Re: [Users] ERROR: extract_body: message body has length zero

Hello,

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

you call force_rtp_proxy() for messages which have no SDP body. Using search() or pseudo-variables you can check if content length is > 0 and content type is application/sdp. The error is harmless, just fills the log files.

Cheers, Daniel

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
