Hello I am new with kamailio. here is my problem X-lite -->TLS-->Kamailio(TLS+RegisterForwrd)-->UDP-->RegisterServer-->PSTN/VOIPCall I am able to forward my register request to the register server, and make call. Able to talk from both side. But when i hangup the call from termination side call never hangup from origination side. I attached my config file. I got following log on my kamailio.log file ############# Jan 31 15:54:45 ser /usr/local/sbin/kamailio[7579]: DBG:tm:t_lookup_request: start searching: hash=53225, isACK=0 Jan 31 15:54:45 ser /usr/local/sbin/kamailio[7579]: DBG:tm:t_lookup_request: proceeding to pre-RFC3261 transaction matching Jan 31 15:54:45 ser /usr/local/sbin/kamailio[7579]: DBG:tm:t_lookup_request: no transaction found Jan 31 15:54:45 ser /usr/local/sbin/kamailio[7579]: DBG:tm:run_reqin_callbacks: trans=0xb61945d0, callback type 1, id 0 entered Jan 31 15:54:45 ser /usr/local/sbin/kamailio[7579]: DBG:core:mk_proxy: doing DNS lookup...
