Ringing Group Feature

The ringing group feature is based on call request to group. The behavior of the ringing group call request is changed compared to regular call request: - If the call requester leave call requester mode or hangs up (SIP) the call request is automatically removed from all station in the ringing group.

Current setup need the following configuration:

Program a directory number for the ringing group A directory number must be entered in AlphaPro using the feature:

FEATURE_CALL_REQ_GROUP 109
param1 = group number

To select internal or external ringing tone A flag must be set to activate UK style private ringing tone on calls orginating from SIP To enable different ringing tone from external calls currently the TST console must be used to set the following parameter:

Forward a ringing group to a telephone number or other ringing group after a selectable time out,if no answer. This is done by forwarding of call request by using search strings. The search strings for ONE of the stations in the ringing group can be used for programming of behavior after a configurable timeout in private ringing mode.

We can pick up a call by lift handset, or by "M" button, and we can stop ringing tone on actual telephone by press "C" - Suggest to add functionality to the station flag : Mail In Idle. (Alternatively add a new flag). M-key or Handset from Idle will then answer the first call request in the queue. - C-pres will mute the ringing tone for a configurable number of seconds, but not remove the call request?

We can activate a RCO by a ringing group - Use the event handler. Mail in idle.
