Internal Antenna
The CTPhone handset features an internal antenna which is not subject to
physical damage because it is not extracted or retracted during phone use.

The CTPhone handset encrypts voice information before transmitting it.
Encryption ensures that conversations are private and inaccessible to
electronic eavesdropping.

Key Press Feedback
The CTPhone handset can be configured to beep when any key is

and relocks it again when the call terminates.
