This is the project I’ve been working on for the last two years. Last week we opened it for a few friends, and after checking that nothing has exploded, I think it’s ready to show it to our fellow internet friends.
Puput is service that lets you listen to your emails (and more) for free when you have no internet, with a missed call. We’ve spent some time doing R+D in the telephony field and we saw that the “tone” that plays before a phone pickup can be changed from the server, so that’s what we did.
The product is basically an email inbox, where you can forward important emails using filters. Postfix is connected to Asterisk, and it will misscall you when there is a new message. You don’t pick up that call, but misscall back. Then the server will play a TTS (or a voice memo, if attached) with the email contents, and hang up… without picking up. That way it’s free, internationally.
Our business model is to go for custom integrations, for businesses. We have more complex products which we think aren’t very attractive to end users, but can be interesting for teams: slack integration (call everyone to make sure a message is received), broadcast audio messages with a single call, alert escalation like pagerduty, package tracking using GPS without a data plan… Business don’t care about the residual costs of a phone call, so Puput can also work with regular calls. However, for end users, being free is a good value proposition.
It’s difficult to find which uses are the best fit for a “new” technology, so we are doing a soft launch – data with missed calls is actually new, but it seems we are the first ones to use it in production.
