OK, in first place you need to configure CME on your ISR (refer to the CME admin/config guide for any task), then, I'm assuming the other end supports SIP trunks, so you'll need to configure your SIP DPs to it. IP Phones dial DNs, not IPs.

Thanks let me try that. Firstly what is ISR?  Is it the router?  

[Jaime Valencia]

ISR = Integrated Services Router

You may want to ask this question in the appropriate section "Routing and Switching" since your question is related to NAT and not Cisco Voice.

Guys in the IP Telephony community have more knowledge in Cisco Voice and UC stuff than in Routing/NAT.
