Who is it for?

♦ ITSPs launching a prepaid calling card business, especially in newly deregulated markets
♦ Carriers looking for enhanced profit from the global long-distance network
♦ Service providers who already offer prepaid and post-paid calling card services over a switched circuit network
♦ Telecom companies and other service providers interested in offering calling card services to a wide range of important target communities (students, MLM, etc.)

How does it work?

The caller dials in, using either the local or 800 phone numbers for the service provider. Alternatively, the call can be placed using compatible PC phone client software (Windows Messenger, X-Ten). The VoIP gateway, assisted by the IVR server, prompts the caller to enter his/her account ID (PIN).  Once the previous step is completed, the system authenticates the caller, prompts the VoIP gateway to announce the account balance to him/her, and signals him/her to dial the destination number. After the destination number has been entered, the system calculates the maximum call duration and plays it back to the caller via the gateway’s IVR. Once the call is completed, it is charged to the caller’s account balance. The calling card user may log in to the account self-provisioning interface at any time to access call history (CDRs), payment information (credit card info), language options, and many other features.
