Call Coverage

If the number-of-rings interval for coverage is shorter than the automatic transition interval, the system redirects the call to coverage before the system audibly alerts a call appearance that has delayed ringing. However, the system continues to increment the timer for the automatic transition interval, in case no coverage point is available, and the call continues to alert at the telephone.

When a call is immediately redirected to coverage, the Ringing - Abbreviated and Delayed ringing has no effect on the system processes.

Call Forwarding - Busy/Don’t Answer

When the system forwards a call because no one answers the call in the specified interval, the call stops alerting at the telephone. The Ringing - Abbreviated and Delayed feature does not affect the manner in which the system processes the call. However, the system continues to increment the timer for the automatic transition interval, in case forwarding fails, and the call continues to alert at the telephone.

If the interval for call forward don’t answer is shorter than the interval for automatic transition, the system redirects the call to the forwarded-to extension before the call rings at a telephone that has a ring type of delayed ringing.

Call Vectoring - Expert Agent Selection - Logical Agents

Calls that the system routes to a logical agent use the translations for the Ringing - Abbreviated and Delayed feature of the telephone that the agent uses.

Data Extension Calls

Data Extension calls are unaffected by the ring values. The calls continue to be directed according to the way that you administered bridged call alerting.

Hospitality Features - Do Not Disturb

The Do Not Disturb feature takes precedence over the Ringing - Abbreviated and Delayed feature in blocking ringing to the telephone.

Integrated Services Digital Network (ISDN) - World Class Basic Rate Interface (BRI)

Several of the protocol variations that the World Class BRI feature restrict the messaging that is required for control of a telephone ringer by the Ringing - Abbreviated and Delayed feature. If the protocol variations do not permit the required messaging for the telephone ringer, the system rings the call at the telephone, and does not transition the ring.

Multiappearance Preselection and Preference

If the Per Button Ring Control field on the Station screen is set to n, the system automatically selects any call that alerts at a telephone. The call can alert in a manner other than ringing.

If the Per Button Ring Control field on the Station screen is set to y, the system automatically selects any call that rings at a telephone.

Off-Premises Station (OPS) and Off-Premises Extension (OPX) lines

You must use a ring type of ring for OPS and OPX lines.

Personal Central Office Line (PCOL) calls

Ring values do not affect the processing of PCOL calls. PCOL calls continue to be directed according to the way that you administer bridged call alerting.

Redirection Notification

If you enable Redirection Notification, telephones receive redirection notification only if the alerting button, or the first call appearance, has an assigned ring value of ring or abrv-ring.

Terminating Extension Group (TEG) calls

Ring values do not affect the processing of TEG calls. TEG calls continue to be directed according to the way that you administer bridged call alerting.

Voice mail systems

Voice mail systems might look for ringing that is applied to a port to trigger call answer. Ring-type translations that are inappropriately set for ports that serve a voice mail system, can result in undesirable operation of the adjunct.
