VoxGuard's answer
VoxGuard has a unique 2-phase screening approach. The first is a custom key phrase defined by the user that the caller has to repeat, removing 100% of robocallers. The next is asking for the caller's name and reason for the call, which allows the user to listen or see a transcription of the call. Contacts come through as normal. VoxGuard also offers a custom voicemail seporator for unknown callers vs. contacts, with either voice recording or Text-to-Speech for better anonymity.
VoxGuard's answer
Most services on the market just block calls labeled as spam, with genuine callers being blocked. Others let every call ring through asking for a call reason interrupting your day. With VoxGuard's unique 2-phase screening approach, only verified, real humans ring through.
