Use the transformation to get the number of lines in the avp, use a while loop and pick out each line, do the changes if needed. When you are done, use the set_body() function in the textops module to add the new SDP to the message. In the textops you also have a function named replace_body_stonce() that can do the trick for you. In short, there are many ways to do it, but you will have to read documentation :-)</div><div><br></div><div><a href="http://kamailio.org/docs/modules/3.3.x/modules_k/textops.html#id2498509">http://kamailio.org/docs/modules/3.3.x/modules_k/textops.html#id2498509</a></div><div><br></div><div>/O</div><div><br></div><div>----</div><div>Get updated!

</div></div><div class="HOEnZb"><div class="h5">You can modify ANYTHING in a text based attachment like an SDP in the configuration script.<br>
To make it a bit simple for you, we have two modules that work with specific parts:<br>
<br>
- SDPops <a href="http://kamailio.org/docs/modules/devel/modules/sdpops.html" target="_blank">http://kamailio.org/docs/modules/devel/modules/sdpops.html</a><br>
- MANGLER <a href="http://kamailio.org/docs/modules/devel/modules/mangler.html" target="_blank">http://kamailio.org/docs/modules/devel/modules/mangler.html</a><br>
<br>
In the Mangler module there's a function called "sdp_mangle_ip()" that will make you happy.<br>
<br>
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.<br>
<br>
