i installed mitel for several years, but pre-voip. if mitel could do my total network solution i would go that way. we sell cisco, gold partner or something. you can not beet their routers or tech support. i love the ccm but am not to hot on their voice mail. my opinion, mitel is trying to learn data, cisco is trying to learn voice. nortel hasn't got a track on voip yet, yes, you can but it, no you can't find anyone to make it work (almost anyone) imo, it's all scaleable, i could take two dozen ccm's and put 50k stations on them. without tdm i wouldn't want to pay for the bandwidth.. good news bandwidth is droping in price.. the reason tdm is still selling at all is dependability, 90 percent of the usa picks up a home phone and heres nortel dialtone. i would love to switch to solid voip at my site, 8000 station hospital, but when some prewire tech unplugs a switch in 3 west and kills all the phones in the or's. i'll be looking for work, today we expect servers to need a reboot, system x will be off line from 1 to 1:30, daily email. try sending one saying the voice server needs a reboot... if i was making the decesion, voip only option on the table.. solid cisco network, cisco call managers, redundant.. (dell blade servers) i can turn off my ccm, (behind a nortel 81c) and the cisco wireless users (300) never knew it happened. everything on the cisco side it totally redundant, peer to peer networking is unreal, almost like free bandwidth. running dual pri's to dual ccm's, but cisco to cisco if pure voice over, cisco to network uses the pri tdm, with clid and name display.. clean.. i helped with the design, and did the software on the nortel side, the cisco side was handled by a ccnp in about 4 hours
