Hello list. I have a problem-question regarding to the BYE message reaching SER. For the normail example i have a endpoint registered in SER and a PSTN-Gateway receiving the outgoing traffic. For this enviroment when i made a call from my endpoint to the PSTN gateway and the Gateway send the BYE (at the end of the call) this is what i see in the debug in SER.
