*If the caller terminate the call/hangs up, the call request is automatically removed from all station within the ringing group.
*Private ringing tone is used for stations receiving the call request.
*The caller can be answered from any member of the ringing group by "M-key" or "OFF HOOK"
*The privat ringing tone can individualy be muted by pressing "C-key" at a station in the ringing group
*The caller is shown in idle state at all stations in the ringing group

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 300)= station 1, 2 and 3
Ringing group 2 (directory number 400)= station 1, 2 ,3 ,4 ,5 and 6.
Search string on station 1 : I400
