Supporting the canonical number format
For AD2 system, SIP terminals and integrated GSM terminals, the international
number format beginning with the "+" sign is supported (canonical number). This
enables, for example, SIP-based dual mode terminals (WLAN/GSM) with the same
stored number, depending on the mode, to reach a user via GSM network (exter-
nal) or via WLAN (internal). The following behaviour applies to these terminals:
•
The PBX changes the "+" to a "0" (
Exchange access, Business)
.
•
Sometimes call numbers are given the following signs for better readability: "-",
"/", "(", ")" 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 na-
tional prefix can also be automatically filtered out. To do that, the digits in the
List of countries
(CM_1_2_12) have to be entered.
Example:
Entry in country list:
Country code
: +41,
National prefix
: 0
Call n41 (0)32 655 3867 and +41 (032) 655 3867 are converted to
+41326553867.
Covering number ranges
By using one or more placeholders in the allocation table, entire number ranges
can be covered with one entry.
