Here's how you make a one-to-one call in Tetrapol:
- To make a call, dial the calling ID on the terminal keyboard. You can also select the calling ID from the Tetrapol radio terminal's directory or redial from a list of previous calls.
- To take a call, just press the green key. You can also reject calls by pressing the red key or by simply not answering.
- To talk, press the push-to-talk key. Unlike with a mobile phone call, you can't speak at the same time as the other party. Like with other Tetrapol radio communications, you'll use a push-to-talk procedure for individual calls.
- To end the call, press the red key to hang up.
You can also make one-to-one calls on Tetrapol over a telephone network via PBX. And you can even have your call ciphered for added security.
