Restrictions:
• Dialling from analogue terminals is not possible.
• Dialling from the system phone, ISDN terminal, SIP terminal or PISN user must be
done using bloc dialling. En-bloc means that the complete number is sent to the
communication server in one go. This is the case when dialling from a memory
(call list, repeat dial register, phone book etc.) or with call preparation via the
keypad.
• Permissible internal destinations: Internal users, User groups, Call distribution el-
ements and PISN users.
• In the allocation table external call numbers are to be entered in canonical for-
mat (starting with "+" followed by the country code). Several entries with identi-
cal external call numbers are not permitted. Multiple internal destinations, how-
ever, are permitted.
Special case of the integrated mobile phone:
When dialling from an integrated mobile phone, the call number is sent sequen-
tially by means of DTMF signals. In this case a 4-second timer is started after each
digit. Comparison with the entries in the allocation table is carried out only after
the timer expires or when the dial completion sign (#) is recognized.
Supporting the canonical number format
The international number format beginning with the "+" sign is supported (canoni-
cal number) for DSI system phones, IP system phones, SIP terminals and integrated
mobile phones. This enables, for example, SIP-based dual mode terminals (WLAN/
mobile) with the same stored number, depending on the mode, to reach a user via
mobile network (external) or via WLAN (internal). The following behaviour applies
to these terminals:
• The communication server changes the "+" to a "0" (
Exchange access business)
.
