We've been using Nextira for the past few years. Since the purchase by Blackbox, they're sticking to the letter of the service contract (we'll get back to you within 3 days) instead of the idea of service (if you've got a problem, we'll get back to you as fast as you need). I'm looking for a new vendor to provide service and support on a small Option 11C system with CallPilot and Symposium.
Any recommendations?
We're in the Chicago area.
