Creating or Modifying a SIP Server Profile

Resource Manager includes an embedded SIP Back-to-Back User Agent (B2BUA) component for managing SIP traffic to network devices (such as to MCUs) which are managed by Resource Manager.

To enable Resource Manager to operate with SIP endpoints, configure Resource Manager with an external SIP server to which SIP endpoints are registered.

Procedure

---

Step 1 Click Resource Management in the sidebar menu.

Step 2 Click Gatekeeper/SIP server.

Step 3 Click the link in the Name column for the SIP server you require, or click Add to create a new SIP server profile.

Step 4 Enter the name and IP address or Fully Qualified Domain Name (FQDN) of the SIP server in the relevant fields.

Step 5 Select the SIP server model.

You can select Microsoft LCS or other third-party SIP servers. Resource Manager is interoperable with the following external SIP servers:

•Cisco Unified Communications Manager version 5.0 or later

•Microsoft Live Communications Server 2005 with Service Pack 1

•Broadsoft IPCentrix

Step 6 (Optional) If you select Other in the Model field, select SIP in the Protocol field.

Step 7 Select the device island to which the SIP server belongs from the Location list.

Each device island can have only one SIP server.

The Location field is visible only when the IP Topology tab is activated in the Resource Manager Configuration Tool under System Configuration > UI Settings.

Step 8 Enter the name of the SIP server in the SIP Domain field.

Step 9 (Optional) Enter the name of a preferred and an alternative DNS server in the relevant fields.

Step 10 Click OK to save your changes.

Configuring the MCU to Work in SIP Mode

Perform the following configuration steps in the MCU web user interface.

Procedure

---

Step 1 Under MCU > Protocols > SIP, select Enable SIP Protocol.

Step 2 Set the SIP server IP address as the IP address of Resource Manager.

Do not change the port number or the type (UDP/TCP). The default port is 5060 and type is UDP.

Step 3 If the external SIP server is LCS, select Using Microsoft LCS.

In this case, the type is always TCP.

Step 4 Select Treat as outbound proxy to set Resource Manager as the outbound proxy of the MCU that is working in SIP mode.

Step 5 Click Advanced SIP Settings.

Step 6 Select Use "Empty Invite" when sending messages to endpoints.

---

Note We recommend using an empty invite when dialing out to a SIP endpoint.

---

Step 7 Click OK to save your changes.

Step 8 On the external SIP server, define a routing rule that forwards all calls whose dialing strings begin with the Resource Manager meeting ID or service prefix to Resource Manager.

The embedded SIP B2BUA can then forward the call to the appropriate MCU conference.

---

Note The default signalling port of the external SIP server is 5060.
