I had an interesting experience at a recent meeting with a local government agency. The subject of purchasing Internet and advanced communication services came up and the customer mentioned that of course they wanted to go with a tier-one carrier.

We ran into a rather bizarre problem a while back with a VoIP installation. The installation consisted of a cisco 3560 48-port PoE switch feeding 35 Polycom phones.
