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)

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

AlphaNet Configuration

The groups configured used for the RingingGroup feature are local. To activate a ringing group from a remote node the ringing group should be activated bye a $SEND_MAIL message with the ringing group parameters set. Canceling of a ringing group also needs an event string. <br\> Example 1:<br\> A 2 node system.<br\> Node 1<br\>

• In node 1 there is no ringing group, the stations only activate the ringing group 1 in node 2.

Node 2<br\>

• Ringing group 1 configured with number "6701" related to station group 51. <br\>

Activate ringing group 1 in node 2 from node 1, dialing 6701: <br\>

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\>
