[VoiceOps] Geographic redundancy

[Hiers, David]

What with the NANOG list being flooded with news about the flood (http://www.datacenterknowledge.com/archives/2009/08/07/water-main-break-at-key-nyc-telecom-hub/), I figured it'd be a good time to ask....

Has anyone really solved the whole config sync and operational failover issues to provide full geographic redundancy for a hosted voip network?  Failing over TDM DS3s, SS7, IP, SIP, voicemail, IVR programming, etc, such that there is no user-observable indication that failover occured between two calls is the big goal.


Thanks,


David
