[Asterisk-Users] Why is sip saying NO NAT

[Chris Mason (Lists)]

In the sip conversation below, the traffic is sent to the client and 
Asterisk is saying "noNAT"
However, this client is configured
nat=yes
qualify=yes
canreinvite=no
So why does it still say "noNAT"? The IP of the phone is 10.0.0.xx

Retransmitting #4 (no NAT) to 209.59.xx.xx:10979:
