call without any user intervention.
Voice Communication
After a private call is established, either the calling party or the called party can make a
voice call only if the PTT key is free. The PTT key is free when the radios of both parties
display the PTT Admit screen. The PTT Admit screen is displayed immediately after a
call is established and when neither party is speaking. With no activity it will remain
displayed until the preset inactivity time expires.
