Wouldn't the point of having a primary and a failover be for redundancy?
Wouldn't purchasing such a device for this configuration void that by
putting you back to a single point of failure?

The foneBRIDGE is not marketed competitively against Digium or Sangoma
4T1 cards. It is designed specifically for folks who have redundant
Asterisk servers, so that you don't have to purchase a Quad T1 PRI card
for both your primary, and your failovers.
