Overview: 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 like phone number spoofing. 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.

How It Works…
We use SIP to stop unwanted traffic from entering your voice
network
The Voice Spam Filter relies on modern Session Initiation Protocol (SIP) digital communication. It examines the signaling information transmitted with the SIP call to identify the caller ID.
Within one second, the filter checks the caller ID against enterprise allowlists and blocklists, as well as dynamic robocall list(s) and, optionally, a phone number spoofing call detection system. Allowlisted calls are passed through. Blocklisted or suspect calls are diverted to a recording, filtered through the Mutare CAPTCHA, or simply disconnected based on rules set up by the system administrator. Call screening is typically completed in under a few hundred milliseconds, making the system completely transparent to callers and your employees.
