I am trying to setup a UC540W-BRI-K9 with an "Anlagenanschluss" BRI in Germany. This Anlagenanschluss has a 100-number-block of public numbers assigned to it by the provider (1234.00 - 1234.99). When I enter this range in CCA, it says there were to many numbers. CCA accepts only 20 numbers.
Any idea how to properly setup this type of ISDN connection (Provider is QSC) ?
For outbound Calling number presentation, that is the absolute maximum if you use CCA. If you need to go beyond 15 individual DID's represented in the calling number when making outbound calls, then CLI is needed.
