PTT Configuration
You can configure PTT to a different default channel, you can allow PTT broadcasts to override an active
call, and you can subscribe or unsubscribe to channels that the system administrator has enabled.
Accept While Busy
The Accept While Busy option allows PTT calls to come in as active cells (if enabled) or as cells on hold (if
disabled).
If enabled, a PTT broadcast will interrupt telephone calls and you will be able to hear the audio of both
the telephone call and the PTT broadcast on the same audio selection. 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 placed on hold during an active call and in order to hear the broadcast,
you must select the PTT cell and press the Resume soft key.
To refuse or accept all PTT broadcasts while on a telephone call:
1 Navigate to Settings > Basic Settings > Preferences > Paging/PTT Configuration.
2 Select Accept While Busy.
3 Enable or disable as desired.
