When an incoming call starts ringing, the UBlocker instantly connects to HQTelecom’s cloud server to check if the caller’s number is registered in any of the lists (Global Blacklist, User Blacklist or User Whitelist). If the call is in any of the Blacklists, the calls still get disconnected within 1-2 seconds.
