Configuring the SIP proxy for network outage detection

When SIP traffic and WebSphere High Availability Manager traffic are not on the same networks, failures that affect SIP traffic might not be detected by the HA Manager, resulting in loss of SIP traffic. You can configure network outage detection on the same network as the SIP traffic to ensure that failures which affect SIP traffic can be detected by the HA manager.

About this task

Define these SIP proxy custom properties to set the network outage detection feature to ensure that SIP network failures are detected by the HA Manager.

Procedure

Results

The proxy will send keep alive messages to the server at the configured keep alive interval using the configured port and interface, which should be the same port and interface as those used for other SIP traffic between the proxy and the server.

If the proxy misses the number of responses configured as keepAliveFailures, or the server misses that number of keep alive requests, it will determine that SIP traffic should no longer be sent between the proxy and the server. The proxy will stop sending SIP messages to that server, and the server will restart and wait for connectivity to be restored before resuming operation.
