Station Message Wait/Call Back
When a Called Station does not answer or is in DND, a Station User can activate a Message
Wait Indication (MWI) to request a Call Back. A Station may receive a MWI from any number
of other Stations in the System. The Station receiving the MWIs can return the calls using the
[MSG/CALLBK] button.
When a Busy Station is called, the Calling User may request to be placed in a queue to receive
a Call Back. When the Called Station returns to Idle, the System notifies the Initiating Station
with Call Back ring. When the User answers, the previously Busy Station is called.
When a Message is waiting, the [MSG/CALLBK] button LED will flash; when MWI is received
at a SLT, the MW lamp will flash.
CONDITIONS
- A Message Wait/Call Back Return Call will always ring at the Receiving Station
overriding the Intercom Signaling mode selected.
- A Station can leave only one Call Back request.
- The [MSG/CALLBK] button LED will continue to flash until all MWIs and Call Back
Requests, have been serviced (including Voicemails).
- If a Station is attempting to leave a message and the System MWI queue is full, the
oldest MWI will be deleted.
- A MWI Reminder Tone can be enabled to remind the user of MWIs.
- A Station in Call Forward can leave a MWI.
- A MWI is left at the Originally Called Station even if the call is Forwarded.
- A Digital Phone with LCD may Call Back to Stations that left messages in any desired
order, or the normal (“oldest first”) order.
- Placing an Intercom call to a Station will cancel any existing MWI from that Station.
- A Station can support up to 99 VMS messages.
- If a Station requests a Call Back at a Busy Station, a Call Back Request Station will
check the Busy Station’s status every 5 sec., and receives Call Back Ring when the
Status Check Timer is expired (after the Busy Station returns to Idle). For this reason,
Call Back ring may be delayed after a Busy Station returns to Idle, and when several
Stations request a Call Back at a Busy Station, the Call Back Ring may not be
provided sequentially. Operation
