COMPREHENSIVE VOICE SECURITY FOR WEBEX CALLING
Call Reputation Intelligence
Allow, Challenge, or Block Calls Based on Risk & Policy
Bring real-time call reputation intelligence for Webex Calling to automatically allow, challenge, or block calls based on risk and organization-defined rules.
Superior Voice Security
for Webex Calling
Voice Traffic Score (VTS) protects inbound voice traffic for Cisco Webex Calling.
Every inbound call is evaluated and assigned a risk score, enabling organizations to automatically allow, challenge, or block calls based on policy.
VTS helps reduce unwanted traffic, improve productivity, and strengthen voice security through a simple, cloud-native approach designed specifically for Webex Calling.
Together, Reputation Thresholds and Custom Rules give Webex Calling administrators broad, automated protection with precise policy control.
Reputation Thresholds
Protect at Scale
Automatically determine how inbound calls are treated based on your established Reputation Thresholds.
Custom Rules
Control the Exceptions
Override Reputation treatment for specific inbound calls that require specific control and handling.
2 Complementary Controls
Establish how Webex Calling handles inbound calls using two complementary controls:
- Reputation Thresholds establish broad, risk-based policy.
- Custom Rules provide precise control over specific inbound numbers.
