Message Waiting Indication - Residence V13.0

History Log

Product Description

Message Waiting Indication - Residence signals that a message is in a voice mailbox and is waiting to be retrieved. There are three different ways in which Message Waiting Indication - Residence can be identified:

  • Audible - An interrupted dial tone is heard when the receiver is picked up indicating there is a new message.
  • Visual - A visual signal is generated when there is a new message (requires a visual device, such as an illuminating lamp).
  • A combination of both Audible and Visual is available which generates both an interrupted dial tone signal and a visual signal when new voice message(s) are waiting.

End-users who want a visual signal must purchase compatible equipment.

When Message Waiting Indication is activated, the end-user may call to retrieve the message or ignore the signal and place a call. Message Waiting Indication continues until the switch receives a deactivating signal from the voice messaging system.

There are three types of Message Waiting Indication:

The sound of the Message Waiting Indication Residence - Audible differs depending on the switch type:

Switch Type Description
5ESS® and Ericsson 10 interrupted dial tone cycles, followed by a continuous dial tone.
DMS™-10 Two seconds of interrupted dial tone followed by a continuous dial tone.
DMS-100 Unchanged continuous interrupted dial tone (does not change to continuous dial tone until Message Waiting Indication - Residence feature is deactivated by retrieving messages).

A telephone set must be on-hook to receive signals for turning the message light on and off.

If the receiver is off-hook (talking, dialing, checking messages etc.) the central office will continuously try to deliver the signal. After 2 1/2 hours, the following happens:

Switch Type If phone is still off hook after 2 1/2 hours:
5ESS Switch will attempt to re-send the ON/OFF signal every 1/2 hour.
DMS-100 Switch will attempt to resend the ON signal only. The OFF signal will be lost.


Central office (CO) switches must be specially equipped to provide the various Message Waiting Indication features - Audible and/or Visual. On all new requests, contact your CenturyLink Service Manager to determine availability.
