[cisco-voip] Asking the experts (Carrier to PBX Issues)

[Kevin Thorngren]

Not sure I have any answers for you but I do have some questions.....

Does this problem happen with every call?

Does it only happen when the call is originating from certain carriers?

How does the caller get in touch with your customer to ask if the 
phones are down?

What happens if you place an outbound call from your customer's site to 
one of your customer's phone numbers, i.e., hair pinning the call 
through your customer's carrier?

The carrier states they aren't seeing the calls in their switches.  If 
I understand the problem correctly this is saying that the customer's 
carrier is not receiving the call from the originating side.  Which 
means that the call won't be extended to your customer.  Am I 
understanding this correctly?

What does the carrier mean by "this never happened to us when we did 
the phone lines over PSTN"?  And how does this apply if they aren't 
receiving the call from the originating side?
