Keywords:
For Avaya Aura® deployment, the Ring Again feature is called the Automatic Call Back feature. The call-back operation is often referred to as Ringout or Ringout call.
For UNIStim endpoints, the Ring Again feature key is mapped to the Auto Callback key at a fixed position key. This fixed position key maps to a context-sensitive soft key and is active only when the capability is needed and applicable. Device Adapter treats it as a legacy RGA button and provides localization for UNIStim and all 39xx endpoints, except the 3901 endpoints.
For digital M3903, M3904, and M3905 endpoints, the Ring Again feature key is mapped to the Auto Callback key at a fixed position in the soft keys, in the same way it is done for the UNIStim endpoints. Other digital sets must have the Auto Callback key assigned to one of the available programmable keys. Device Adapter treats the Auto Callback button as a legacy RGA button, and provides localization for the M3902 set that has programmable soft keys, and for the M3903, M3904, and M3905 sets.
Analog sets can invoke Ring Again by using the Communication Manager Automatic Call Back Feature Access Code. Device Adapter treats it as a Flexible Feature Code equivalent.
Note:
CS 1000 and Device Adapter does not support Ring Again feature on the PSTN trunks. Ring Again feature is supported only for local and private trunks.

Ring Again, Busy Destination

This feature works in the following manner:
  • A user makes a call, which terminates on a busy destination. The phone displays the Ring Again key or soft key.
    Note:
    The phone does not display the Ring Again key if the call was made using a PSTN trunk.
  • The user decides to activate Ring Again and be informed of the called party becoming idle and presses the Ring Again key.
  • The user’s phone screen returns to an idle state with the Ring Again key indicating it is active.
  • The user can cancel the Ring Again request by pressing the Ring Again key before a callback offer is received. A callback offer is received when Avaya Aura® presents the Ringout call invitation.
  • Eventually, the called-party station goes idle and is now available for a return call. When the endpoint receives a callback offer, the Ring Again key flashes and an audible tone is heard to indicate that a callback offer is received.
  • The user answers this Ringout call like a normal call by off-hook or by selecting the ringing call appearance.
  • The Ring Again feature can be activated for calls made from any line DN key.

Ring Again on No Answer

A corresponding variant is available for Ring Again on No Answer (RANA). For RANA, the same button is used, but the behavior is different.
Upon encountering a station that does not answer, a station with the Ring Again capability can activate RANA by pressing the Ring Again key. Later, when the desired station goes off-hook to make or receive a call, and then goes on-hook, the station that activated Ring Again receives a buzz through the telephone's loudspeaker while the lamp flashes if that station is idle. The station user can dial the desired station by lifting the handset or pressing a DN key, and then pressing the Ring Again key.
This feature works as follows:
  • User A calls user B. User A receives a ring-back tone.
  • The user waits long enough to decide to activate RANA.
  • User A presses the Ring Again (RGA) key. The RGA key indicator turns on steadily.
  • User A either goes on-hook or presses the Release (RLS) key. The indicator associated with RGA key remains on and user A is now free to receive or make other calls.
  • User B goes off-hook to make a call, and then goes on-hook. User A is given a short ring through the loudspeaker and the indicator associated with the RGA key flashes.
  • User A either picks up the handset or presses a DN key. User A receives dial tone.
  • User A presses the RGA key. The user against which the Ring Again was placed is rung and the indicator associated with the RGA key is turned off.

Caveats

The user who requested the Ring Again service must accept the offer in a timely manner. That is, in a duration of six ring cycles. If the user does not answer the call-back request from the Ring Again service, the request is cancelled. This has implications when the Ring Again requesting party is on a fully busy station. If no appearances are available at the time of the Ring Again call-back offer, the request is cancelled.
The called party may go back off-hook before the user requesting Ring Again completes the retry of the original call. This is uncommon but may occur when the Ring Again target ends one call and starts a second immediately. If the user that requested the Ring Again accepts the Ring Again call-back request, the user may encounter a Ring Again, Busy case.
Analog endpoints encountering a busy destination are offered a choice of options rather than a button. They can enter a service code as provided by the server and activate Ring Again.
If the user attempts Ring Again to another target station, the initial Ring Again is cancelled. Users can only have one active Ring Again.
