Exchange Line Request Types and Notes
When dialling phone numbers, the exchange line request type configured for the subscriber must be noted. The PBX distinguishes three types of exchange line requests:
Internal phone: The user has to dial an external number with preceding exchange line access number.
Direct exchange line phone: For an external number no prefix is required. However, the user has to dial an internal number with preceding **.
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.
* Note: The behaviour of the phones COMfortel 1400 IP/2600 IP/3200/3500/3600 IP when dialling phone numbers depends on the configured default account (see manual of the phone). With the phones COMfortel 1400 IP/2600 IP/3600 IP as of firmware 2.4 the default account can be configured depending on the exchange line request type.
* Note: 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.
* Note: To avoid conflicts between 3 or 4 digit phone numbers of the local area network and the internal numbering plan, phone numbers of the local area network should always be dialled with local area code. In countries where external numbers can overlap with internal numbers, you can use the function "Force public exchange call with automatic exchange line request".
* Note: 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 the internal phone number. To avoid waiting time, you can subsequently enter #. The PBX therefore recognises the input as finished and instantly starts dialling.
