Callback calls are useful when a softphone cannot be registered due to an error or when poor network quality affects call quality.
When using a callback, Communicator GO tells the server to call the user's callback mobile number via a GSM network.
The VoIP protocol will connect the other party, if possible, or the GSM. For the callback feature to work, users must select a number in the callback settings of the application where they will receive GSM calls.
