Volume Boost
The Volume Boost setting increases the volume of PTT calls and Integrated Secure
Messages (voice messages and video messages) while the device is in speakerphone mode.
Volume Boost does not affect application tones or PTT call volume in accessories, including headsets
or RSMs. The volume is not boosted when the speakerphone is turned off.
NOTE:
On iOS 13.1, when the PTT app is in the background and the Volume Boost is set to
anything other than the default, no audio is heard during an incoming PTT call.
Boosting the volume may decrease sound quality.
The Volume Boost setting is only available on supported devices.
