Is it possible to run a backup server at another location, and if the main location goes down (i.e.: power failure, internet disconnection), the backup takes over automatically and forwards all calls to a cell phone? We just don’t want to have people call the number and they just get a busy signal or some strange error code. The ideal solution is to get it running on a Linksys box or something with low power requirements.
When I had vonage, they were able to forward calls to another number, but I haven’t found another provider that does this.
How have others dealt with redundancy?
