Callback allows the user to use the cellular voice network for calls instead of the cellular data network (VoIP) calls. This may be useful if you have low-speed connectivity, cellular data coverage is poor, or mobile data costs are too high. When you make a call with cellular callback, the VoiceONE cloud calls your mobile number, waits until you answer the call, and then connects you with the number you are calling.
The callback feature is available on both Android and iOS application.
You can configure the Mobile Calling Method of the Call Settings in one of the following ways:
- Use Internet will use internet data connection for all outgoing calls.
- Use Callback will use callback for all outgoing calls.
- Ask Each Time Connect will show a dialog asking to choose between Internet and Callback on each outgoing call.
