Group Calling Message-Waiting Indicator
Use this procedure to designate the extension that will receive message-waiting
indications (MWIS) for the calling group.
Only one extension can be designated as a message-waiting receiver for each
calling group; however, more than one calling group can use the same
message-waiting receiver. The extension assigned as a message-waiting
receiver does not have to be a member of the calling group.
Message-waiting indications cannot be sent to the extension assigned to the
group unless this option is programmed. The message-waiting receiver cannot
distinguish between messages left for the calling group and personal
messages.
