Hello list. First of all sorry for dump question, i'm pretty new to kamailio so i hope someone point me in right direction currently i have one sip device which can handle sip request only from one ip, my goal is to put kamailio in front of it so i can proxy requests from several ips i added this to conf route{ if ( src_ip == 10.46.1.121 || src_ip == 10.46.1.122 ) { if(method == "INVITE") { $rd="10.46.29.10"; t_relay(); } } and calls seems connecting but signaling is completely broken i understand that i'm doing something wrong, but can't get what is wrong Please point me to solution Thanks
