General Description

This feature enables a PS user to call a maximum of “20-Party (self + other 19 members)” conference, only by dialing a pre-programmed Group Calling Conference Number. If the Group Calling Conference Number is once dialed, the member PSs/Stations are automatically called in assigned order at the interval of every two seconds. This feature also allows the Station Hunting Group - Circular, and the use of Phantom Telephone Number(s) which is available for flexible arrangement of conference member tables.

2.The conference leader hears Ringback Tone.

3.When the first party (conferee) answers, Ringback Tone stops, and the conference is in progress.
