About Mutare Voice Spam Filter

The Mutare Voice Spam Filter guards your voice network by filtering incoming calls, allowing legitimate business calls through while blocking spam callers. Unlike some spam solutions that ring your phone and interrupt your workflow, the Voice Spam Filter is designed to divert spam calls without ever ringing your phone. Because voice calls are the life blood of business, the feature was designed to “do no harm,” stepping out of the call path in the event of a failure and never “listening” into the call medium. The filter simply looks at the call signal data ensuring call integrity and security.
