‘Ringing group’, which will be named as RG in this document, is very useful for IP-PBX’s users. It has following key features:

(1) When one incoming call to an extension that belongs to a ringing group, the others belongs to the same ringing group will ringing at the same time.

(2) When one picks up the incoming call, the others will be released.

(3) Only when all ones reject the call, MSS will reject the incoming call.

(4) If the caller is in the same RG, only the target called user will ringing.

Following figure describes the basic elements in this service.

Holly, Gilson and Hongtian are in the same RG. When caller make an incoming call to Gilson, Holly and Hongtian will ringing at the same time. If Hongtian pickup the call, the others who are Gilson and Hongtian will be released. Then, caller will talk to Holly.

In another hand, if Holly calls Gilson, Hongtian will not ring since they are all in the same RG.
