When the caller ends the call, the device automatically hangs up. However, it is possible to answer and hang up using the corresponding key. The device responds to commands with low and high tones and, for greater versatility, has relay outputs with normally closed (NC) and normally open (NO) contacts.
The device's operation will be affected if the answering machine is active. Furthermore, Cebek does not guarantee compatibility with fiber optic lines or mobile voice boxes due to the different line voltages used by these devices.
