[SR-Users] BYE issue kamailio + rtpproxy "481 call leg transaction doesn't exists".

[Daniel-Constantin Mierla]

Hello,

are you using topoh module?

A pcap with all sip messages part of the dialog, from the initial INVITE
to the last BYE transaction would be important to have in order to
investigate how the headers are changed.

Cheers,
Daniel
