We purchased two phone systems with multiple phones and a video surveillance system from Greg. We eventually switched our 12 lines to the VoIP phone lines. I was very pleased with his work and he has great knowledge in what he is doing. The cost of the equipment was reasonable and his labor charges are one of the lowest around especially taking into consideration the high quality work he performs. I would call it "top of the line". His work is very organized, well marked with no confusion, neat and clean with no messes left behind. Greg is also very timely in getting back with me and is usually able to get to us within 1-2 days. I would highly recommend Greg and his company for any phone system, network cabling, video surveillance and/or VoIP phone lines you may need.
