The Voice Security Platform

The Voice Traffic Filter Dashboard provides a visually dynamic, graphical overview of call activity and filtering actions applied for both inbound and outbound calls over specified date ranges. Interactive dashboard elements and tallies provide a clear breakdown of wanted/unwanted call volumes by filtering layer, with one-click access to expanded call data reports.

Voice Traffic Filter’s visual, data-rich dashboard enables admins to quickly identify patterns, trends and changes in their network traffic, providing critical intelligence needed to optimize flow and performance.

The Voice Traffic Filter Control Panel includes configurations establishing the actions the system will apply to both incoming and outgoing calls, as well as configurations for each of the available filtering options.

Left side displays current settings for each filtering layer in order of call flow from first/last filtering action. Admins can open and edit configurations for each filter layer through edit tools on the right.

Threat Radar consists of three distinct call surge detection systems designed to recognize call patterns consistent with a potential spam storm or spoof attack. Threat Radar applies a combination of analytic processes, machine learning, and AI to detect and, when warranted, deflect these disrupting or potentially malicious calls based on specific behaviors and number patterns that are outside of the organization’s normal voice traffic activity.

Administrators can set their own Threat Radar configurations or simply choose to apply recommended system default settings.

STIR/SHAKEN is a set of FCC standards for digital caller ID authentication using digital certificates to verify that calls originate from legitimate numbers and are not spoofed. Mutare Voice Traffic Filter includes integration and analysis of STIR/SHAKEN attestation trust scores passed through from the carrier.

Administrators can select call handling actions based on the telephone number verification provided via the verstat URI parameter as well as the P-Attestation-Indicator parameter in the call SIP headers.

Mutare’s Voice Traffic Filter’s Proprietary Dynamic Database is a continuously-evolving hard line of defense against known spam, scam, and vishing attack campaigns. It taps into multiple worldwide resources dedicated to tracking and verifying tens of millions of numbers related to nuisance and nefarious call activity, and then assures those calls never make it into the organization’s voice network.

Configuration for the Proprietary Dynamic Database allows admins to determine what actions (Drop, Route, or Send to Voice CAPTCHA) the system will apply to calls that match numbers on the database.

Designed to “do no harm,” the Voice Traffic Filter includes the ability to route all calls or those flagged as suspect through a voice CAPTCHA for additional vetting. The system prompts the caller to input a random set of digits before passing the call through, effectively separating bots from humans.

Administrators can determine how many digits the CAPTCHA requires and how many seconds and tries the caller is allowed before the test is treated as a fail and is dropped or routed to another resource.

This Call Activity page includes a log of all calls identified by Timestamp, Call Direction (Inbound/Outbound), Caller ID (Caller Number), CNAM (Caller Name), Called Number, Action, and Reason for action. The display can be filtered by date/time range and through an extensive filter set for more refined results.

Each call log can be expanded to reveal full SIP header details as well as what filters were applied and in what order. Reports can be exported as a CSV or JSON file for offline analysis.

Custom Rules is a highly flexible, organization-specific blocklist and allowlist builder and management tool that applies customized call handling actions against matching calls. Rules can be built around a combination of Caller and Called Party IDs or CNAM, and can be applied to both incoming and outgoing calls. Admins select what Action (Allow, Block, Route) to apply to each Rule.

The Custom Rules page shows configurations for each Rule created, including direction, type, action applied, to/from numbers, a tally of matching calls, description, and date the Rule was created or updated. Admins can add new Rules or open and edit any existing Rule configuration from this page.

This feature allows individual users to flag phone numbers from nuisance callers (robocalls, solicitors, spam calls, or any other caller that is an unwanted intrusion on their business phones) and add that as a Block rule to the Voice Traffic Filter Custom Rules set.

The Blocked Callers interface displays details including when blocked calls were created and, going forward, a count of call attempts to the user’s number from the blocked caller.

On this page, administrators enable/disable email notifications for Personal Blocklist welcome emails, Daily Summaries of Traffic Filter Activity, and Alerts triggered through Threat Radar.

Each alert or notification type can be enabled or disabled individually, and multiple individuals can be assigned to receive specific reports.

Built-in telemetry security tool automatically extracts, formats, and delivers logged voice channel data to the organization’s network security platform (e.g. SIEM).

Extracted data set can be correlated with other network activity datapoints for enhanced visibility into network security vulnerabilities and emerging threats.

Included in the Dashboard is a tool that provides an estimate of time/money saved through reduced interruptions from unwanted calls for a specified date range. These figures are calculated against user-provided estimates of lost time per unwanted call and average annual employee salary.

The tool will automatically calculate and display Time and Money saved for the selected date range as well as an annualized estimate of money saved due to the reduction of unwanted calls.
