Exchange Line Request
The PBX distinguishes three types of exchange line requests:

Automatic exchange line request
(factory setting): Neither for the internal
nor for the external number a prefix is required (exception: ** for targeted
VoIP access). The PBX automatically distinguishes between internal and
external numbers with the adjustment of the dialled phone number and the
internal numbering plan:
•
If the phone number is contained in the phone numbering list, the PBX
establishes an internal connection.
•
If the phone number is not contained in the phone numbering list, the
PBX establishes an external connection.
Notes:
The short code number is a part of the internal numbering plan and is
therefore an internal number. However it leads to an external
connection.

numbers in the local area network functions, the internal numbering 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.
Also when the entered phone number correspond with the internal
phone numbering plan, the PBX waits up to 4 seconds for whether
additional digits for an external number are being entered, before it dials
