Auto Provisioning feature allows the Mobile VoIP application to turn the mobile number of the end user into their user ID. This technology eases the sign up process as the mobile number becomes the PIN of the user.

The mobile number authentication is carried out by sending a password through an SMS or an IVR call. Post authentication, the user can automatically create a 'buddy list' out of the phonebook by adding those contacts, who are already using the mobile VoIP application.
