I have had my toll free lines thru Inter-Tel for a long time. A few years ago they were bought out by Mitel. Or Maybe they were always Mitel, but something changed. Anyway, they have started to become like AT&T was to deal with and I am seriously considering shopping for a new toll free provider.
Does anybody have any suggestions? Reasonable instate charges. (Arizona) Sub minute billing, low or no per line maintenance fee. Clear quality lines (not over driving their bandwidth, no tin can, or echo on lines)
