AO Systems Group had converted our office from the old technology phone system with Bell Canada, to a new VoIP based system. He also did some wiring work for new phones and had our new web site on the web in about 5 days. We are also getting a custom designed application designed by AO Systems Group instead of paying heavy, yearly, licensing fees. Very good service, Oliver did exactly what he said he was going to do and inline with his promised quote. Overall, we are extreamly happy to have found someone with such a vast-depth of knowledge and can recommend AO Systems Group, to other's without any hesitation.
