[Asterisk-Users] quad t1 / 1U rack server combos

[Cory Andrews]

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.
