For the sdp cleanup purpose ( if possibilities of rrpengine are not enough) I use the next technic: - Set up write_avp param for the rtpengine module - call rtpengine manage: handled sdp will be then posted to write_avp pvar. - use lua/python/etc to call via lua_run(...) (this is for lua ) - handle value of write_avp there - apply the value to body of the message.
