I agree completely, but I'm seldom the one paying for it. It is very inexpensive to use existing cat3 voice cabling, coupled with a $100 switch, to build a totally dedicated voice LAN. The only costs at each desk are the cost to install a new rj45 jack in place of the rj11. At the MDF, the cross connect panel simply needs to be patched into the switch. For a few years it will still be the case that smaller system deployments (less than 50 phones) will be up against traditional PBX solutions (in Canada, that often means re-using existing Nortel sets), which can re-use the existing wiring. To compete, a solution is needed that will keep the costs in line with the competition. As soon as you use the term Cisco, I am at a loss as to how that can be achieved.
