We place a specially developed iPhone app at our customer's disposal, which can be downloaded in the App Store.
Since the fonworld app allows you to make calls using a SIP access, your fonworld account has to be activated for SIP calls. The registration process must be accomplished completely and successfully. Our customer service will give notice by email as soon as your user account is established and all fonworld-functions are provided. Besides you are given information about the state of your account on your dashboard.
You can select which call number you want to transmit via SIP calls at any time at 'SIP Access' You can, however, only select call numbers which have been previously verified. To do this, please verify your telephone numbers in the customer centre at 'User Information'.
