The configuration was pretty easy. I have it hooked up to a data module right now. They can even help on the Avaya side if they need to. I am about to go to the S8710's so my data mod's are going away. I called them the other day to see if they could do an IP connect, and their technical support can even guide me through connecting their unit to the C-LAN board ports.
As for the price, I really dont remember. We looked into all the major players and they had the most bang for the buck as far as we could see. If you decide to go with them, you will not beleive the support you will get. For the first time in years, I dont mind calling someone's tech support.
