Even if this was a major problem, thats why CallManager has fairly
robust clustering support.

Referring to CM as clustering is a serious misnomer. If your primary
dies, the phones will fail-over to a secondary (or third), but some
functions will no longer work. For example corporate directory, music
on hold, etc. Depends on your setup, but the point is that not all of
the phones functions have fail-over if the server providing that
function dies.

Like you said, it depends on set up

You can set up multiple tftp servers with mirror images from the publisher.
You can do the same thing with the directory and services. If you want to
really get into it you can set up multiple servers behind a load balancer.
You can put in as much redundancy as you want on top of whats there by
default.

The Call Manager application is stable and works well. People need to stop
hating it because it's Cisco.

Many IT people simply don't know any better. Many of us also jump on the
VoIP bandwagon without having a clue as to why. There are a lot of
misinformation regarding the "benifits" of VoIP and the best application of
the technology (where appropriate and cost effective).

I agree that there are many things to look at when thinking about VOIP. We
install what we think fits best.
I will say that VOIP is being installed more often now and is not excluded
on any project. VOIP is the future though.
Even Nortel is trying to push it on us.
