Re: [Kamailio-Users] BYE message not relayed to caller

Daniel, I have tried to summarize the SIP message flow below. I am also including the entire SIP trace at the end of this message. Cell Phone Kamailio Phone B | | | |INVITE | | |------------->| | |100 Trying | | |<-------------| | | |INVITE | | |------------->| | |100 trying | | |<-------------| | |183SessionProg| | |<-------------| |183SessionProg| | |<-------------| | | | 200 OK | | 200 OK |<-------------| |<-------------| | | ACK | | |------------->| | | | ACK | | |------------->| |200 OK | | |<-------------| | | | BYE | | |<-------------|<- BYE,RURI=account@VoipSwitch | | BYE | | |------------->| | | BYE | | |------------->| What might be causing VoipSwitch to send a BYE with RURI=account@VoipSwitch? As a result the BYE message never gets forwarded to the cellphone, and the proxy repeatedly sends BYE messages back to VoipSwitch. Thanks in advance for your help. Regards, Vikram.
