[asterisk-ss7] How many spans ??

[Marcelo Pacheco]

Someone in the list said a couple of months ago to be running chan_ss7
with 8 E1.

As far as interrupts go, using 4 single FXO cards on a system generates as
many interrupts as 4 quad span cards. I have before run with 4 TDM cards
on a single Asterisk system, but with less than 60 channels (3 TDM400P +
E100P).

I believe that with an efficient quad CPU high end system with hardware
assisted transcoding (digiums G.723/G.729 card), even 16 E1 will be
possible as long as your dialplan is simple, or you have fairly long calls
in average.

8 E1 with the right CPU/mobo combo and G.711 only should be doable today.
