Hello,
can you post the entire call flow, from initial invite to to the bye.
There is some mistake done somewhere in the routing elements. The sip
trace will help to identify where.
Cheers,
Daniel

Hello,
I also want to add that, this behavior is not seen while using Asterisk
instead of VOIPSwitch. While using Asterisk, the BYE message has a request
URI corresponding to the cellphone, so the proxy forwards the BYE message
to the cellphone which causes the cellphone to hang up.
Thanks in advance for your help,
Vikram.

Hello,
My setup includes a cellphone that uses Wi-Fi to hookup to the internet
with IP 192.168.1.101. Cellphone app, tries to register with VOIPSwitch
through an outbound proxy server(Kamailio + rtpproxy), which rewrites SDP
to force rtp through an rtpproxy.
I can make a call from the cellphone to a PSTN number. When the PSTN
endpoint hangs up, VOIPSwitch relays a BYE message to the proxy that looks
like :
No. Time Source Destination Protocol
Info
27 18.383929 IPaddr_VoipSwitch IPaddr_proxy SIP
Request: BYE sip:1234@IPaddr_VoipSwitch
Frame 27 (420 bytes on wire, 420 bytes captured)

To: "1234"
<sip:1234@IPaddr_VoipSwitch>;tag=9XHJmiuf58vTrF7.vwflEK-G63JVPQSi
Content-Length: 0
The request URI in the above message is the IP address of VOIPSwitch
itself, which causes the proxy to forward the BYE message back to
VOIPSwitch. The cellphone never receives the BYE message and consequently
never hangs up.
Any suggestions on how i can get around this problem ?
Thanks and Regards,
Vikram.
