AT&T 2.1.1 manual Call Coverage Paths, Calling Groups

Feature and Planning

Call Coverage Paths

The Fax Call Answer service can be used to provide coverage for calls that are not answered by the fax machine at the called extension, and for personal fax numbers that do not have fax machines. In order to provide this coverage, the switch must direct the call to the Fax Call Answer service when the switch detects that the telephone is busy or the maximum number of rings has occurred. The designation of one or more places to direct a call is known as the call coverage path.

The Fax Call Answer service of FAX Attendant acts as a call coverage point.

If the fax machine’s extension is busy or does not answer, the call will be sent to the Fax Call Answer service.

In other cases, particularly when there is a personal fax extension but no actual fax machine, calls are sent to the Fax Call Answer service.

It is necessary to plan the call coverage path for each subscriber. The FAX Attendant System Manager must work closely with the Switch Administrator to coordinate this effort.

Calling Groups

A single calling group assigns a single number that rings at any available extension within the group.

The 12 voice channels that are available for AUDIX Voice Power and FAX Attendant services must be arranged into groups for each service that will be used. Fortunately, several of the most used services can share the same group. The MERLIN LEGEND Communications System supplies information about the call that allows AUDIX Voice Power/FAX Attendant to determine which service to provide for the call. Separate calling groups and channels must be assigned for the following services:

Message Drop Service (usually only one channel).

Information Service (usually only one channel or replaced by Automated Attendant).

Fax Response Service.

A single calling group (the Automated Attendant group) should be used for Voice Call Answer, Fax Call Answer, Voice Mail, Fax Mail, and Automated Attendant. The service provided is based on whether the call is internal, external, or coverage, and whether the called extension is a voice or fax extension. If you do not want to use the Automated Attendant Service, use the single calling group for for Voice Mail Service to receive Voice Call Answer, Fax Call Answer, Voice Mail, and Fax Mail.
