I can’t say how many times I had to configure SIP on Cisco voice gateways, troubleshoot SIP, enable SIP, etc.
The second problem, after fear of loading and stuck the router using the “debug ccsip messages” command, is to filter and find the call in debugging turned on.
If there is a way to collect all sip logs from the console or Syslog, we can use TranslatorX. Download it from here.
TranslatorX allows us to parse trace files and search calls and messages, create diagrams.
Note: it is NOT a Cisco TAC-supported tool, but very helpful.
