Voice92

Voice92 is a voicemail and missed-call alert service that gives any phone a private number of its own. When a call is missed, Voice92 turns it into four things at once: a recorded voicemail you can listen to online, a text (SMS) alert, an email, and a written transcript of what the caller said. Nothing gets lost, and you can see who called and what they needed without playing phone tag. What makes Voice92 different is that it works on every phone. There is no app to install and no smartphone required. It works on modern smartphones, on basic flip phones, and on kosher (content-filtered) phones used in many religious communities — the same phones that usually cannot run voicemail-to-text apps. You keep your existing phone and number; Voice92 simply catches the calls you miss and delivers them the way you want. Key features include: - Voicemail to text: every message is transcribed into readable text, in English and in Yiddish. - Missed-call alerts: get an instant text and/or email the moment you miss a call, with the caller's name when it is a known contact. - Voicemail by email and SMS: listen to the audio, read the transcript, or both. - Contact list and caller ID: name your callers so alerts show who is trying to reach you. - Custom greetings: use the built-in greeting library or record your own; higher plans add scheduled and AI text-to-speech greetings. - Block unwanted callers, export your voicemails, and share access with family or staff. Voice92 is built for people who miss calls and want a simple, reliable way to catch every message — busy business owners, families, and anyone on a basic or filtered phone. Plans start free, with paid tiers that add text alerts, audio delivery, and full transcription. Setup takes minutes: forward your missed calls to your Voice92 number and start receiving voicemail, text, email, and transcripts right away.
