Multiple Calling Methods Supported

The Havex Cloud Voice App supports multiple calling methods. Even when users have no Internet connectivity they can still make calls by making use of GSM call-through, which is billed at the same low app calling rates. 

What Is Call-Through?

The App will call a toll free access number using your phone’s sim card, don’t worry this wont cost you anything. Upon answer the App will send through the number that was selected to call. The call will then hangup and the user will immediately receive a call back. Upon answering the callback the user will hear ringing as the access server tries to connect the call. This process takes a little longer to establish the call, but users will still benefit from the App’s super low calling rates.


Making Use Of Secondary Calling Methods

To access the secondary calling methods long press the dial button or number. A popup menu will be displayed as shown on the right. The user can then select one of the secondary calling methods.
