I have tried to summarize the SIP message flow below. I am also including

What might be causing VoipSwitch to send a BYE with ruri=acco...@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.
PS : Below is the SIP trace for the above call flow.
