Message Waiting
n Description
An extension user can leave a Message Waiting indication at a busy or unanswered extension
requesting a return call. The indication is a flashing MW lamp at the called extension and a steadily lit
MW lamp on the calling extension. Answering the Message Waiting automatically calls the extension
which left the indication. Message Waiting ensures that a user will not have to recall an unanswered
extension. It also ensures that a user will not miss calls when their extension is busy or unattended.
Additionally, Message Waiting lets extension users:
·
View and selectively answer messages left at their extension (display system phone only)
·
Cancel all messages left at their extension
·
Cancel messages they left at other extensions
An extension user can leave Messages Waiting at any number of extensions. Also, any number of
extensions can leave a Message Waiting at the same extension. A periodic VRS announcement may
remind users that they have Messages Waiting.
Message Waiting Available for Single Line Telephones
This feature provides message waiting indications to single line telephones without message waiting
lamps. The system provides special dial tone as an additional method of indicating a message waiting
on a single line telephone with or without a message waiting lamp.
Note the following items for this feature:
·
This feature can apply to any analogue single line telephone.
·
Since it's possible that a user will pick up the handset and dial without listening for dial tone, the
system is able to detect dialling during special dial tone.
·
All of the message waiting indication methods may be active at any SLT.
·
Options are available based on a station's class of service.
·
These signalling methods are available to all analogue single line telephones, whether connected
to a 308M/308ME card.
·
The Message Wait dial tone will be a system tone and can be changed in Program 80-01 Service
tone number 3.
Conditions
Message waiting lamps at the SLT must be compatible with the XN120 operation (24V to 100V
switching at 500mS interval).
