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.
