Hello. I think there is a problen with your configuration file. You have :
if (method=="INVITE") || (method=="CANCEL") { # Uncomment this if you want to use digest authentication if (!radius_www_authorize("")) { www_challenge("", "0"); break; };
record_route(); rewritehostport("cisco_sip_gw_ip:5060"); if (!t_relay()) { sl_reply_error(); }; break; };
so you're not relaying all the SIP messages, maybe this can work :
if (method=="INVITE") || (method=="CANCEL") { # Uncomment this if you want to use digest authentication if (!radius_www_authorize("")) { www_challenge("", "0"); break; }; };
record_route(); rewritehostport("cisco_sip_gw_ip:5060");
if (!t_relay()) { sl_reply_error(); break; };
Hope this work. Good luck.!!

Hi All,
I have a serious problem with SIP call flow over SER. My SER don't retransmit ACK first and after that don't retransmit BYE message, too. Can any one advice me? what can be a reason? Here are call flow and ser.cfg.
