[VoiceOps] SIP calls that aren't torn down

[Frank Bulk]

Over the last few months our softswitch has accumulated 10 "stuck" calls
where there's no media traffic.  From what the softswitch vendor can tell or
guess, it just didn't receive a BYE to tear down the call.

We know that most SIP traffic on 5060 is UDP, and UDP is connectionless.
How are other vendors and systems managing such scenarios?  I suggested a
"no media" test where after x hours of no media, to tear down the call and
log the info.

Thoughts?
