I'm using openser 1.0.1 with rtpproxy and nathelper. Calls are goin through with good audio. Hanging up is fine too. However I've noticed I've been getting errors in my logs: <br> <br> ERROR: extract_body: message body has length zero<br> ERROR: force_rtp_proxy2: can't extract body from the message<br> <br> I'm assuming I'm doin something wrong in my config but I dont know where. Can someone please point out my mistakes?
