I believe the reason they feel it'll pay is they're always moving people around. This way you take your phone with you and plug in at your new location. Bada bing, you're back in business without a phone tech moving your number to where you move.
I think it will all tie into a pbx onsite.
They don't seem to be aware of outages. Everything I need and all interaction is online now. The other morning I was the first one in and it took me 16 minutes to "clock in".
