Active Call Center comes in two flavors: a Standard Edition for development use and small telephony systems, and a Professional Edition specifically designed to operate with high availability even under heavy loads.  Click here for purchase information .

Number of Lines Supported 

The Professional Edition reliably supports up to 96 lines of simultaneous inbound calling under heavy loads.

Text-to-Speech Engine 

The Professional Edition includes the free Microsoft Text-to-Speech engine.  This engine is not reliable under heavy loads, so we offer as an add-on the Lucent Text-to-Speech Engine.  The Lucent Text-to-Speech engine provides reliable, scalable, text-to-speech generation in American English, Canadian and European French, Mexican and Castilian Spanish, German, Italian, and Mandarin.  We also have the possibility to provide the RealSpeak(TM) Text-to-Speech engine, please inquire for more details.  

Outbound Dialing 

The Professional Edition includes our single line outbound dialing object , which can be integrated with other applications to provide robust outbound calling capability.  For reliable, scalable multi-line dialing applications, a powerful Power Dialer object is available as an add-on.

Runs as a Service 

To provide added fault tolerance, the Professional Edition of Active Call Center can be run as a service.
