I'm having an issue with a local service provider and I was hoping someone could help out. The customer I'm working with wants individual extensions to be passed as the calling number for external calls. The extensions are masked with the area and exchange codes at the route level. The gateway is an MGCP gateway.
Now every time an outside local number is called it receives the main listed number as the Calling party number.
I can see, using debug isdn q931, that we are sending out the extension info and not the main listed number. However, the service provider insists that we are not sending them anything or that we are sending the main listed number.
Am I right in my assertion that the Called Part Number field of the q931 debug is the information we are sending? I personally think the service provider is full of it. But I want to make sure.
two things that possibly the telco wants to have different, perhaps they want the calling number to be your DID only, like 3 or 4 digits, let's say the same number of digits you receive for incoming calls. Then also check what plan/type they set for for incoming calls, so it can be set to be the same.
