[Greger V. Teigre]

Don't call force_rport and fix_nated_register for this UA. Use 
if(search("^User-Agent: Cisco-CP7940G"))

I think because SER is replying to a the port (50650) that the REGISTER request came from, but the phone is not listening on port 50650. The phone never adds Digest Auth stuff into the REGISTER message, so I think its not getting the 401 Unauthorized message.
