pointing to Cisco Expressway next hop
