We put cisco phones in about 2 years ago. We are running ver 3.3 on our call managers and 4.0 on Unity with unified msging.
We have upgraded our Unity once and are starting to think of upgrading our call managers to the latest version.
I can honestly say that over the two year span we have had to reboot our call managers MAYBE 3 or 4 times and our Unity probably around 6-8 times. It has actually been a very dependable system with very few problems.
I have worked on Mitel, Inter-tel and Telrad pbx and key systems that had more problems and were not as reliable as this system.
