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) Ethernet II, Src: Unispher_40:b5:39 (00:90:1a:40:b5:39), Dst: Supermic_bd:b9:bc (00:30:48:bd:b9:bc) Internet Protocol, Src: IPaddr_VoipSwitch , Dst: IPaddr_proxy User Datagram Protocol, Src Port: sip (5060), Dst Port: 7160 (7160) Session Initiation Protocol Request-Line: BYE sip:1234@IPaddr_VoipSwitch SIP/2.0 Method: BYE [Resent Packet: False] Message Header Route: <sip:IPaddr_proxy:7160;lr=on;nat=yes> CSeq: 1 BYE Via: SIP/2.0/UDP IPaddr_VoipSwitch:5060; branch=z9hG4bk180242100434182912333954 From: sip:5678@IPaddr_VoipSwitch;tag=18024210041929123187506289 Call-ID: LUOyIDm-ecy36NcUfj5G3v1lM6g5snkM 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.

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 On 02/18/2010 12:48 AM, Vikram Ragukumar wrote:

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 :
No. Time Source Destination Protocol Info 27 18.383929 IPaddr_VoipSwitch IPaddr_proxy SIP Request: BYE sip:1234@IPaddr_VoipSwitch

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.

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.

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

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

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

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

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,

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.
