Yeah, I am sure you could. I could probably set up an Asterisk server that would meet our needs in about a day.

What I've learned from working for a big company is that they only want to save money if it makes their employees more miserable in some way. An example is turning off the lights and heat at 6PM. This saves a few cents, and makes anyone who wants to stay late miserable. A job well done.

With technology projects, though, the goal is to spend as much money as possible. For an individual to make money, he needs to be promoted. To be promoted, you have to have a big team. To have a big team, you have to have a big project. So the incentive is to make small projects into big ones. The easiest way to get a big project is to buy some Very Expensive software or service, and then hire a team to "customize" it. This way, your line item at the end of the year is at the top, so you must be Very Important and will get promoted.

Also, conference calls already "save money" -- you can have the important business people in the expensive financial centers, and you can have all the programmer monkeys somewhere cheaper, and they can still communicate effectively. (Not really, of course, but it looks good on paper.)

Anyway, this is a long way of saying, I doubt we will use your service any time soon. Maybe if you make it cost more than what we have now, which a separate service like I originally described would :)
