Ringing Group Feature

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

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)
*A member of an ringing group can not activate a call to its own ringing group.

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

31 &000172 .ex_profile.flags.trunk_call_req_ringing = 0

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\>

Call Request forward by search strings <br\>

If forwarded to another station or group the call request will be removed from the original ringing group. If just additional station should be added a new ringing group with the original members and new members should be used. <br\> Example of including additional station after timeout in first ringing group:

Ringing group 1 (directory number 6701)= station 1, 2 and 3
Ringing group 2 (directory number 6702)= station 1, 2 ,3 ,4 ,5 and 6.
Search string on station 1 : I6702
