trunk Asterisk SVN-branch-1.8-r313860M and "User-Agent: Cisco-CP7940G/8.0"
also get the same as jmls and wdoekes if the following isn't set.

in SIP001234567890.cnf (probably could have been in SIPDefault.cnf)<pre>
# NAT/Firewall Traversal
nat_enable: "1"
nat_address: ""
voip_control_port: "5060"
start_media_port: "16384"
end_media_port:  "32766"
nat_received_processing: "1"</pre>

without the above I get
tcpdump: of failed register
20:43:50.392816 IP 192.168.124.63.50367 > 192.168.5.40.5060: SIP, length:

with the above in the provisioning.
