Microsoft Lync and ThinkTel SIP Trunk 4. Configuring the E-SBC Device

4.3 Step 3: Configuring Signaling Routing Domains

This step describes how to configure Signaling Routing Domain. A Signaling Routing

Domain (SRD) is a set of definitions comprising IP interfaces, device resources, SIP

behaviors and media realms. Together, these create virtual multi-service gateways from a

single physical device. Once configured, the SRD can be assigned to an IP Group and to a

Proxy Set

4.3.1 Configuring Media Realms

A Media Realm represents a set of ports, associated with an IP interface, that are used by

the E-SBC to transmit or receive media (RTP or SRTP). Media Realms are associated with

SRDs or IP Groups.

The simplest configuration is to create one Media Realm for internal traffic and another for

external (internet-facing) traffic.

Figure 4-6: Media Realm Table

¾ To configure an Internal Media Realm:

1. Open the SIP Media Realm Table page (Configuration > VoIP > Media > Media

Realm Configuration).

2. Click Add.

3. In the 'Index' field, enter 1.

4. In the 'Media Realm Name' field, enter a name (e.g. LanRealm).

5. In the 'IPv4 Interface Name' field, select interface name Voice.

6. In the 'Port Range Start' field, enter a number that represents the lowest UDP port

number that will be used for media in the LAN (e.g., 6000).

7. In the 'Number of Media Session Legs' field, define the number of media sessions that

are assigned with the port range (e.g., 10).
