PSTN Call Generator - VoIP Testing
The QPro is a multi-technology call quality analyzer enabling users to perform circuit switched and voice over IP testing of many quality parameters over any type of interface. The QPro’s greatest advantage as a VoIP call generator is its VoIP testing flexibility in configuration, test progress, and test types.
