Spam Call Blocking and Number Rejection Rules

Automatically handles unwanted or spam calls by implementing rejection rules based on caller ID, number patterns, or blacklists to prevent unwanted calls from reaching users.

This feature automatically handles unwanted or spam calls by implementing rejection rules based on caller ID, number patterns, or blacklists. Moreover, the protection system prevents unwanted calls from reaching users through intelligent filtering. As a result, your team can focus on legitimate business calls while the system handles automated response actions.
