After working with NEC systems for more than 10 years, both as a technician and as an end user, I can say with confidence that their stuff just doesn't break. Period. You can kill it by installing it in an unventilated phone closet, outside and exposed to 110F degree Fresno summers, but even then I've seen NEC's in those environments last for 10+ years!
Yes, the proprietary PBX stuff is very resilient. The only time you really need a backup is for power supplies and components that have HDDs. The usual suspects: heat (power supplies) and moving parts (HDDs) are the culprits. That all being said, the advantage that Asterisk (and other OSS telecom platforms) offers is the ability to remove significant cost from the equation. If you can afford a box that can run Linux (and the requisite telecom hardware, if applicable) then you can get a very inexpensive PBX up and running. Keeping good backups of config files is the best way to prevent long downtimes. If something is mission critical then a business would also invest in having a hot spare or something else "on the shelf" in case of an emergency, like a spare HDD or two, a spare box pre-configured, etc. <pontification> Bottom line: Proprietary PBX vendors make rock-solid stuff that runs forever, but you pay for it up front. Asterisk runs on lots of different systems, some of which may not be rock-solid, but you still have freedom of choice, and THAT is what OSS is all about! </pontification> -MC > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:asterisk-users- > [EMAIL PROTECTED] On Behalf Of Douglas Garstang > Sent: Wednesday, October 11, 2006 2:56 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: RE: [asterisk-users] How big is *your* dialplan?? > > > -----Original Message----- > > From: Andrew Kohlsmith [mailto:[EMAIL PROTECTED] > > Sent: Wednesday, October 11, 2006 2:00 PM > > To: [email protected] > > Subject: Re: [asterisk-users] How big is *your* dialplan?? > > > > > > On Wednesday 11 October 2006 13:23, Douglas Garstang wrote: > > > No one's system is redundant? :O > > > > Is your Norstar MICS redundant?
