Emne: Re: [Spce-user] Bye, Call-ID not found or tags didn't matche

Hi Sylvester,
could you please paste your /var/log/ngcp/rtp.log from beginning of the call until BYE?

Also this issue should be cosmetic only, i.e. the BYE message is processed and answered normally, but mediaproxy-ng does not delete the session, which times out after some time by itself anyway..
