Thank you for your replies! Outbound calling is now completely working.
For incoming calls from SIP trunk to Teams there's still no ACK and CANCEL
messages. Which causes disconnect in 20 seconds and no audio.
I think there's something wrong with the routing or via headers in the 200
OK but don't know what.
The complete sip dump: https://paste.projectdev.org/imiluwecaf
Unfortunately i can't see the sip messages from the SIP provider side.
