Calling Group Options

Calling Group Type

The Group Type setting determines whether or not the system automatically logs in members of a calling group following a power failure. The setting also determines the type of VMI when the calling group is used to connect voice messaging systems or automated attendant applications.

The following settings are available:

• Auto Logout. This setting is used to specify that the system does not automatically log in calling group members after a power failure. When the Group Type is set to Auto Logout (the factory setting) and a call sent to a calling group member is not answered within 30 seconds (5 rings), the call is sent either to another member or to the front of the queue, if no calling group member is available.
  
  
• Auto Login. This setting is for calling groups used for fax machines or data (also called data hunt groups) to specify that the system automatically log in calling group members following a power failure. Auto Login can be set for calling groups where members answer telephones.
  
  
• Integrated VMI. This setting is used when a voice messaging system (such as AUDIX Voice Power or the MERLIN Messaging System) that requires special signaling for integrated operation is connected to one or more extension jacks assigned to a calling group. The system automatically logs in the calling group members after a power failure.
  
  
• Generic VMI - This setting is used when a voice messaging system (such as Avaya Attendant or Integrated Voice Power Automated Attendant) that does not require special signaling is connected to one or more extension jacks assigned to a Calling Group. The system automatically logs in the Calling Group members after a power failure.

You can program SMDR to provide more detailed information about calls to Auto Login or Auto Logout calling Station Message Detail Recording (SMDR).

An EXPRESSO System directly connected by a PRI tandem trunk or tie trunk to another EXPRESSO System (Hybrid/PBX mode only) can use the voice messaging system (VMS) of that EXPRESSO System (see Centralized Voice Messaging for more details). External alerts and Music-On-Hold sources, however, work only for the system where they reside. Each networked system should include its own voice mail and/or Auto Attendant applications as well as its own external alerts and Music-On-Hold sources. A single Auto Attendant, however, can transfer calls throughout the network. It can answer only those calls that arrive on the PSTN facilities of the system where it is connected. For this application, 4-digit pool and line/trunk numbers are recommended. To avoid ambiguity, trunks should be unique�for example, 890 and 8900 should not be used together. Calls received on PSTN facilities can be answered at a remote system in a private network by assigning the trunks to a calling group with a non-local member.
