Calling Party Control detection
When a caller hangs up, the central telephone exchange will issue a
signal called a Calling Party Control (CPC) signal. The built-in
answering machine has been set to detect this signal, and this allows it
to immediately stop recording when a caller hangs up, thereby saving
memory space and freeing you from having to listen to long periods of
silence when you play back your messages.
However, if you are a subscriber to such telephone services as Call
Waiting or Call Forwarding, signals used by these services may be
mistaken for a CPC signal, causing the machine to hang up during a
call. In this case, follow the steps below to turn off CPC detection.
Note: CPC detection may not operate properly in some telephone
exchanges. For this reason, periods of silence and/or telephone company
signals may be recorded even if CPC detection is turned on.
