Ok, "bananas" might not be the right word, but it resembles what is
happening ;-)
When I get a CANCEL from my customer to Kamailio, it is not passed on
to my vendor - this is with a specific customer using VoipSwitch. The
result is that the phone called keeps ringing even though it's been
(attempted) cancelled, and a sideeffect is that it goes nuts at the
carrier side because it can send anymore and returns 480 or 486. Below
is the dialog from the Session Progress to when the call is cancelled
- and then it goes bananas.
Any ideas?
Thanks a lot!
