[asterisk-users] how many quad T1 cards

[Benoit]

Isn't anyone using this kind of thing http://www.red-fone.com/ for this
kind of massive HA deployment ?
there is a case study on their web site using 4 asterisk boxes and 8
red-fone T1 to Ethernet bridges to
handle 900 concurrent calls.

(I would say that using all this nice hardware on Linksys network
switches is kind of shooting itself in the foot,
but that's another problem ...)
