Extension Numbering

IP Office Basic Edition systems can be configured to use either a 2-digit or 3-digit numbering for user extensions.

If 2-digit numbering is selected, the extensions are numbered 10 to 57. This numbering cannot be changed. In 2-digit mode only 48 extensions are supported.

If 3-digit numbering is selected, the extensions are numbered from 100 upwards. This numbering can be changed in the range 100 to 579 using system web management. In 3-digit mode a maximum of 100 extensions are supported.

In both cases, those extensions not matched by physical ports are automatically assigned as phantom extensions.

The system numbering mode can be changed through the phone based administration menus,
