Dear Ole

I am not finding any example how to do it (changing a fqdn with ipaddress in sdp).

Using sdp_get i can get the sdp.

But how i can use transformation function pls let me know.

The sdpops link does not give much info how to modify any line.

Best regards

austin

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.
