As RBF noted "Not everyone can afford to play in this arena however." Therein is the problem.
How many mom & pop stores, gas stations, churches, delis, restaurants and such can afford to get into a managed VOIP service situation? Local loop charges alone are enough to keep small outfits away.
Managed services seem to be fine for medium to large corporations with multiple locations that need to be linked. Having an IT person on staff is a real plus.
The little guy is relegated to the Vonage or Packet 8.
