Error: The received SIP Message is not as long as the Content-Length specified.

Karl

I have an Axon 1.20 server, 5 expresstalk clients and an Intertex IX-67 SIP router.

The IX-67 is totally SIP transparent and claims to be fully compatible. I am running the latest firmware for the router. We have never has any SIP issues with this router before, so I doubt the router is at fault here.

Whenever I try to make a SIP call, the guy on the other side can't hear me, but I can hear them. The router SIP logs say:

Recv 4 bytes from 192.168.0.101, socket 21

The received SIP Message is not as long as the Content-Length specified.

Invalid data received at SIP port

Parse error at '' in message from 192.168.0.101, at line:

192.168.0.101 is my Axon server. Is this a bug in Axon? Line 2 in the error message would suggest something is wrong with the package headers?

Edit: Upon further inspection this seems to have something to do with STUN keepalive packets. Are they malformed somehow?

Karl

I'm an idiot and the call problems were related to an incorrect outbound proxy. I still think there might be a problem with the STUN packets, though.
