For the first 2 and a half years of its life, my company has used a Merlin Magix phone system to run our call center. It is an ok little phone switch. It was never designed to run a call center, but the price was right when we got it.
As of last monday we finally stopped using the Magix. We transfered our last 800# to our new call center in Kingston NY. After a week of verifying that everything is good, Keith and I finally shut off the old system today. We unplugged all the ports, and pulled the old thing off the wall. Our computer room looks much neater without it.
Now we need to see how much we can get for it and 50 or so phones.
