Internal Telephone Numbers
Up to 32 internal telephone numbers for subscribers or line groups can be allocated on the
PBX.
Internal phone numbers must be configured for the internal ports so that the connected end
devices are accessible. Each connected end device receives a subscriber telephone number.
If multiple internal end devices need to be accessible via a telephone number, a common line
group for the internal subscribers must first be configured.
Note: It is a good idea to create a telephone numbering plan for the internal
telephone numbers before allocation and then use the following steps to
transmit this to the PBX.
Possible Types of Internal Telephone Numbers
Internal telephone numbers are taken from the internal telephone number plan. The following
types are possible:
• Telephone numbers for subscribers
• Telephone numbers for line groups
• Basis telephone number for call parking
• CAPI dial-in numbers
