Feature Reference
Considerations and Constraints
A telephone without a speakerphone, loudspeaker, or speakerphone adjunct
cannot be a member of a speakerphone paging group.
After using Loudspeaker Paging, users must be sure to disconnect the paging
call. Otherwise, the loudspeaker paging system may not be available by
someone else.
When a user tries to direct an announcement to a speakerphone paging group
that is receiving a page, the user hears a busy signal.
When a group member does not hear the announcement, the caller is not
notified unless all telephones in the group cannot hear the page, in which case
the caller hears a busy signal.
If an analog multiline telephone user does not have Voice Announce to Busy
and lifts the handset while listening to a speakerphone page, he or she is
disconnected from the page.
If an analog multiline telephone user with Voice Announce to Busy or an MLX
telephone user lifts the handset while listening to a page, the page continues
and the user can still make a call.
A maximum of three line jacks can be programmed for Loudspeaker Paging
and used to connect a single-zone or multizone paging system. Each zone
requires its own loudspeaker paging jack, and users cannot use more than one
paging system at a time by dialing a single access code.
Using the speakerphone for making a Speakerphone or Loudspeaker Paging
call may create a feedback tone.
Loudspeaker paging jacks are LS or GS line ports programmed as paging
ports. Up to three can be programmed. An extension jack cannot be
programmed for loudspeaker paging.
Any loop-start or ground start/loop start line/trunk jack can be assigned as a
loudspeaker paging jack. A line/trunk jack on an 800 DID, 100D, or 400EM
(tie trunk) module cannot be programmed as a loudspeaker paging jack.
The loudspeaker paging jack cannot be assigned to a pool that contains trunks
used to make or receive outgoing calls.
When a line/trunk jack is assigned for Loudspeaker Paging, only the
loudspeaker paging system can be connected.
If the loudspeaker paging system is multizone, users must dial the appropriate
zone number specified by the paging system before making an announcement.
