[VoiceOps] SIP calls that aren't torn down

[Frank Bulk]

I was speaking to a developer at Genband about our C15.  The softswitch was
built by TDM folk, with IP added on later.  I'm not surprised that there are
certain things mixing that would be assumed in a non-legacy product.

Is your softswitch from 1982? ;-)

OK OK I kid...  I am seriously curious what you're using though... These
are pretty standard in the open-source world and also on phones and
ATAs/media gateway hardware, etc.

Maybe you just aren't looking for the right option? Look for anything you
can configure known as a "timer" and kick back what you've got...
