It is also possible to display the Caller ID information on the LCD screen of the key telephones.
The IVT-16 series of key telephones can display both the name and number.
In some of
fi
ce situations, it may not be desirable to allow all key telephones to display and keep a
record of the Caller ID information describing the name and number of incoming callers. A new
parameter has been added to instruct the IVT-16D key telephone as to whether it will display the
Caller ID information as it is sent from the Central Of
fi
ce and keep a Caller ID history in memory.
(See “Programming The Extensions”, page 32)
IVT-16 key telephones which are not given this privilege will still be able to display the Caller
ID information for any call which is transferred to the key telephone while the call is in progress.
After the key telephone is no longer connected to the outside line, the Caller ID information is lost
from that phone. Be aware that this parameter setting is sent to the key telephone only when the key
telephone is
fi
rst plugged into the IPS system. Thus, the key telephone should be unplugged from
the system and then reconnected for a “Display Caller ID” programming change to take effect.
