Ascotel® IntelliGate® Net:
In an AIN with nodes in different countries the abbreviated dialling num-
bers must always include the international prefix (e.g. "00") and the coun-
try code (e.g. 41).
(example: 0-0041326553333). This is necessary as the national portion of
the number may well be identical in different countries. This prevents
conflicts in the call routing and call number display (CLIP).
Dialling the emergency number
Depending on the switch group and switch position, the emergency number dials
one of the three stored phone numbers. The phone numbers must have an ex-
change access prefix.
The external digit barring is bypassed.
The call is routed via the user’s route, provided the stored phone number does not
already have a prefix for exchange access with route selection.
The call charges are logged in accordance with the user configuration, provided
the stored number does not already have an exchange access prefix that regulates
call charge logging (e.g.
Exchange access, Private
).
Dialling from SIP terminal
For SIP terminals, the international number format beginning with the "+" sign is
supported (canonical number). The PBX changes the "+" to a "0" (
Exchange access,
Business)
. The external call number may also contain the following characters: "+", "/
", "(", ")" and "blank". These signs are filtered out by the PBX before dialling. If a call
number contains the country code as well as the national prefix, the national prefix
can also be automatically filtered out (see
"Dialling internal destinations via exter-
).
Dialling an external number assigned to an internal destination
If an external call number is assigned to an internal destination, the outgoing call
will be routed to the internal destination under certain conditions (see
