No these phones do not use the "Unified" SIP package. The 79x1 series have a different SIP and SCCP package than the 79x0 phones. There config files are completely different also. They are the CiscoPlus phones. NAT is not working and I don't see anything on the net to get it working other than using MilkFish with DD-WRT. I'll just get some Polycom phones.

We have several 7960's working behind NAT (i use a 7960g) and a few with remote worker. We didn't have to set anything special. Make sure in the phone config you do not have set to use STUN or is not set with a "NAT Public IP". When it register is should append the "nat" to it. If you see "no-nat" then the phone is trying to compensate for the NAT. when we first setup a 7960 remote worker phone I fought with it until I found out the users dlink had a SIP aware gateway that was killing it. disabled and it worked fine. -M
