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 :

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.

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,
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

Daniel,
Thank you for your response. Please find below the sip trace from INVITE
to BYE. These SIP messages were captured at the input interface of the
proxy, so the SDP is not rewritten yet.

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,
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 :

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.

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.

Vikram.

Hello,
In the Call flow diagram Phone B is to be read as VoipSwitch.
Regards,
Vikram.
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.

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.

There is
some mistake done somewhere in the routing elements. The sip
trace will help to identify where.

Hello,
In the Call flow diagram Phone B is to be read as VoipSwitch.
ignore previous email, I read that first and replied immediately ...
From the sip trace, the INVITE going to B has good record-route and
contact header. Therefore looks to be a bug in voipswitch.

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.

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.
PS : Below is the SIP trace for the above call flow.

Daniel,
Thank you for your response.
We have verified that it is indeed a bug with VoipSwitch. We uninstalled
the older version (v2.0.0965) of VoipSwitch that we were running and
replaced it with a newer version (v2.985), and the problem went away.
Once again, thank you very much for your assistance.
Regards,
Vikram.

Hello,
In the Call flow diagram Phone B is to be read as VoipSwitch.
ignore previous email, I read that first and replied immediately ...
From the sip trace, the INVITE going to B has good record-route and
contact header. Therefore looks to be a bug in voipswitch.
Daniel
Regards,
Vikram.

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.

New subject: BYE message not relayed to caller

Daniel,
Thank you for your response.
We have verified that it is indeed a bug with VoipSwitch. We uninstalled
the older version (v2.0.0965) of VoipSwitch that we were running and
replaced it with a newer version (v2.985), and the problem went away.
Once again, thank you very much for your assistance.
Regards,
Vikram.
Did you ever find a work around on this issue? We are getting 183 session
progress messages when going from voip to pstn. Did using v 2.985 fix this?

Hello,
In the Call flow diagram Phone B is to be read as VoipSwitch.
ignore previous email, I read that first and replied immediately ...
From the sip trace, the INVITE going to B has good record-route and
contact header. Therefore looks to be a bug in voipswitch.
Daniel

Vikram.

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.

What might be causing VoipSwitch
Which one is the voipswitch in the diagram above? You refer to it but
not included in diagram.
Daniel
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.
PS : Below is the SIP trace for the above call flow.
