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 re-
corded even if CPC detection is turned on.
