Note: The short code number is a part of the internal dial plan and is therefore an internal number. However it leads to an external connection.

Note: In order that the distinction between internal numbers and phone numbers in the local area network functions, the internal dial plan must not contain phone numbers that also occur within the local area network. To avoid conflicts, phone numbers of the local area network should always be dialled with local area code.

Note: Also when the entered phone number correspond with the internal dial plan, the PBX waits up to 4 seconds for whether additional digits for an external number are being entered, before it dials the internal phone number. To avoid waiting time, you can subsequently enter #. The PBX therefore recognises the input as finished and instantly starts dialling.

Note: In factory settings, the system-wide automatic exchange line request (for all subscribers) is switched on. Alternatively, the exchange line request type can be set separately for each subscriber. In this case, the automatic exchange line request can only be selected for IP DECT phones, COMfortel 1200 IP and COMfortel C-400. For all other subscribers, only direct exchange line phone and internal phone can be selected.
