Setting PRI Calling Numbers
A PRI Calling Number Setting in the bottom half of the Protocol Configuration dialog box
lets you set the numbers you want your Carrier to accept.
Figure 16. PRI Calling Number Setting
Most PRI trunks allow an AltiServ system to send calling numbers. For example, 10
different extensions in the same PBX system have 10 different DID numbers. With the
calling number feature provided by Carriers, the callee will receive a more accurate caller
ID.
PRI Calling Number can also be used in a mobile extension or IP hop-off to PRI trunk, so
the callee can receive a more accurate caller ID.
When a PRI span is subscribed, a block of DID numbers will be provided by the Carrier.
The Carrier should be able to accept Calling Numbers in the DID number block. However,
if the numbers are not in the blocks or the digit lengths are mismatched, the Carrier
might "reject" the call.
The
PRI Calling Number Setting addresses this issue. Choose from three options:
•
Carrier can accept anything as Calling Number (default)
•
Carrier can only accept Calling Number with a minimum of n digits
•
Carrier can accept only assigned numbers as the Calling Number.
If you select the third option, specify “assigned numbers” by clicking the Add button and
entering the numbers. To edit or delete a number you added, select it and click the Edit
or Delete button.
