Hi All, Can anybody help me by telling how to read INVITE packet SDP c line IP address in Kamailio.cfg. For example a INVITE packet comes and its SDP contains the line v=0 o=- 3619547086 3619547086 IN IP4 1.223.65.215 s=pjmedia c=IN IP4 1.223.65.215 t=0 0 a=X-nat:0 Now I want to read this SDP packet and want to put the IP 1.223.65.215 in a variable. Can anybody please help me out in this. Regards Varun
