Answerphone detection also allows the system to determine whether the voice answering the call is a human or a voice mail service and can play a tailored message and update reporting as necessary.

The voice platform can deliver approximately 600 simultaneous voice calls (can vary depending on the telephone network’s capacity in the chosen area and the length of the voice message).
