Off-Hook Call Announce (OCA)

System Availability: All systems

Station users may announce a call when the station they call is busy talking with the handset off- hook. The announcement is only audible to the telephone user receiving the OCA call, not to the other party in the original conversation.

Two different methods of operation are provided – handset or speaker OCA. With handset OCA, the OCA caller’s announcement comes in on the telephone handset. With speaker OCA, the

announcement comes in on the speaker. Handset or speaker OCA can be set individually for each telephone that must receive OCA calls. Speaker OCA on digital DPs require a BVSU option for

DKT3200-series telephones or a DOCA-1A option for DP5000 telephones. Handset OCA has no optional hardware requirement. Speaker OCA on IP telephones (IPT2020-SD, IPT2008-SDL, and IP5000 terminal) requires an MIPU / LIPU / LIPS / GIPU / GIPH installed in the Strata CIX.

Note Each station enabled with Speaker OCA requires two IP channels on the same IP interface card but only one IP endpoint license.

When a busy telephone receives a handset OCA call, replying confidentially to the OCA caller can be accomplished by pressing the Msg button (toggle) to place the original call on hold or holding down the Mic button to make a short reply. In either case, the original caller will not hear the reply to the OCA caller. To reply to a speaker OCA call, the user covers the handset mouth piece and

talks back through the telephone microphone.

Any type of telephone can be enabled to originate OCA when calling a busy digital telephone. The feature is activated automatically (optional setting) or manually (Call Completion code – digit 5). Stations receiving OCA must be proprietary digital telephones assigned with OCA-receiving capability in system programming. Standard single-line telephones cannot receive OCA.

Any type of station can make an OCA call, as long as the station has this option enabled in system programming. OCA to DND telephones is allowed only if DND Override is allowed on the called and calling telephones.

Note The CIX40 supports Headset OCA on digital and IP telephones, but only supports Speaker OCA on IP telephones.
