Determining the ports for a cluster of SIP Proxy/Registrars

In an IBM® Sametime® deployment, determine the port that the load balancer of IBM WebSphere® proxy server fronting a cluster of SIP Proxy/Registrars is listening on.

About this task

In a clustered environment, multiple SIP Proxy/Registrars are installed on separate nodes. Each set of nodes is clustered with a WebSphere Proxy servers deployed in front of the cluster to provide load balancing and failover. If you deploy two or more WebSphere proxy servers in front of the cluster, you must additionally deploy a load balancer to front the proxy servers.

For this task, you only need to check the ports used by the SIP Proxy/Registrar cluster. If a load balancer is in use, check its SIP ports; otherwise, check the WebSphere Proxy server's SIP ports.

Procedure

Load balancer:
  1. Check the port configured for SIP communications. and write down the value.

    Refer to your vendor documentation for information on configuring ports for the load balancer.

WebSphere proxy server:
  1. Log in to the WebSphere proxy server's Integrated Solutions Console as the WebSphere administrator.
  2. In the navigation tree, click Servers > Server Types > WebSphere proxy servers.
  3. In the table listing the proxy servers, click the name of the WebSphere proxy server that operates with the SIP Proxy/Registrar cluster.
  4. On the Configuration page, locate the "Communications" section and click Ports.
  5. In the Ports table, look for the port used by the SIP Proxy/Registrar, and write the value down:
    • If you are configuring TCP (unsecured) communications: PROXY_SIP_ADDRESS
    • If you are configuring TLS (secure) communications: PROXY_SIPS_ADDRESS
