Features and Services
Operating parameters
A Group Call can be originated only from a Meridian 1 proprietary telephone
with a Group Call key.
Group Call does not support data calls.
With the Extended Conference TDS (XCT) card (NT8D17) audio
interference can occur if many of the call participants are on older-style
mechanical analog (500/2500-type) sets. This problem does not occur when
participants are on Meridian Digital Telephones or newer-style electronic
analog (500/2500-type) sets. Mechanical analog (500/2500-type) sets
produce more audio noise and degrade the sound quality of the conference as
the number of participants exceeds 12-15 members. As the number of
participants drops below this threshold, the sound quality of the Group Call
returns to normal.
The maximum number of members per group is 20.
For Option 11C, the maximum number of members per group is six.
The maximum number of groups per customer is 64.
Each group member DN must have a Warning Tone Allowed Class of
Service.
Off-premise Extension (OPX) lines cannot be members of a group.
Calls to a DN that is active in a Conference call, or Group Call, are blocked.
