Karl, We have Mitel IP controllers, tied with IP trunks between them. I think ours work very well, but I did the work, so I may be biased.... VoIP is great, as long as you understand what it takes for a successful implementation. I am not a big fan of the hybrid systems, simply based on the way most of them communicate. I know some people would argue with me on that one, so I would be more than happy to explain that one if somebody is actually curious... :) The key to VoIP is QoS and solid connections. VoIP uses little bandwidth, and if prioritization is in place (DSCP, VLAN QoS, etc.) you should not run into too many issues as far as the IP communication is concerned. One thing that can be an issue is the quality of the land lines coming in. We do not have a T-1 (PRI) yet, so like most schools we are relying on the regular CO lines coming in. Any issues you have with these will be amplified with an IP based system. All of the IP based systems I have dealt with have line measuring tools to compensate for this, but if they are not run, or are not used correctly, you can have issues. This will not be an issue with a T-1 or a PRI. Probably more information than anyone wanted... :) Jim Kerns, Technology Director Spencer Community Schools 23 East 7th St P.O.
