Yes, NAT1 and NAT2 are short for National-1 and National-2.  Cisco (and some others) call it NI which is short for National ISDN.

So, you are right on track that you would select NI-2 for the telco's NAT-2.

Thanks Matt.  Yes all our GWs with a PRI have NI2 as the PRI Protocol Type, and that was my first thought, but since NAT2 wasn't a option in the dropdown, I began looking elsewhere.  So when Verizon says NAT2 that means NI2 in CCM?

Thanks

You will want NI2, NI1 is not an option with Cisco gateways (surprised they are even willing to offer it, it's quite antiquated)..

This is selected through the PRI protocol however, not through Call Routing information.

Greetings,

We're putting in a Verizon PRI at one of our offices.  They're asking what Protocol we want, NAT1, NAT2, or custom.  I believe this has to do with caller ID, and that "NAT" stands for National.  Any insight into what I should choose?

On our existing gateways with PRIs, the dropdowns in Call Routing Information where I could choose "National" we have chosen "Cisco Call Manager."

Thanks
jeff
