If NAT is disabled, the port number shows in the Via and Contact SIP headers of SIP messages. If NAT is
enabled, the phone uses the NAT port number (and NAT IP address) in the Via and Contact SIP headers
of SIP messages, but still use the configured source port.
The following table lists the parameters you can use to configure SIP port and TLS port.
