Extension Numbering

The system can be configured to use either a 2 digit or 3 digit dial plan for user extensions.

For a 2 digit dial plan, the extensions are numbered 10 to 57. This numbering cannot be changed.

For a 3 digit dial plan, the extensions are numbered from 100 upwards. This numbering can be changed in the range 100 to 579 (the defaults are 100 to 199). In 2 digit mode only 48 extensions are supported, 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 assumes that the base control unit is always fully populated with up to 32 extensions, either real or phantom or a mix, to which it assigns extension numbers in sequence. It does this before assigning extension numbers to any real extensions on attached external expansion modules up to the system extension limit. If the system extension limit has not been exceeded, any remaining extension numbers are assigned to additional phantom extensions.
