We asked our provider about being able to break down long distance by local extension # on our bill. Right now it all shows up under our main PRI number on our phone bill.
When an extension with a DID calls outbound, it always pushes our Main number. We really didn't want our DID numbers to start showing up on client's call displays.
This is the response (below) from our PRI provider. Is there a setting in the UC520 to allow us to forward the extension number but not show the DID caller ID at the other end? (We setup and maintain the UC520 ourselves).
Thanks for any help!
Our systems are capable of providing the break down for you. Our telephone switching systems are slightly different from your previous provider however as we offer both options.
For this option, you will need to have your interconnect company program your PBX in order for us to capture the phone extensions (DID #s).
Your interconnect company would need to populate/activate the 'ANISP'
field on the PBX.
By having that option programmed, Allstream will be able to capture/bill
the LD calls by phone extensions instead of the main PRI #
The field is probably populated "CALLING PARTY NUMBER" right now instead
of "ANISP" and this is why the CPN is appearing on the invoice.
