• If the phone number is not contained in the phone numbering list the PBX establishes an
external connection.
Internal phone: The user has to dial an external number with preceding exchange line
access number.
Direct exchange line phone: An external number requires no prefix. However, the user has
to dial an internal number with preceding **.
Notes: The behaviour of the COMfortel 1400 IP/2600IP/3200/3500/3600 IP phones when
dialling a phone number depends on the set default account (see manual of the phone).
For the COMfortel phones 1400 IP/2600 IP/3600 IP with firmware version 2.4 or later, the
default account, if the phone is system phone, can be taken over from the PBX and is thus
set depending from the exchange line request type.
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.
Also, when the entered phone number corresponds 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.
Emergency Calls
The emergency numbers set up on the PBX are used for emergency calls. These calls are
handled in a special way.
Note: One of the basic settings is the setting of the country where the PBX is located. By
this setting, the public emergency numbers of the selected country are automatically
entered in the configuration.
Emergency calls can be made without dialling an exchange line access number that is
necessary for other calls (factory setting). This has the benefit that even people who do not
know how to use exchange line access numbers can make emergency calls.
If the emergency call priority switch is enabled (factory setting), emergency calls have priority
over other calls. If necessary, a call can be interrupted to enable an emergency call to be
made.
A system phone can also be used to make emergency calls if the screen lock is switched on
(optional, see manual of the phone).
Installation
Warning: Power surges, which can occur during electrical storms, can cause life-
threatening electric shocks and can damage or destroy the PBX.
