Camp-On-Busy
When the party you are calling is on another line, by simply
waiting you automatically "Camp-On" the line. (Busy tone
sounds continuously.) As soon as the line is freed, you will
be automatically connected.
Busy Call Back
The disadvantage of the camp-on-busy function is that a
link is occupied and busy tone is heard from your station
all the way while you are waiting. This problem can be
avoided by using the busy call back function that can im-
prove the availability of speech paths as well as enables you
to wait without being annoyed by "noisy" busy tone.
A maximum of 15 stations can be registered for this func-
tion. Once the function has been programmed into your
station, you are put in the simple "busy waiting" mode
even when you depress 6 in an attempt to register other
busy stations for this function.
It is possible to make or receive other calls while waiting
after this fuction has been programmed. However, if you
are still using your station for conversation with the third
party when the busy station registered for this function
is freed, the registered busy call back function will be
cancelled.
Camp-on-busy is prior to busy call back.
When the called station is busy, dialing
permits this function to be registered and terminates the
call after a confirmation tone. As soon as the line is freed,
the calling party is called by the distinctive "busy-call-back"
tone that sounds for 10 seconds. By one-touch dialing any
one of
key during the 10-second
period, the calling party can be connected to the called
party.
