Dear All When 200 OK to INVITE passes through Kamailio proxy , I want to change the IP address in SDP to a specific IP address.
Can this be done by just modifying configuration files or do I need to modify in source code.
In case I need to modify source code, which files I need to look at.
Kindly provide pointers for said problem.
You can modify ANYTHING in a text based attachment like an SDP in the configuration script. To make it a bit simple for you, we have two modules that work with specific parts:
- SDPops http://kamailio.org/docs/modules/devel/modules/sdpops.html - MANGLER http://kamailio.org/docs/modules/devel/modules/mangler.html
In the Mangler module there's a function called "sdp_mangle_ip()" that will make you happy.
You can always copy the whole SDP into an AVP with SDP_GET, use the transformations to read one line at a time and modify it.
