Asterisk, the opensource telephony solution

Asterisk is a software that turns a computer into a complete communications solution. With Asterisk we can develope an Asterisk PBX, a voice converter VoIP, Call Centers, voicemail, fax, and virtually anything you can imagine related to telephony. Asterisk is an open source project sponsored by Digium.

GRN uses Asterisk for all the voice solutions we offer. We assenble this software in a Supermicro server (or similar) with Digium, OpenVox or Bernonet telephony boards and SNOM or Cisco phones.

Openenergymonitor, monitoring energy power

The openenergymonitor project was born to achieve an open hardware platform to measure a reliable and affordable way the energy consumption in everyone home or business.

One of the projects we’ve been doing (in this case Esteve) is a system integrating the Raspberry Pi and openenergymonitor, you can see it here (in catalan).

Raspberry Pi, a lovely and geek product

The non-profit Raspberry Foundation from UK has designed and produced a low-cost computer for educational purposes. The importance of this project is that you have a complete computer (albeit low power) around 30 € + VAT.
The Raspberry Pi user community is growing dramatically and is becoming a device for all types of inventions. See for example the Adafruit blog.
GRN is playing with the device from the beginning (also on sale at the shop) and we are using it for various projects, follow our blog and twitter and see the possibilities you have.
