[cisco-voip] CCM Reboot Times

[Philip Walenta]

Also keep in mind, there is a perception that five 9's for a PBX means
"everything" stays working.
 
I had an interesting conversation with some ex-Avaya folks once.
 
What they told me was quite interesting.
 
They said that as long as the brains of the PBX stayed active, it was
considered five 9's reliable. Circuit packs, T1's etc going down didn't
count against thier uptime numbers.  So in essence, you could have every
circuit dead on the PBX, but as long as the brain was still ticking, it was
still considered "up", just in degraded fashion.

Getting some very interesting answers, although the norm seems to be once a
month "to fix many issues."  Just curious, what sorts of issues do you see,
does the system start to lose functionality (unable to transfer a call) or
even weirder, like do calls mean for extension B start routing to extension
A?? 

As far as reliability comparison goes to traditional PBX, I do have one site
that must be run 24/7.  So a CCM reboot is going to affect them no matter
how I slice it.  We never had to reboot the other traditional PBX.  I can
certainly live with once a month though!
