For the most part, we only sell horizontal cabling, frames and racks, and leave the hardware to the clients IT dept for commercial TI's. Although certain phone systems on occasion. Something we can't compete in, so it's often an easy sell to add all the cabling into our existing electrical contract. Funny thing is that more and more systems sales are being done by people who don't pull cable, so it's an easy match.
As for VoIP, same as above, Carrier spec's Horizontal, and shows up with a glorified T-1/2 modem, a Switch and box of patch cords. On the few times so far this is also sold with the network gear, CPU's and MAPI phones. It throws are red flag for me at the start of the job... 'one 5e to each desk...Hmmm RFI!'
Certification on 5, and 5e. Wont go for the 6, and pre-7 meters yet, as of yet there has only been a handfull of places we have even pulled 6. And very rarely do we get asked for certification. And when we do, its often 3rd party. For some strange reason the places that do require it, most have been resturaunt POS systems. Go figure?
IBM 4702 Controller? Not yet, that I know of....
Residential... what-ever you want, like I said, we in the biz of selling wire.
