Message Waiting Indication - Business V14.0
Product Description
Message Waiting Indication -Business works in conjunction with Message Delivery Service and Message Delivery Service - Interoffice. It provides an audible or visual or audible/visual indication of messages waiting.
End-user lines may be equipped with only one of the Message Waiting Indication features. So if the end-user wants to receive both an audible and a visual message waiting indication signal, the Message Waiting Indication - Audible/Visual feature must be used to provide the service.
Message Waiting Indication - Audible (MWI-A): Provides an interrupted dial tone that is heard when the telephone receiver is lifted indicating a message or messages are waiting to be retrieved from a voice-messaging provider.
Message Waiting Indication - Visual (MWI-V): Provides a visual signal to the end-user that one or more messages are waiting to be retrieved. The end-users line must be in an "on hook" condition to receive the visual alerting signal.
Visual Message Waiting Indication requires an end-user provided visual device, such as an illuminating lamp or telephone with a visual indicator.
Message Waiting Indication - Audible/Visual (MWI-AV): Provides the end-user line with both an audible interrupted dial tone and a visual signal that one or more messages is waiting to be retrieved. The Message Waiting Indication signals are returned on the end-user's telephone line, which must be in an "on-hook" condition to receive the visual alerting signal or to deactivate the visual alerting signal.
Turning Message Waiting Indication on or off with CenturyLink Voice Messaging Service:
If Message Waiting Indication is working with CenturyLink Business Voice Messaging the end-user can turn the Message Waiting Indication indicator on or off at will by accessing their Business Voice Messaging Service mailbox, choosing Option 4 and following the voice prompts.
Turning Mwessage Waiting Indication on or off with all other voice messaging providers:
All requests to turn Message Waiting Indication features on or off are initiated by the voice messaging provider's Customer Provided Equipment (CPE) when it sends messages to the central office switch asking it to activate or deactivate the end-user's specific message waiting indication signal.
The audible signal is then initiated or turned off by the switch. For visual signals, the central office switch sends a coded burst of data in American Standard Code for Information Interchange (ASCII) format over the end-user's telephone line using FSK (Frequency Shift Key) signaling which tells the CPE device to light or to turn off.
The voice messaging provider determines how often signals will be sent to the switch to activate or deactivate the Message Waiting Indication signals sent to the end-user. Generally the provider's equipment will:
- Initiate a request for activation of Message Waiting Indication upon receipt of the first incoming message for the end-user. The activation request is not repeated.
- Initiate a request for deactivation of Message Waiting Indication after the end-user has accessed their voice mailbox. The provider may choose to deactivate the signal whether or not the end-user has retrieved any messages.
When a Message Waiting Indication feature is activated, it does not affect operation of the telephone line. The end-user may:
- Call their provider to retrieve messages
- Ignore the signal and place outgoing calls
- Receive other incoming calls
The interrupted dial tone and/or visual signal will continue until the switch receives a request to deactivate the signal from the voice messaging provider's CPE.
Availability
Central office 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.
