PROTEI IVR is a carrier-class automatic voice service system geared towards various customer care, information and entertainment services. PROTEI IVR can interact with TDM equipment via SS7, EDSS-1 as well as with NGN platforms via SIP. Modular SIP-enabled architecture allows easy system integration into perspective IMS environment.

This system enables interactive self-service capability and outbound subscriber notifications.

The system covers standard IVR functions and operations like including balance inquiry, payment registration, services activation/deactivation, tariff change, low balance notification etc and wide range of information services also. By using DTMF, subscriber can navigate to a particular menu item, e.g., number activation/deactivation or balance enquiry. If it is necessary IVR can interact at any point of dialogue menu with external information systems (e.g. mobile Operator’s billing system) to retrieve the requested information or to change necessary settings in the subscriber’s profile.

All menu schemes can be easily defined by the System Administrator by using voice menu constructor (service creation environment). Outbound notification (mass calling) can be initiated by the request from the billing system or by the System Administrator.

Integration with 3rd party ASR and TTS engines allows to manage voice services flexibly.
