Description
Prison Voicemail is a socially impactful venture dedicated to enhancing communication for individuals behind bars and their families. This service allows you to maintain a connection with your loved ones, regardless of your location, by exchanging voicemails that help conserve their phone credit. An impressive 96% of incarcerated individuals report feeling uplifted by receiving voicemails. You can easily reach your Prison Voicemail number from your mobile device at any time to leave a message, which is then immediately accessible on the other end. The prisoners can call their designated Prison Voicemail number from any phone within the facility, with the call costing them only the standard rate for a landline. Once they listen to your message, they have the option to respond or call you directly, ensuring seamless communication. You'll receive notifications through your app, keeping you updated on new messages and responses. This innovative approach fosters stronger family ties and emotional support, ultimately aiding in the rehabilitation process.
Description
TwinPhone is browser-based international calling: a WebRTC softphone that terminates on the PSTN, so you dial real E.164 numbers and the person you are calling answers on an ordinary phone. Nothing has to be installed on their side — no app, no account, no invitation. On your side it runs in Chrome, Edge and Brave, or as a native iPhone app.
How it works: sign up for free, top up a balance with a card, and dial. The exact rate for the number you dialled is shown before the call connects, so there is no guessing between a landline range and a mobile range inside the same country. Rates start at $0.02/min across 145+ destinations.
Pricing is prepaid and per-call. No subscription, no contract, no monthly minimum, no connection fees, no per-seat licence — an account that sits idle costs nothing.
Every call lands in a call log with destination, duration and cost, exportable as CSV. Contacts are stored for quick dialling, and balance, history and account settings live in one dashboard.
Virtual second numbers start at $3.19/mo for US and Canada. Inbound calls and SMS are delivered straight to the browser, which makes them useful for keeping a personal number out of marketplace listings, sign-up forms and verification flows.
On the transport side, media is encrypted with TLS and SRTP, and adaptive audio holds calls together on congested hotel, cafe and airport Wi-Fi instead of dropping them.
For teams, a single shared prepaid wallet covers everyone, with owner and member roles controlling who can invite teammates and who can spend, plus per-member call logs for internal billing.
TwinPhone is operated by a registered company in the Czech Republic.
