VOICE OVER INTERNET PROTOCOL PAYPHONE DIAL TONE SERVICE SYSTEM

摘要

The Payphone Dial Tone Service System receives control and communication data via a VoIP communication connection that originates at an Analog Terminal Adapter and modem connected to the smart payphone. The Analog Terminal Adapter and modem communicate exclusively with the Payphone Dial Tone Service System of the Payphone Dial Tone Service Provider and transmit a unique code to identify the smart payphone. The Payphone Dial Tone Service System validates the smart payphone and originates an Internet-based communication session to the appropriate carrier or Public Switched Telephone Network gateway. The Payphone Dial Tone Service System also manages the ANI data to ensure proper terminal identification and AMA billing.
