[asterisk-users] Cisco 7960 Double Natted

[Barry Fawthrop]

Thanks for the input
Yes I have nat=yes and qualify=yes  I know in the SIP<MacAddress>.cnf  file
I have

# NAT/Firewall Traversal
nat_enable: 1
nat_received_processing: 1
nat_address:  phone's public IP Address

Do I still need to set it again in SIP Configuration ?

Thanks all
Barry
