I am a novice technician, so please bear with me if I miss something apparent.
I have a customer that can no longer dial internationally station-to-station after the installation of their MiVoice 250. Their Carrier is AT&T (PRI) and I have not heard anything back from them as to what they expect to get from our system to dial internationally, nor do I expect to at this point.
I have checked the dial rules and they appear to be correct. I have also checked that their outgoing trunk group is in the correct groups to dial out. The customer is stating they are getting a fast-busy signal when they attempt to dial.
Does anyone have any guidance on what Dial Rules I should be looking at with an AT&T PRI? Or if I should have my search begin elsewhere?
