You know I hate to restate the obvious but Linksys is owned by Cisco and they are making a good switch. The difference between the Linksys switches and the cisco switches is that i dont have to throw all the specs at you and convince you to buy them because quite simply they work. They work very well and QOS is there for voip. The only difference is price points and you as the installer do not have to 23 acronyms listed behind your name to install them. Sorry to be so blunt by I am an old country boy and if I can buy a 3 tine pitch fork for less then a 4 tine pitch fork and still pitch the same amount of hay?????
