Cme 8.5 and 7940 phones

[alexten1983]

Hello every one.

Need some help with setting up a phone from remote location.

I have cme 8.5 ruining on public ip address. And i want to connect a phone to it from home (remote location). What do I need to do to allow phones to register to cme from public ip address and what do I need to do on the phone to point to that public ip address?
