Does anybody have SER running with MEDIAPROXY and Vovida B2BUA at the same machine?
I'm having a little trouble with the calls: They are finishing after 30 seconds.
After I have reviewed the NGREP sniffing I can detect that the B2BUA is sending a BYE to the SER as you can see:

Only B2BUA can generate a BYE, so it's definitely not SER. However, there may be something else that causes Vovida to generate it. I would start in that end. I don't know Vovida, so I wouldn't know where to start... g-)

30 seconds calls are usually an ACK problem due to NAT. Make sure the callee receives the ACK.

Hi Klaus
I'm trying to do the following:
UA behind a NAT ----> SER+MEDIAPROXY --------> B2BUA -----> SER+MEDIAPROXY------> PSTN GATEWAY
The first callee is the UA behind the NAT and then the B2BUA calls to the PSTN. The B2BUA has a public IP address (isn't nated) The PSTN GATEWAY has a public IP address too.
I'm attaching the full NGREP sniffing from the call in order you can see all the flow.
Regards

The first strange thing is, that the 183 and 200 OK messages bypass the first proxy and the messages are sent directly from the B2BUA to the SIP client. Although the ACKs look fine.
And there is a problem with the BYE - you have a lot of retransmissions of the BYE from the B2BUA to the client - maybe a NAT problem?

Hi Klaus
I'm trying to do the following:
UA behind a NAT ----> SER+MEDIAPROXY --------> B2BUA -----> SER+MEDIAPROXY------> PSTN GATEWAY
The first callee is the UA behind the NAT and then the B2BUA calls to the PSTN. The B2BUA has a public IP address (isn't nated) The PSTN GATEWAY has a public IP address too.
I'm attaching the full NGREP sniffing from the call in order you can see all the flow.

30 seconds calls are usually an ACK problem due to NAT. Make sure the callee receives the ACK.

Only B2BUA can generate a BYE, so it's definitely not SER. However, there may be something else that causes Vovida to generate it. I would start in that end. I don't know Vovida, so I wouldn't know where to start... g-)

When the SER receives the call from the UA it forwards the call to the B2BUA it is because the B2BUA is replying directly the 183 and 200 ok messages (I guess).
The BYE retransmisions are due the B2BUA is sending the BYE with a different route: U 2005/06/26 23:00:05.104387 200.94.75.6:5065 -> 200.94.75.6:5060 BYE sip:018183324166@200.94.75.6:5060;lr=on SIP/2.0.

As you can see for some reason it is mixing the SER IP address with the UA rport.
I guess as this route doesn't exist it is because there are a lot of retransmissions.
I have the SER debug from this call too. I can sent you if it's necessary

The first strange thing is, that the 183 and 200 OK messages bypass the first proxy and the messages are sent directly from the B2BUA to the SIP client. Although the ACKs look fine.
And there is a problem with the BYE - you have a lot of retransmissions of the BYE from the B2BUA to the client - maybe a NAT problem?

Hi Klaus
I'm trying to do the following:
UA behind a NAT ----> SER+MEDIAPROXY --------> B2BUA -----> SER+MEDIAPROXY------> PSTN GATEWAY
The first callee is the UA behind the NAT and then the B2BUA calls to the PSTN. The B2BUA has a public IP address (isn't nated) The PSTN GATEWAY has a public IP address too.
I'm attaching the full NGREP sniffing from the call in order you can see all the flow.

30 seconds calls are usually an ACK problem due to NAT. Make sure the callee receives the ACK.

Hi Alberto,
I'm not sure how your B2BUA handle private IP in SDP (c=IN IP4 172.31.253.127) from the Linksys UA. The call flow is "fine" (see below) but the RTP packets is not going through your B2BUA. Normally, the B2BUA shall rewrite the SDP and carry the RTP packets. In you case, it's not doing so. The BYE might be sent out by the B2BUA because it does not receive any RTP packets from Linksys. Thus, it disconnect the call because it thinks the UA is not responding. Although the call is established, the RTP packets are between Linksys and Cisco. Please check your B2BUA configuration.
Also, as Klaus said, the call flow is a bit strange. The B2BUA is not relaying the 183 and 200 responses to SER than Linksys. I'm not sure why your Linksys is responding to these two responses from the B2BUA, it's definitely a problem for other NAT routers. I guess your Linksys do have the problem as it's not responding to the BYE request from B2BUA.

Hi Klaus
I'm trying to do the following:
UA behind a NAT ----> SER+MEDIAPROXY --------> B2BUA -----> SER+MEDIAPROXY------> PSTN GATEWAY
The first callee is the UA behind the NAT and then the B2BUA calls to the PSTN. The B2BUA has a public IP address (isn't nated) The PSTN GATEWAY has a public IP address too.
I'm attaching the full NGREP sniffing from the call in order you can see all the flow.

30 seconds calls are usually an ACK problem due to NAT.
Make sure the

I'm using VOVIDA B2BUA.
According with its man page it says the following: "B2bUa is in the call-signalling-path all the times. There are numerous applications in which b2bUa can be used either as a media negotiator or simply supervising the calls between two parties."
Its configuration file is very simple only have the following: <B2BUA_Configuration> <SIP> <Local> <Port>5065</Port> <Transport>UDP</Transport> </Local> <Proxy_Server> <Address>200.94.75.6</Address> <Port>5060</Port> </Proxy_Server> <Registration> <Register>no</Register> <Address>200.94.75.6</Address> <Port>5060</Port> <Expires>600</Expires> </Registration> </SIP> <RADIUS> <Local> <Authentication_Port>1812</Authentication_Port> <Accounting_Port>1813</Accounting_Port> </Local> <Billing_Server> <Address>200.94.75.11</Address> <Authentication_Port>1812</Authentication_Port> <Accounting_Port>1813</Accounting_Port> <Password>password</Password> </Billing_Server> </RADIUS> <PrePaid> <Billing> <Option>mandatory</Option> <Refresh_Time>20</Refresh_Time> <Extract_User_Id_From>Proxy-Authorization</Extract_User_Id_From> <User_Id_Decode_Scheme>Basic</User_Id_Decode_Scheme> </Billing> <Use_SIP_INFO>no</Use_SIP_INFO> <Use_HTTP>no</Use_HTTP> </PrePaid> <Redundancy /> </B2BUA_Configuration>
Regarding the NAT issue I have tested the Linksys with SER and MEDIAPROXY alone and I don't have any problem. I can have the call more than 1 hour and it stills alive.

Is it running out of credit? I'm not familiar with VOVIDA B2BUA but I remember there is some internal timer of 30s which trigger the BYE. You may ask people in the b2bua mailing list.
