3.1.8  

Group Call 
 
Implementing features, see also Manager E Group Call

Definition  
Incoming internal and external calls are signaled simultaneously to all the stations in a group. The group station to first answer the call is connected to the calling party. Subsequent calls are signaled at the remaining idle telephones/clients. If all group stations are busy, all group stations hear a call calling tone. The first station of the group to go on-hook will receive the waiting call.

Technical boundary conditions  
Any type of telephone can be used in a Group Call group. The telephones must be located in the same node. A telephone can also be located in another node, it will be registered from the system as a external telephone.
Each call group can be assigned a name in the database with 16 characters maximum.
Feature Interaction
A member of a group can activate DND. This means that the telephone will no longer ring when called through the Hunt Group number or when called directly.
Only display telephones can deactivate/activate Call Waiting Tone (#87/*87). They will not be signaled of a call waiting, but will receive a waiting call when they go on-hook.
Data Line security in Manager T (Call Waiting rejection in HiPath 3000/5000 Manager E) can be configured for a member telephone. An idle telephone rings when a call enters the group; however, a telephone is not advised of a call waiting, and if it goes on hook and calls are waiting, the telephone does not ring until a "new" call enters the queue.
Individual members of a group can Call forward-all calls on their telephones. With this feature active, the destination telephone becomes part of the group.
If station A calls a group, station B (group member) is authorized to initiate a call before or after the call from station A is signaled. If the call is initiated via the keyboard or a repdial key, a busy notice is displayed on station A's display and the call is signaled at another free group member. Station B hears a call waiting tone for the incoming call for all other ways for station B to initiate a call (e.g., repdial key external, call key, line key, redial key) unless station B activated DND. In this case a busy notice is displayed on station A's display and the call is signaled at another free group member.

Displays  
The display differentiates between internal and external calls and internal and external group members:
 •   Internal calls:At the calling party, the display shows the name of the group defined via Manager T (16-15-3) or HiPath 3000/5000 Manager E (Incoming Call -> Hunt Group -> Name).
   -   Internal group members: The internal group members with a display telephone see the name of the calling party: Call from: XXX.
   -   External group members: The external group members see the defined group name: Call for: GRP, Call from: XXX.
 •   External calls:
   -   Internal group members: The display of the internal group members shows the number of the calling party (as for a call with a single subscriber line): Call from: 1234.
   -   External group members: The external group members see the defined group name: Call for: GRP, Call from: 1234.

Dependencies/Restrictions  

 Subject  
 Dependency/Restriction  
External call forwarding  
If at least one subscriber in a group has activated external call forwarding, you cannot make an unscreened transfer within the group.  
Analog telephones  
The system does not check whether analog telephones are present. As a result, you must log the telephone onto the system by lifting the handset once.  
Intercept  
If the call cannot be signaled at any station, it is intercepted.  
Call waiting  
Busy stations receive call waiting or ring injection if no other stations are available.  
Join/Leave Group  
Each member of a group call can dial #85 to leave group call and *81 to reenter group call.  
Hunt group  
If a station is active in group call and a hunt group, any changes (such as dialing *85/#85) apply to both features.
