SIP service monitoring

Last published : Sep 24, 2026
A NetScaler has two built-in monitors that you can use to monitor SIP services: the SIP-UDP and SIP-TCP monitors. A SIP monitor periodically checks the SIP service to which the SIP monitor is bound, by sending SIP request methods to the SIP service. If the SIP service replies with a response code, the monitor marks the service as UP. If the SIP service does not respond, or responds incorrectly, it is marked as DOWN.
Parameter Specifies
sipURI SIP addressing schema of the SIP server.
sipmethod The type of SIP request used to probe the SIP service. Specify one of the following methods: INVITE, OPTION (the default), REGISTER
respcode SIP response code with which the SIP service responds the probe request. Default: 200.
