AUDIX Interface

LWC Cancel cannot be used to cancel an AUDIX message.

Bridged Call Appearance

A LWC message that is left by a user on a bridged call appearance leaves a message for the called party to call the primary extension for the bridged call appearance. When a user calls a primary extension and activates LWC, the message is left for the primary extension, even if the call was answered at a bridged call appearance.

Call Coverage

You can use LWC with or without Call Coverage. However, the two features complement each other. LWC provides the Coverage Callback option. Also, a caller can activate LWC for the called party even if the call was answered by a covering user.

Centralized Attendant Service (CAS)

LWC Message Retrieval does not work with CAS.

Conference

A member of a conference call cannot activate LWC because the user cannot be uniquely identified. After LWC is activated for a party on a conference or transfer, the origination of the conference or the transfer cannot press Conference/Transfer a second time to return to the original call. The originator must select the call appearance button to return to the previously held call.

Distributed Communications System (DCS)

LWC works with DCS, but only for 4- digit and 5-digit extension dial plans. LWC works with QSIG for all dial plans of 3- through 7-digits.

Expert Agent Selection (EAS)

When an EAS agent is logged into a telephone, the agent can only retrieve LWC messages that are left for the login ID of the agent. To retrieve LWC messages that are left for that telephone, the agent must log out.

When an EAS agent is logged into a telephone, the Message lamp of the telephone defaults to tracking the status of LWC messages waiting for the telephone. However, you can assign the Message lamp to track the status of LWC messages waiting for the login ID of the agent.

Message Waiting Indicator (MWI)

As QSIG does not specify a standard way to light the MWI lamp upon receipt of an LWC message, systems running Communication Manager must work properly.

Vector Directory Number (VDN)

LWC messages cannot be stored, cancelled, or retrieved through VDN extensions.
