Dialing
For generating an appropiate dial string, a conversion from canonical format may be required.
The following parameters determine the local settings of the phone, like
Local country code
or
Local national code
, and define rules for converting from canonical format to the format re-
quired by the PBX.
Data required
•
Local country code
: E.164 Country code, e.g. "49" for Germany, "44" for United Kingdom.
Maximum length: 5.
•
National prefix digit
: Prefix for national connections, e.g. "0" in Germany and United King-
dom. Maximum length: 5.
•
Local national code
: Local area code or city code, e.g. "89" for Munich, "20" for London.
Maximum length: 6.
•
Minimal local number length
: Minimum number of digits in a local PSTN number, e.g.
3335333 = 7 digits.
•
Local enterprise node
: Number of the company/PBX wherein the phone is residing. Max-
imum length: 10. (Optional)
•
PSTN access code
: Access code used for dialing out from a PBX to a PSTN. Maximum
length: 10. (Optional)
•
International access code
: International prefix used to dial to another country, e.g. "00"
in Germany and United Kingdom. Maximum length: 5.
•
Operator codes
: List of extension numbers for a connection to the operator. The numbers
entered here are not converted to canonical format. Maximum length: 50. (Optional)
•
Emergency numbers
: List of emergency numbers to be used for the phone. If there are
more than one numbers, they must be separated by commas. The numbers entered here
are not converted to canonical format. Maximum length: 50. (Optional)
•
Initial extension digits
/
Initial digits
: List of initial digits of all possible extensions in the
local enterprise network. When a call number could not be matched as a public network
number, the phone checks if it is part of the local enterprise network. This is done by com-
paring the first digit of the call number to the value(s) given here. If it matches, the call num-
ber is recognized as a local enterprise number and processed accordingly.
If, for instance, the extensions 3000-5999 are configured in the OpenScape Desk Phone
CP200/400/600, each number will start with 3, 4, or 5. Therefore, the digits to be entered
are 3, 4, 5.
•
Internal numbers
>
To enable the number conversion, all parameters not marked as optional must be
provided, and the canonical lookup settings must be configured (see Section 3.13.2,
“Canonical Dial Lookup”).
>
To enable the phone to discern internal numbers from external numbers, it is
crucial that a canonical lookup table is provided (Section 3.13.2, “Canonical
Dial Lookup”).
