I used to be employed by Avaya. We put systems in all the Home Depots, including the wire. Then, we just had maintenance/upgrades on the system, and wiring was sent to BlackBox. Last I heard, BlackBox was doing a lot of the work. Just because you see Cisco phones doesn't mean that Avaya isn't in play somewhere. I've put in several Avaya sip servers with Cisco ip phones working off them. However, what has been stated is true, Cisco bascially gives the stuff away with the networking deals. I did do a site survey at two Home Depots shortly before the Cisco stuff was rolled out. If I remember correctly, there was really no local hardware other then a Cisco router/switch going in, control was in the cloud located elsewhere.
