Extension Lists
7. EXTENSION LISTS
7.1 An extension list is a group of intercom numbers or trunk numbers located on a single
node (off-node devices cannot be included in extension lists). These lists are used when pro-
gramming features that use common devices. For example, a group of phones could be
assigned to the same paging zone, have ring-in for the same trunk groups, and share common
toll restrictions. With an extension list, the programmer would have to enter only one extension
list number instead of repeatedly entering all of the station numbers for each list.
7.2 There are several types of extension lists:
• Agent ID: Includes only ACD hunt group Agent IDs. If no Agent IDs have been cre-
ated, this option cannot be used.
• Keyset: Includes only phone intercom numbers.
• Single-Line: Includes only single-line set intercom numbers.
• Stations: Include phone and/or single-line intercom numbers.
• Trunk Group: Includes only trunk group access numbers.
7.3 Station and Agent ID extension lists can be included in hunt groups. For example, a
hunt group can be programmed to send calls first to an individual station, then to an extension
list (where it rings all stations on the list), and then to another individual station or an extension
list.
7.4 The number of extension lists allowed on the system is determined by the number of
entries in the lists. There can be a combined total of up to 2500 entries (station or trunk exten-
sions) in all of the extension lists. (There can be up to 5000 entries in a triple- or quad-chassis
system.)
NOTE: When using an extension list for ring-in or hunt groups, do not exceed 30 stations per
list. The system can send ring signal to up to 30 stations.
7.5 In addition to the programmable extension lists, versions 7.0 and later system software
support two auto extension lists:
• PP051: Auto: All Stations
• PP052: Auto: All Keysets
7.6 When a station or voice mail application is equipped or unequipped, the system auto-
matically adds or removes that extension in the appropriate list(s). You cannot delete or renum-
ber the auto extension lists. You can only add or remove extensions from the lists in on-line
monitor mode (not recommended).
7.7 The two auto extension lists default with all existing stations and voice mail applica-
tions. In a default database, PP051: Auto: All Stations is assigned to Day/Night Outgoing
Access and Emergency Outgoing Access for the following:
• CO Trunk Groups
• Node Trunk Groups
• Node IP Connection Groups
NOTE: Extension list PP051: Auto: All Stations is assigned to Day/Night Outgoing Access for
version 7.0 and later default databases and newly created CO/Node Trunk Groups only. If you
convert an existing database to 7.0 or later, the extension list currently assigned to Day/Night
Outgoing Access (e.g., P0001) is used, not PP051.
