The classic PC-based internet answering machine has largely been replaced by cloud voicemail and VoIP apps. Today free and paid services deliver voicemail, transcription, and call routing to phones, email and web portals.
Call forwarding routes a single phone number to other devices so callers reach you where you want. Modern options include conditional rules, simultaneous ring, and VoIP-based routing.
VoIP transmits voice and video over the internet, offering cheaper international and business calling. Learn what you need, how free and paid options differ, and practical limits like emergency calling and call quality.
