Hello,

Below you can find attached the 2 files of tcpdump

and for the logging I only see an error when it fails in this section where xlog("L_ERR","666666666666666") :

route[4] {

if (is_method("BYE|CANCEL")) { unforce_rtp_proxy(); } else if (is_method("INVITE")){ xlog("L_INFO","4444444444444444"); if (nat_uac_test("8")) { rtpproxy_offer(); #force_rtp_proxy(); } else { rtpproxy_offer(); #force_rtp_proxy(); } xlog("L_ERR","666666666666666"); t_on_failure("FAIL_ONE"); t_on_reply("REPLY_ONE");

};

if (isflagset(5)) search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes'); }

Regards

hi!

try to: - look in tcpdump of your SIP traffic (use wireshark) - add logging to your kamailio.cfg

both points to understand the difference between 2 calls (good and failed).

The description that you prepared is not informative enough - to understand what is wrong (important point: kamailio is sipproxy, and does not operate with such things as "call")

try to dig more, prepare more info on the point of view of SIP and share here.

cheers
