Is there anyway to test if the UA is from symmetric NAT?

Hi Chia,
You need to use STUN protocol for the detection of NAT type. The
detection must be done by the softphone.

The NAT detection must be done by the client, e.g. using STUN. If the
client detects symmetric NAT, it has to use the private IP in Via. Thus,
the proxy can detect that this client is unable of NAT traversal (using
the NAT checks from nathelper)
