Features and Services
Controlled Class of Service, Enhanced
If Controlled Class of Service (CCOS) is activated at a telephone on a
conference call, established Public Exchange/Central Office or toll calls are
not affected. The CCOS restriction level is applied immediately; however, no
new calls can be initiated from the conference. That telephone remains in the
CCOS state after the end of the conference.
Dial Access to Group Calls
The Conference feature cannot be applied to a Group Call.
Dial Intercom
If an analog (500/2500 type) telephone is part of a Dial Intercom Group
(DIG), the user of the telephone can conference only with another user whose
telephone is within the same Dial Intercom Group (DIG).
Digital Private Signaling System #1 (DPNSS1) Executive
Intrusion
Executive Intrusion is denied if the requested party is established in a local
conference, or if the requested party is involved in an enquiry call. These
restrictions may apply to the unrequested party depending on the connection
being used between the requested and unrequested parties.
End-to-End Signaling
The Attendant Console and the telephone receiving Attendant End-to-End
Signaling cannot both activate End-to-End Signaling simultaneously.
Group Call
Neither Call Transfer nor Conference can be initiated during a Group Call. If
an analog (500/2500 type) telephone user flashes the switchhook during an
established Group Call, the user is dropped from the call.
Held Call Clearing
Active Conference calls are cleared by an on-hook or Release key action.
Conference calls being held are cleared by an on-hook action only, and not by
a Release key action. In either case, all other parties on the conference remain
connected.
