When a call is answered using Work for Mobile on an iOS device.
- Work for Mobile
- Open device Settings.
- Go to Privacy.
- Go to Microphone.
- Turn on the microphone for Work for Mobile (swipe to turn the switch green).
The likely cause of this issue is that microphone access for the Work for Mobile app is disabled. This can occur as a result of app updates, iOS system updates, phone reset, or simple user error.
