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:
ERROR: extract_body: message body has length zero
ERROR: force_rtp_proxy2: can't extract body from the message
I'm assuming I'm doin something wrong in my config but I dont know where. Can someone please point out my mistakes? Thank you
