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) ?
