4-14 Chapter 4Business Features PackageFlexible NumberingDefault system programming allows stations to have 3- or 4-digit extension numbersbeginning with the digit 2 or 3. Three-digit default extension numbers begin with 201 and 4-digit defaults begin with 2001. Station group numbers can be three or four digits beginningwith the digit 5. Other numbering plans can be used.Using digits other than 2, 3 or 5 will require the installer to change other feature accesscodes in the system default numbering plan. User guides will also need to be modified asthese are all written using the default numbering plan.Group ConferenceA programmed GCONF key can be used to automatically call a preset number and includethe called party in a conference when the call is answered. Up to five numbers, including thekeyset from which the conference is supervised, may be assigned to a conference group. Upto five conference groups can be assigned to an extension.Hot DeskingHot Desking gives users mobility by allowing them to locate to any selected station and,simply by dialling a code at the station, transfer all the features they normally require (aspecified extension number, pickup groups, paging groups, call barring, voice mailbox, andso on) to the station. This feature is also referred to as Set Relocation (see Station Features).Hot LineStations can be programmed to automatically call a pre-defined station or station groupwhenever that station goes off-hook. A hot line delay timer of 0–250 seconds can beprogrammed to allow sufficient time to make a different call, if required.In Group/Out of GroupIndividuals assigned to a station hunt group may temporarily remove their telephones fromthe group by pressing the In/Out of Group key, provided that there is someone still in thegroup. There is a system-wide option to allow all members to log out of a station group.Stations logged out of a group will not receive calls to that group but will continue to receivecalls to their individual extension numbers. When desired, the user can go back into thegroup by pressing the key again. Users who do not have this key may dial the access codeand the group desired. A station user is allowed to be in several groups, provided a key andthe extender for that group are assigned for each group on the user’s keyset.Incoming Call DistributionIncoming calls can be assigned to ring a distributed station hunt group. This allows allmembers of the group to share the call load.Incoming/Outgoing ServiceOutside lines are available for incoming or outgoing service. Programming allows any outsideline to be used for incoming calls only, outgoing calls only or both-way service.Individual Line ControlEach station in the system can be individually programmed to allow or deny dialling out aswell as allow or deny answering for each outside line.
