[SM] One argument was that POTs switches were getting hard to come by, but I find this hard to believe that generally stated, hard to come by at prices competitive with IP gear might be closer to reality, and clearly the more ISPs switched to VoIP the smaller the market for POTs gear and hence the incentive to develop new generations of switches...
