SPA504G: Syslog-Msg [0]CC:NewCallState 0/9

wallmeier · ‎10-10-2011

Hello!

during a phone call I see several syslog message of the form

[0]CC:NewCallState 0/9

Which call states does exist? I would expect the number inside the brackets encode somehow the used extension and the line - but how? Or does it encode something completely different?

Thanks in advance!

Hi Dan,

Nice work on putting together the call states table. I ran your table past a development engineer and they said that the [x] in the [x]CC:NewCallState M/N syslog/debug output "is the call appearance index and is useful for when development engineering is tracing the call object".

Patrick---
