Ringing Group Feature

The ringing group feature is based on call request to group. <br\>

Description

Compared to the Call Request feature the Ringing Group system has the following differences:

If the caller terminate the call/hangs up, the ringing group call is automatically removed from all station within the ringing group.
Private ringing tone is used for stations receiving a ringing group call.
The caller can be answered from any member of the ringing group by "M-key" or "OFF HOOK"
The private ringing tone can individually be muted by pressing "C-key" at a station in the ringing group
The first caller in a queue for a ringing group is displayed in idle ringing group members station displays. (Mail in idle)
When a new call to a Ringing Group is made, notification of new priority mail is avoided.
The private ringing timeout time is by default 30 minutes. The timeout is controlled by the "Call Requester Reminder Time" timer.
Any number of stations can be member of a ringing group

AlphaCom factory default directory numbers 6701 to 6710 are predefined as Ringing Groups related to station groups 51 to 60. <br\>

AlphaCom factory default is set to automatic UK style private ringing tone on a ringing group if the call originating from SIP/trunk. <br\>

AlphaNet Configuration

Ringing Group in AlphaNet is fully supported as from software version AMC 10.50. The Ringing group feature is by default global. The activation of a ringing group call is sent as broadcast to all nodes in AlphaNet. This implies that the same local (ringing) group number is activated in all nodes.

To manage failure situations the Ringing Group mail has a 30 seconds timeout. While the initiator of the ringing group is in call requester mode the mail timeout is globally updated every 10 seconds. This means that if the data communication to the initiator node fails the ringing group calls on remote nodes will be terminated withing 30 seconds. (For regular call request the timeout is 7.5 days)

No particular configuration is required for ringing group used in AlphaNet. <br\> If global behaviour is unwanted the feature can be turned off by the nvram setting:

ex_profile.glob_const.glob_ring_gr = 0  (default 1)

Special Adjustments

To disable different ringing tone from external calls currently the TST console nvram function must be used to set the following parameter:

Nvram: ex_profile.flags.trunk_call_req_ringing = 0

The tone-pitch used for UK private ringing can be selected by

Nvram: ex_profile.glob_const.alt_priv_ring_tone = 1

0 = 500HZ TONE
1 = 400HZ TONE
2 = PRIVATE RING TONE
3 = ATTENTION TONE (muted)
4 = ATTENTION TONE
5 = BUSY TONE (muted)
6 = BUSY TONE
7 = DIAL TONE
9-20 = DTMF TONES

Forward a ringing group to a telephone number or other ringing group after a selectable time out if no answer. <br\> 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. <br\>
