Design Guidelines

HP MSR Voice in a Microsoft Lync Environment

HP MSR in Microsoft Lync Open Interoperability Program (OIP) Microsoft Lync UC Open Interoperability Program (UCOIP) certification indicates that the PSTN gateway can be deployed in Microsoft Lync systems. Used a SIP media gateway in a Microsoft Lync environment, the HP MSR Series provides:

• Integrated voice gateway

o Microsoft OIP certified to make/receive calls

o Wide range of WAN, LAN, voice interface options

• Reliability and cost savings

o Enables reliable real-time communications

o Facilitates calls over the PSTN

• Open and scalable

o Based on open standards e.g. Session Initiation Protocol (SIP)

o Highly scalable routing and voice platform

o TCP and TLS – make/receive call

o Interoperable with 3rd party UC solutions

o Based on open standards and Session Initiation Protocol (SIP)

The HP MSR voice solution is provided by software and voice modules. The voice software functionality of the HP MSR Series is built-in to the HP Comware software of the router. Voice modules are inserted into the router to provide physical voice connectivity, such as local analog devices to FXS ports, central office POTS lines to FXO ports or PSTN digital trunks to T1/E1 voice ports.

The diagram below illustrates different HP MSR Series router models alongside the type of modules that are supported. Note that SIC modules can be installed in any HP MSR30 Series router and HP MSR50 Series routers with the MPU processor module.

Figure 8: HP MSR Series Routers and Voice Modules

HP FBRA Router-based UC with Microsoft Lync Deployment Model In a unified communications deployment model, the branch office is part of a centralized unified communications and collaborative environment. IP phones at the branch get their service from a centralized IP-PBX or UC system via WAN connectivity. The IP phones get their IP address from a local or centralized DHCP server. The IP phones may also require authentication using 802.1x or LLDP-MED.

The branch office may have analog devices such as analog phones or facsimile (fax) machines. A small branch office may have only a few analog lines to the central office for Public Switched Telephony Network (PSTN) connectivity using FXO interfaces, or larger branch offices may have T1/E1 connectivity when they require more than a few lines to the PSTN. Typically, connections to the PSTN for large scale connectivity is done at the central site, leaving the requirement for one or more analog FXO lines to the central office for emergency calling or survivability use.

The diagram below illustrates this deployment model.

Figure 9: HP FlexBranch Unified Communications Deployment Model

Key requirements for a unified communications deployment model include:

Applies to all HP FBRA reference design models Unified wired and wireless access Voice on HP MSR Routers

o SIP call control, dial plan, digit manipulation o Analog FXO/FXS connectivity to devices and PSTN/PBX o Digital T1/E1/ISDN BRI connectivity to PSTN/PBX o Analog voice survivability when power fails

Integration with Microsoft Lync o HP MSR as a SIP media gateway o HP Survivable Branch Module for Microsoft Lync o HP 4110 and HP 4120 IP Phones

Integration with Avaya Aura o HP MSR as SIP survivable media gateway

Integration with other 3rd Party vendors o Support for LLDP-MED, CDP on switches and routers

Voice interfaces supported starting with MSR20-1x Series and all higher-end models Connect local analog phones, modems, fax machines Connect to PSTN or PBX Configure rules for number matches, number substitution, and call routing

Connectivity of analog devices and analog lines to the PSTN is illustrated in the diagram below.

Figure 10: HP MSR Series Analog Voice Connectivity

Wide variety of voice interface modules The HP Multiple Services Router (MSR) Series offers a flexible, modular design that delivers integrated, concurrent services on a single platform, creating operational efficiencies, reducing costs and maximizing precious rack space and power. The HP MSR Series features a comprehensive set of integrated modules for voice and data interfaces that provide routing, switching, and voice capabilities to deliver the functionality of multiple appliances in a single platform.

The HP MSR Series provides modular connectivity for voice interfaces, including:

Provides analog and digital connectivity o FXO, FXS, E&M, E1, T1, ISDN BRI S/T interface modules

FXS - to analog subscriber station FXO - to PSTN/POTS in central Office

Includes HP MSR SIC, DSIC, MIM, FIC, DFIC module types Various densities

The HP MSR Series routes support a wide variety of interfaces implemented on HP MSR SIC, MIM, or FIC interface modules. The router model type determines the type of interface modules available, and will also determine the density and performance characteristics of the interface modules. There are different HP MSR interface module types to support the different HP MSR models, providing a full range of router interface solutions based on performance, density, and resiliency.

Examples of HP MSR voice interfaces are shown in the figure below.

Figure 11: Examples of HP MSR Series Voice Interface Modules


11

Voice Interfaces Modules available on MSR Models Voice interfaces are supported on MSR20-1x through MSR50 Series. The HP MSR module types that are supported on the various HP MSR Series models are shown in the figure below.

Table 1: Voice interface module support for HP MSR Series models

HP MSR Voice Interface Scalability Together with its modular nature and variety of models, the HP MSR Series can provide the scalability needed for our customers. The scalability of the different kinds of voice interfaces on the different HP MSR Series models is shown in the table below.

Table 2: Scalability of HP MSR Series Voice Interfaces

The values in the table above are based on:

Maximum available FXS, FXO, E1, and T1 modules 30 voice channels per E1 port 23 voice channels per T1 port

HP MSR VPM and VCPM When voice T1 or voice E1 interfaces are required on an HP MSR Series router, a Voice Processing Module (VPM) and Voice Co-Processing Module (VCPM) is also required.

Voice Processing Module (VPM) o Voice DSPs to do coding/decoding for voice interface cards o Required for voice T1/E1 SIC, MIM, and FIC modules o VPM can be installed on motherboard or MIM/FIC o SIC can only use the VPM on motherboard o Install as many VPM’s as are needed for total cumulative # of channels (available in

8, 16, 24, or 32 channels) Voice Co-Processing Module (VCPM)

o Provides the TDM voice clock and global TDM bus

o VCPM on motherboard is needed for 1 or more T1/E1 SIC If only 1 T1/E1 voice SIC, need VCPM on motherboard Except MSR30-10

o MIM/FIC interface card has fixed built-in VCPM Cannot be moved to the motherboard (it is different)

o If more than 1 T1/E1 voice MIM/SIC/FIC, need VCPM on motherboard

HP MSR Series as a PSTN gateway for Microsoft Lync This section describes design guidelines for using the HP MSR Series as a PSTN gateway for Microsoft Lync.

SIP and HP MSR Series Routers Session Initiation Protocol (SIP) is the standard signaling protocol used for many solutions and endpoints common to Unified Communications solutions, including but not limited to video conferencing, IP phones, IP-PBXs and Internet Telephony Service Providers (ITSPs). The HP MSR Series provides built-in SIP with no additional costs to enable this functionality. Different SIP roles supported by the HP MSR Series include:

SIP Media Gateway o Allows communications to internal analog devices such as fax machines or analog

phones typically via FXS o Allows communications to the PSTN for analog lines via FXO or digital trunks via

E1/T1 SIP Server (registrar/proxy)

o Allows IP phones to register, which is used for example for survivability mode SIP Trunking

o Allows communications with an IP-PBX (like Avaya Aura) or an ITSP

The diagram below illustrates HP MSR Series SIP communications.

Figure 12: HP MSR Series SIP Communications

The HP MSR Series supports basic SIP Trunking, which allows customers to replace local PSTN connections and fixed costs with an all-IP solution between internal IP-PBX and ITSP using SIP trunks. HP MSR can provide basic SIP Trunking for inter-connecting SIP systems, but does not provide Session Border Controller (SBC) functionality. Some vendors also call internal “direct SIP” connections as “SIP Trunks”.


13

HP MSR Series at central site The HP MSR Series communicates with the Lync mediation server at the central site using the SIP protocol. Within the central site, the HP MSR router will typically be connected to the core switch via 1GbE RJ-45 or SFP. In this configuration, the HP MSR router may be performing other services, but the one we are focused on is voice with Microsoft Lync.

As shown in the diagram below, the HP MSR Series router provides the interface to the PSTN and local analog devices. Using SIP, the HP MSR Series router can communicate with the Microsoft Lync mediation server in TCP (less secure) or TLS (more secure) transport mode. The TLS transport mode is recommended for encryption of the SIP signalling and RTP media packets.

Figure 13: HP MSR Series as PSTN gateway at Lync central site

Since the central site will typically have a resilient Microsoft Lync infrastructure, there is no requirement for a Local Survivable Branch Appliance (SBA). In this manner, the HP MSR Series router provides voice PSTN gateway services for the Microsoft Lync central site.

• For additional scalability and/or resiliency, add a second HP MSR Series router as a PSTN gateway for the central site.


14

HP MSR Series at remote site/branch office At a branch office, an HP MSR Series router can provide PSTN gateway services and function as an enterprise router at the local branch location. At branch office locations where routing functionality is not required, the HP MSR Series router can provide PSTN gateway services only.

As shown in the diagram below, the HP MSR Series router at the branch communicates with the Microsoft Lync central site mediation server via the DMZ and Lync edge server. The HP MSR Series router at the branch office can use TCP or TLS transport mode, with TLS recommended for encryption of SIP siganling and RTP media packets across the WAN.

Figure 14: HP MSR Series at remote site/branch office

HP MSR as a PSTN gateway in a Lync topology To define an HP MSR Series router as a PSTN gateway in a Microsoft Lync environment, use Microsoft Lync Topology Builder to add an HP MSR Series router as a PSTN gateway.

• Configure HP MSR as a PSTN gateway • Use TCP or TLS

o Use port 5068 for TCP listening port on the Microsoft Lync server • Associate with Lync mediation server

Examples of configuring an HP MSR Series router in a Lync topology are illusted in the figure below.

Figure 15: HP MSR as a PSTN gateway in a Lymc topology


15

HP MSR as a PSTN gateway in a Lync dial plan To allow calls to be received from and sent to the HP MSR Series router PSTN gateway added to the topology, the Microsoft Lync Server Control Panel is used to configure routes, dial plan, call patterns, number substitutions and voice policies. With the appropriate dial plan configuration at the Microsoft Lync server, the HP MSR Series router can provide local PSTN access and enterprise-wide least cost routing services.

Examples of configuring an HP MSR Series router in a Lync topology are illusted in the figure below.

Figure 16: HP MSR Series in a Lync dial plan

HP Networking Reference Architecture for HP MSR as a Lync PSTN Gateway The HP MSR Series can be used as a PSTN gateway in a Microsoft Lync environment, which provides connectivity to the PSTN at any location connected via IP to the Microsoft Lync central server.

As shown in the diagram below, the HP MSR Series router can be deployed in branch offices from small to large, in different sizes of campus locations and also at the central site. Each of these locations have different scalability and resiliency requirements that can be met with different HP MSR Series router models. HP MSR voice SIC, MIM or FIC modules are added to the HP MSR Series router chassis to provide analog or digital voice connectivity to local analog devices, a local PBX/IP-PBX or to the PSTN.

Figure 17: HP Networking Reference Architecture for HP MSR as a Lync PSTN Gateway

HP MSR Voice Entity A voice entity on an MSR Series router is an object involving voice services, such as Plain Old Telephony Service (POTS) connections, Voice over IP (VoIP), Voice over Frame Relay (VoFR), or Integrated Voice Response (IVR).

POTS entities can be connected to Public Service Telephony Network (PSTN) subscriber lines or to FXS (sometimes FXO) analog device subscriber lines (analog phone, analog fax, analog speaker systems, etc.).

VoIP entities can be connected to IP Phones, other MSR Series routers, or other SIP proxy servers.

Voice entities are assigned a unique identifier (calling number) and pattern matching template. Voice entities include real objects such as MSR voice interface modules, analog phones connected to local MSR FXS ports, other MSR routers, or other SIP proxy servers or gateways.

HP MSR Voice Subscriber Line A voice subscriber line on an MSR Series router is an analog or digital telephony interface, such as FXO, FXS, T1, E1, BRI, and E&M.

A foreign exchange station (FXS) interface uses a standard RJ-11 connector and a telephone cable to directly connect with an ordinary telephone or a fax machine. An FXS interface accomplishes signaling exchange based on the level changes on the Tip/Ring line and provides ring, voltage, and dial tone.

A foreign exchange office (FXO) interface, namely, two-port loop trunk interface, uses a RJ-11 connector and a telephone cable to connect local calls to a public switched telephone network (PSTN) or PBX. Like an FXS interface, an FXO interface accomplishes signaling exchange based on the level changes on the Tip/Ring line. An FXO interface can be connected only to an FXS interface.

An ear & mouth or receive & transmit (E&M) interface uses a RJ-48 telephone cable to connect a PBX. The PBX sends signals on the M (M represents mouth) line and receives signals on the E (E represents ear) line. The voice router receives M signals from the PBX and sends E signals to the PBX. An E&M interface can only be connected to another E&M interface. When E&M is applied in VoIP communication, two or four voice wires can be used. In addition, there are two or four signaling wires. Therefore, 4-wire analog E&M actually has six wires. The 2-wire mode provides full duplex voice transmission and voice is transmitted in two directions on the two wires. The 4-wire mode is equivalent to the simplex mode and every two wires are responsible for the voice transmission in one direction.


25

A T1 interface can be physically divided into 24 timeslots numbered TS1 through TS24. o You may use a T1 interface as an ISDN PRI interface. The interface adopts DSS1 or

QSIG signaling. On the interface, except TS24 used as D channel for signaling, you may arbitrarily bundle other timeslots into an interface logically equivalent to an ISDN PRI interface.

o In addition to DSS1 and QSIG signaling, T1 interfaces support R2 signaling, digital E&M signaling, and LGS signaling. Configured with digital E&M signaling, a T1 interface is used as a digital E&M interface; with digital LGS signaling, a digital FXO or FXS interface.

An E1 interface is logically divided into timeslots (TSs) with TS16 being a signaling channel. o On E1 interfaces, you may create PRI groups or TS sets. o You may use an E1 interface as an ISDN PRI or CE1 interface: o As an ISDN PRI interface, the E1 interface adopts DSS1 or QSIG signaling. As TS0 is

used to transfer synchronization information and TS16 is used as a D channel to transfer connection signaling, you may arbitrarily bind any timeslots other than TS0 and TS16 as a logical interface, which is equivalent to an ISDN PRI interface.

o As a CE1 interface with a signaling channel, the E1 interface can adopt R2 signaling, digital E&M signaling, or digital LGS signaling.

HP MSR Dial Plan More requirements on dial plans arise with the wide application of VoIP. A desired dial plan should be flexible, reasonable and operable, and be able to help a voice gateway to manage numbers in a unified way, making number management more convenient and reasonable. The dial plan process on the calling side differs from that on the called side. The following discusses these two dial plan processes respectively.

On the calling side:

The voice gateway on the calling side replaces the calling and called numbers according to the number substitution rule on the receiving line.

The voice gateway performs global number substitution. The gateway selects a proper voice entity based on the voice entity selection priority rules

and replaces the calling and called numbers. The gateway initiates a call to the called side and sends the calling and called numbers.

On the called side:

After receiving a voice call (the called number), the voice gateway on the called side performs global calling/called number substitution.

The voice gateway on the called side selects proper voice entities based on the voice entity selection priority rules. (Number substitution may also be involved during the voice entity selection.) If the called party is a local voice subscriber, the gateway directly connects the subscriber line. If the called party is a PSTN subscriber, the gateway initiates a call and sends the calling and called numbers to the PSTN. The PBX in the PSTN connects the call.

HP MSR Regular Expressions You will frequently use some regular expressions when configuring number substitution rules. Regular expressions are a powerful and flexible tool for pattern matching and substitution. They are not restricted to a language or system and have been widely accepted. When using a regular expression, you need to construct a matching pattern according to certain rules, and then compare the matching pattern with the target object.

HP MSR Number Substitutions According to the network requirements, you can first configure a number substitution rule list, and then define specific number substitution rules, dot-match rules, and preferred number substitution rules for the list. Finally, you can apply these substitution rules globally or to voice entities and voice subscriber lines to substitute calling/called numbers flexibly. If there exists multiple number substitution rules in a number substitution rule list, only one number substitution rule will be matched. The match process is as follows:


26

The preferred number substitution rule is matched first. If the match succeeds, the gateway substitutes numbers on basis of this rule.

If the match fails, the gateway matches other number substitution rules in sequence. Once a rule is matched successfully, the gateway stops matching other number substitution rules.

HP MSR Call Services The MSR Series supports a set of voice call services for devices connected to local FXS ports only. The voice call services on the MSR Series of routers include:

Call waiting Call hold Call forwarding Call transfer Call backup Hunt group Call barring Message Waiting Indication Three Party Conference (requires VPM resources) IP-PBX Feature Codes
