This is sounding exactly like the same kinds of silly planning/costing
issues that creep up when developing VoIP solutions.
* central PABX + central, large scale battery deployment
* satellite PABX + smaller, satellite battery backups
* everything gets x hours battery backup
* periodic PABX battery tests and replacement
* "PABX Is Expensive!" so money is (hopefully!) spent keeping
the failure-mode infrastructure tested and updated.
* (De)centralised VoIP infrastructure
* All switches, distributed throughout the network, require
* .. at ~ 6W for some of the handsets, and > 6W for some of
the gigE cisco handsets..
* Network design typically forgets to separate desktop and
VoIP infrastructure (since Cisco/etc sell you unifying them!)
and thus everything needs to be backed up.
* .. so UPSes in every wiring closet? Hah.
* .. and then even if that's done, small bits tend to be forgotten
until the first scheduled test of the failure systems (if they're
: eg, media converters connecting to upstream ISP (eg that box
hooking you into Amnet/Optus)
: eg, that unknown router acting as a gateway to your DNS
infrastructure, which your VoIP infrastructure uses ..
Ah, fun times. As much as I'm glad I'm a spectator here, sometimes I really
would like to be involved in this stuff again.
