If you register you ATA in a sip server you can route the call thru the
e164. You don't need any IP ADDRESS because you have the keepalive of your
registration.

Asunto: [cisco-voip] ata 186 using SIP

Hello,

Does anyone know how I can configure a ata186 behind a NAT router to 
make and receive calls thru a cisco gateway with a public IP address. I 
was able to make outgoing calls thru the ata 186 but I have a PRI on the 
gateway and  I would like to assign one of the DID numbers on the PRI to 
the Ata186. The ATA is behind a NAT router and the NAT router has a 
dynamic public IP on the internet side. I need a way for the ata to 
register on the cisco and sennd some kind of keepalive to indicate when 
its IP has changed.

Thanks in advance!
Edgar
