8) 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 or key during the 10-second
period, the calling party can be connected to the called party.
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 improve the availability of
speech paths as well as enables you to wait without being
annoyed by "noisy" busy tone.
You can only register one (1) busy station for this function. 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 function has been programed. 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.
