Fig. 81 Routing to an internal destination via the allocation table
Configuration:
• Regions – Country code: 41
• Numbering plan – Exchange access, business: 0
• Entry in the allocation table:
– External call number: +41326553867
– Internal call number: 3867
A call to the following phone numbers is routed to internal destination 3867:
• 00326553867
• 00041326553867
Note:
Instead of Exchange access business, the digits for Exchange access private, Cost
centre selection or Route selection can also be used.
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.
