A good internet connection is an absolute necessity, obviously.

Not enough attention gets paid to network infrastructure INSIDE the building, though. It's really a must to have managed switches, not the $49 box from the big box stores to manage and properly route network traffic, with special attention given to voice traffic with VLANs created when necessary. Our salespeople learned this lesson the hard way after selling hosted VoIP to Mom and Pops with simple 4 port dumb switches. Unhappy customers always crow louder and longer than happy ones do.

Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
