[OpenSER-Users] Editing of SDP's?

Hm, my problem escalated a bit... Apparently... If I do this in my .cfg

if (has_body()){
	xlog("L_INFO","- body found");
}; 

It will only catch the INVITE. It won't catch the 200 OK message that comes
back from the gateway which contains the lines I need to alter...

I was thinking of simply doing a 
	replace_body_all("a=cdsc","i=cdsc");
To keep the same length etc of the SDP... However, I'm not getting that
option :-/

Any ideas?!
