Back in the day we used to be able to dial in and connect to stuff, check for power on and the likes if a site was all messed up.
We have a remote site that is modern, cisco voip phones and the likes.
Today, how do you put in a emergency only infrastructure that works when the other stuff is down ? Can we cut a line out of our broadband and use it as a dedicated separate firewall / router infrastructure ?
I am going to ping our isp and see what they say but I am looking around.
