Allowing PTT Broadcasts to Play During Active Calls
The Accept While Busy option allows PTT broadcasts to come in as active calls (if enabled) as Pending (if disabled). A Pending page displays as if it were held.
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, the incoming PTT broadcasts won't disrupt the phone call, and you won't hear the broadcast. To hear the PTT broadcast, select the broadcast and press the Select soft key (the phone call will automatically be held). Or, hold or end the phone call.
