> While troubleshooting another issue, came across this message in the debug log:

> [2012-11-25 19:07:25] DEBUG[13375][C-00000007]: chan_sip.c:17910 check_via: NAT detected for 216.115.69.144:0 / 216.115.69.144:5060
> Sending to 216.115.69.144:5060 (NAT)
> {noformat}
> Upon looking at the code in check_via, I discovered that if the port is not set on the address in the VIA header, the default SIP port is not being set on the tmp ast_sockaddr used to check if the requesting UA might be behind NAT.
