Allowing PTT Broadcasts to Play During Active Calls
The Accept While Busy option allows PTT broadcasts to come in as active calls
(if enabled) or held calls (if disabled).
If enabled, a PTT broadcast will interrupt telephone calls and you'll hear the
audio of both the telephone call and the PTT broadcast. The party on the other
end of the telephone call cannot hear the PTT broadcast unless that party has
also enabled Accept While Busy.
If disabled, PTT broadcasts are held during an active call. To hear the
broadcast, you have to resume the broadcast.
