I have one full 23 line PRI
What specifically should I be asking my provider?
- do you allow sending out Caller ID that does not ride/belong to that circuit.
Yes, you could ask them that.
Or, how do you dictate what outbound caller id is sent out from deskphones now? From within the Users and Services form or one of the other methods?
Try manually programming your extension to give off a phone number that wouldn't belong to the company, and see what happens when you call your cell from you desk phone.
