Setup of the Voice Bridge is simple, provided you have a wall jack for a phone near where your Internet router is located. All the necessary wires/cables are provided with the Voice Bridge. You have to connect the Voice Bridge to the phone wall plug, to the Wifi router, and to the power. If you get phone service through broadband (your cable company), you can connect to the broadband router telephone plug. There is also a splitter provided in the event there is already a cable in the jack.
After your Voice Bridge is properly connected, it is time to discover the device from your phone. This involves downloading the Voice Bridge app from Google Play or Apple's App Store and running it. The initial discovery must be done while both devices are on the same home Wifi network. After a couple tries, the Base Discovery option worked for me. If at first it doesn't succeed, turn off Wifi on your device and reenable.
The instruction booklet provided has setup instructions in five languages, none of which are Chinese. You can actually clearly understand them and the illustrations are clear. Besides English, you have Spanish, French, German, and Italian available. Oddly, the external box only has things in four languages, leaving out Italian.
One other thing I should add is the box includes plugs and phone jacks for just about every place in the world. You'll be able to use this thing nearly anywhere that has a network and phone jack.
Overall, I like the Invoxia Voice Bridge product. It is all a question of need and if it is worth the $99 cost. Many people have done away with their landline totally so clearly this isn't for them. If you have bad mobile coverage in your home, this would allow you to keep using your mobile in your home and you can also pair five different devices to the bridge so you're not limited to just one. If you have a need for what this device offers, you certainly won't be disappointed. For you, it allows you to stick to one device, your mobile, for all calls basically. For your friends, it allows them to only have to call one phone number, your home line, to get you, no matter where you are.
