Unable to make outbound calls to SIP endpoints
In
cases where no SIP calls can be completed, the SIP server may not be reachable from the
Secure Router 2330/4134. Use the ping command to verify that the Secure Router 2330/4134
Media Gateway can communicate with the SIP server.
Also, if the SIP server is configured with FQDN, then verify whether the FQDN can be resolved.
Be sure that the DNS server is specified on the Secure Router 2330/4134 using the ip
pname_server command.
There are several other potential sources of call failures. You can debug many of these issues
with information provided by routing traces.
To enable routing traces, enter the debug voice cc routing command
Neither SIP server nor VoIP dial peer are configured
If neither the SIP server or VoIP dial peer are configured on the Secure Router 2330/4134,
then no calls can be routed to the SIP network.
