1.3 Dial Plan
Extension Numbering
IP Office Essential Edition - Norstar Version systems can be configured to use either a 2 digit or 3 digit dial plan for user
extensions. The numbering choice is made either using the Tools | Extension Renumber 154 option or during creation of
an offline configuration 43 .
· 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 using the Tools | Extension Renumber 154 option (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
20 .
· The system assumes that the base control unit is always fully populated with up to 24 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.
