After it is setup on your wifi network and the software is configured, talkiepi will require little to no maintenance to use. talkiepi runs a mumble client that has been designed specifically for push to talk via the push button interface. Talkiepi is built utilizing a Raspberry Pi, USB speakerphone, some basic electronic components, and a 3D printed enclosure. There are already software clients for all platforms (Mac, Win, Linux, IOS, Android), meaning you can talk with your talkiepi using your phone or computer, and you're not limited to just talkiepi devices! By utilizing Mumble channels, user registration, and access control lists, you can configure different groups of talkiepis, just like using different channels on a traditional walkie talkie.

Mumble lent itself perfectly for this use case. Mumble is an open source, lightweight, high quality voice chat system designed for use by PC gamers. Talkiepi uses Mumble for its voice communication protocol.

When you push the button and talk, all the other talkiepis in the channel will hear what is being said. It provides a very simple 'push to talk' interface. Talkiepi is a wifi 'walkie' talkie for your kids and their friends.
