Lync Server 2010 and Verizon SIP Trunk

Topology

The procedures described in this document describe the following example scenario:

An enterprise has a deployed Lync server 2010 in its private network for enhanced communication within the company.

The enterprise decides to offer its employees Enterprise voice and to connect the company to the PSTN network using the Verizon SIP Trunking service.

AudioCodes Session Border Controller (SBC) is used to manage the connection between the Enterprise LAN and the Verizon SIP trunk.

The “session" refers to the real-time voice session using IP SIP signaling protocol.

The "border" refers to the IP to IP network border between the Microsoft Lync network in the Enterprise LAN and the Verizon SIP trunk in the public network.

Figure 1-1 below illustrates the interoperability topology between the Lync Server 2010

LAN and the Verizon SIP Trunking site.

The setup requirements are characterized as follows:

While the Lync Server 2010 environment is located on the Enterprise's Local Area

Network (LAN), the Verizon SIP Trunks are located on the WAN.

The internal data routing capabilities of the Mediant 1000 MSBG device are used.

Consequently, a separate WAN interface is configured in the LAN.

Lync Server 2010 works with the TLS transport type, while the Verizon SIP trunk works on the SIP over UDP transport type.

Transcoding support: Lync Server 2010 supports G.711A-law and G.711U-law coders, while the Verizon SIP Trunk also supports the G.729 coder type.

ATA - FAX Support via Analog Media Gateway.

Support for early media handling

Step 6: Configuring the Voice Coders

This step describes how to configure the Voice Coders. Since the Mediation Server supports both the G.711A-law and G .711U-law voice coders, while the Verizon SIP trunk supports the G.729 and G.711U-law coders, you can configure a single coder table reference for both services by utilizing the G711U-law coder as a single voice

coder (see Figure 3-20) or you can create a m ore dynamic servicing interworking

based on commonality of supported vocoders via the default Coders and Coders

Group tables (see Figure 3-19).

The Coder table is associated with the following IP Profiles:

IP Profile index 1 and 3 (see Section 3.8

on page

65 ) references ‘Coders Table’

(see Figure

3-19) which is associated with the IP Groups 1 and 3 (see Section 3.5

Step 9: Configuring Message Manipulation for Call

Forwarding

This step describes how to configure Message Manipulation for Call Forwarding.

To configure SBC Header Manipulation Rules:

1.

Open the Manipulation Table page (Configuration tab > VoIP menu > SBC >

Manipulations SBC

> Message).

Figure 3-24: Message Manipulations Table

2. Index #0

defines manipulation of calls to modify a header. For any request received modify the Header.Diversion.URL.host with ‘195.189.192.138’

3. Index #1

defines manipulation of calls to add a header. For any Invite request received and IF a Referred-by header exists, then Add the Diversion Header with what was received within the referred-by header, '<'+header.referred-by.URL+'>'.

Each of these rules bind to a specific Manipulation Set ID as represented within this table. Indexes 0 binds to Manipulation Set ID 0 and Index 1 is bound to Manipulation

Set ID 1.

Note the following:

Index 0

was created for a specific call scenario where a PSTN user originated a call on the Verizon SIP Trunk to an Lync 2010 DID, which has its DID forwarded to the PSTN as well as have its presentation Restricted in the Source number manipulation tables. This was set to change the Diversion URL host from

'anonymous.invalid' to ‘195.189.192.138’, which is the WAN address of the device.

Index 1

is utilized to dynamically capture the original dialed number for Lync DIDs and present them back to Sprint when a call is forwarded back to the PSTN when creating a Diversion Header. This functionality can only be used if Lync Server

2010 is set up to send Referred-by headers. This specific index creates a new

Diversion header for the call using what was presented in the Referred-by header, thus allowing the Verizon service to receive the original dialed DID extension that forwarded the call back to the PSTN SIP trunk.

Configuration Note 68 Document #: LTRT-31902

Configuration Note 3. Configuring AudioCodes Gateway

These newly created message manipulation sets can now be assigned for use. There are several methods to perform this function. One method is to assign the functionality to the entire application via the ini file or via the AdminPage.

This functionality is configured using the parameters

GWINBOUNDMANIPULATIONSET = [1] and GWOUTBOUNDMANIPULATIONSET =

[-1].

When using these parameter settings, the respective Manipulation Set ID is assigned for all inbound and outbound manipulations. When using the IP to IP application, such as in this example, the manipulation for inbound messages must be performed at the gateway level, so therefore set GWINBOUNDMANIPULATIONSET = 1. The outbound message manipulation can be performed either at the gateway level or more dynamically, at the IP Group level.

This section describes the following procedures:

Assign inbound manipulation to the entire gateway via the ini file or via the

AdminPage. See Section 0 below.

Assign outbound manipulation to a specific IP group index. See Section 3.9.2

below.

Assigning Inbound Message Manipulation Set to Entire

Gateway

This step describes how to assign a message manipulation set to the entire gateway via the INI file.

This assignment is configured using the parameters

GWINBOUNDMANIPULATIONSET = [1] and GWOUTBOUNDMANIPULATIONSET =

[-1]. These parameter settings are applied for all inbound and outbound manipulations respectively. For IP2IP applications, GWINBOUNDMANIPULATIONSET must be used for header manipulation requirements on incoming messages.

To assign inbound message manipulation set to gateway:

1.

Open the Admin page, by appending the case-sensitive suffix ‘AdminPage’ to the

Media gateway's IP address in your Web browser's URL field (e.g., http://10.15.9.118/AdminPage ).

2.

Step 11: Configuring IP-to-IP Routing Setup

The MSBG’s IP-to-IP call routing capabilities is performed in two stages:

Inbound IP Routing:

Recognizes the received call as an IP-to-IP call, based on the call's source IP address. This stage is configured in the 'Inbound IP Routing

Table'

Outbound IP Routing:

Once recognized as an IP-to-IP call in the first stage (see above), the call is routed to the appropriate destination (i.e., IP address). This stage is configured in the 'Outbound IP Routing Table'.

Configure Inbound IP Routing

This step defines how to configure the MSBG for routing inbound (i.e., received) IP-to-

IP calls to the Microsoft Lync network.

To configure in bound IP routing:
