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.
