CALL WAITING/CAMP-ON
Busy stations are notified that a call is waiting (camped-on) when they receive a tone. The tone is repeated at
a programmable interval. Digital keysets receive an off-hook ring signal through the speaker while single line
stations and IP keysets receive a tone in the earpiece of the handset. The volume of the camp-on tone can be
set by the station user. Camped-on calls follow Forward No Answer if a Forward No Answer destination has
been set.
Optionally any station can be programmed to automatically camp-on to a busy station instead of having to
press the camp-on button or dial a camp-on code.
CALLER EMERGENCY SERVICE ID (CESID)
This service is provided in the OfficeServ 7200 via an ISDN PRI circuit configured for both way DID connect-
ed to the TEPRI card.
This is a service where the telephone system sends a number, usually a call back number, to the Public Service
Answering point (PSAP) when a station user dials 911. This number is associated in the PSAP with a location
indicating exactly where the call originated. This allows the emergency services to respond directly to the
correct building or floor of a building rather than to have to make inquiries as to the location of the emer-
gency. This service is sometimes referred to as Enhanced 911 or E-911.
CENTREX/PBX USE
CENTREX and PBX lines can be installed in lieu of central office trunks. CENTREX and PBX feature access codes
including the command for hook-flash (FLASH) can be stored under one touch buttons. Toll restriction pro-
gramming can ignore PBX or CENTREX access codes so that toll calls can be controlled when using these
services.
CHAIN DIALING
Keyset users may manually dial additional digits following a speed dial call or chain together as many speed
dial numbers as are required.
CHAIN FORWARD
The chain forward option determines whether a forwarded intercom call that subsequently forwards to
voicemail will target the original stations mailbox or the second stations mailbox.
CLASS OF SERVICE
The system allows a maximum of 30 station classes of service. Each class of service can be customized in
memory to allow or deny access to features and to define a station’s dialing class. Each station can be
assigned different classes of service for day and night operation.
COMMON BELL CONTROL
The MIS daughter board provides relays that may be programmed to control a customer-provided common
bell or common audible device. These contacts must be programmed as members of a station group and
may provide steady or interrupted closure.
COMPUTER TELEPHONY INTEGRATION (CTI)
Computer Telephone Integration (CTI) allows integration between the OfficeServ 7200 and a personal com-
puter (PC) on a local area network (LAN). Caller ID service is required for TAPI inbound call applications that
