Internal call numbers

These are call numbers by which the connected extensions can call each other.

Each of the internal call numbers in the set can be assigned to one or more terminals. It is also possible to assign two internal call numbers to a terminal. In this way groups of extensions (on analog ports and on the internal S0 bus) can be reached by direct inward dialing at one internal number, such as for a hotline service, a call center or an order processing unit. Each user is also assigned a second dedicated number at which he or she can be reached directly.
