I am using Kamailio 4.4. and calling the function sdp_remove_transport in order to remove some SRTP media lines.

The function works (of course!) however I would like to get access to the modified SDP within the cfg.

I thought this would do the trick:

sdp_remove_transport("RTP/SAVP");
sdp_get("$avp(foo)");
xlog("$avp(foo)");

However $avp(foo) does not contain the newly modified SDP.

Is there a way for me to access it? I have been looking at things like t_save_lumps() and msg_apply_changes().

Any pointers or confirmation that this is or isn't possible would be very welcome!

Thanks

Pete
