Question about outbound caller ID.

[VOIPoJames]

For the majority yes Outbound CID will work, it's dependent on the rate center the number is through.

Is there a way to tell if it is available before I sign up and port or is it something of wait and see?

My original number ported from AT&T in Oklahoma to Viatalk. I would port from VT to Voipo..

Certainly just PM the NpaNxx and I can double check the rate center. If this number currently has Outbound CNAM then you're already in the clear (as in the rate center supports CNAM).
