Hi ,

Sorry for the delayed reply.

I have configured my Asterisk and kamailio server, but when i initiate one outbound call from my asterisk server to kamailio server, kamailio server is initiating the call to MSC.

Please find the attached pcap details for your reference.

Below is my kamailio debug log and kamailio.cfg file.

Please check the pcap and below cfg file and log file and let me know whether to change anything in cfg file or not.
