From a telephone, call a extension defined in the phonepatch.
On the telephone link and the user radio, a message like "Radio call for _station_" (defined on report_call_audio) will be heard. Station name is syntetized with Festival. You can create your own audio files to hear a more friendly voice.
Press answer_button on the microphone of the user radio.
Now it should be possible to talk in both directions
From the user radio press the button askfortone_button, a tone should be heard for tone_audio_time seconds.
When the tone audio finishes, dial the destination number and finally press call_button, the call should now start..
While asterisk is trying to stablish the call, a ring audio will be listened (ring_audio) on the radio.
If the call is not answered, the (ring_timeout_audio) will be listened and the communication will be closed.
If the call is answered, the phonepatch opens the bridge, and it should be possible to talk in both directions
