Hi everyone,

I am still trying to find a solution to my problem with BYe messages that are not going through SER. Maybe someone with enough knowledge about route recording could help me with the configuration:

My main problem with BYE messages is that they are not going through SER; the client sends it directly to my rtp proxy. as the RTP is established with it. I need them to go through SER. How can I achieve this ?

I don't know how to use route recording, could you explain what following config block does ? (this is in the default configuration but doesn't make BYE messages to go through SER)

if (!method=="REGISTER") { record_route(); }

if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; };

thanks, ilker

Hi,

Thanks for your reply but this is totally a different case. In my case the problem is not CANCEL messages but BYE and ACK messages.

BYE message (and also ACK) is sent to the contact of the RTP stream instead of the SER proxy. But I want these messages to be sent to SER. That's why I should somehow make them to be sent to SER.

So It should be done by either recording route or changing contact header. How can I do that ?

Thanks, ilker

hi, i had that problem a time ago. I just put this messege and now it's working fine. if (method == "CANCEL" ) { if (uri =~"^sip:4[0-9]*@localhost") { forward ( asterisk , 5060 ); t_relay(); break; }; };

Hi, For voice communication I use a SIP+RTP proxy together with SER. For PSTN calls SER routes the INVITE messages to the RTP proxy. Everything works fine there, but when the call is ended by one client (which is connected to SER) or the PSTN user, the BYE message does not arrive to SER. If our RTP proxy does not see the message coming from SER, call doesn't end. That's why I need all of the BYE messages to go through SER. How can I do that ? In the default configuration there is a record route process for every message other than REGISTER. But still BYE and ACK messages are not sent to SER. Should I change the contact header of the messages arriving from RTP proxy ? If so, how can I do it ? What does following configuration block do ? if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; Thanks, ilker
