Abstract: A method of establishing a registration between a mobile device and a server includes receiving at the server an SMS or MMS from a mobile device. The server receives the phone number of the mobile device, verifies the phone number of the mobile device against a whitelist to authorize a registration between the mobile device and the server, and verifies a secure identification code that is input at the mobile device. The secure identification code is provided to a user of the mobile phone before the mobile device is registered with the server. The secure identification code can be provided to the user via an administrator of the server. An encryption key established between the mobile device and the server can be used to provide or enhance encryption of a voice communication, such as a VoIP communication, made using the mobile device.
