[Asterisk-Users] 5,000 concurrent calls system rollout question

[C F]

I don't know how much 1+1 by you is, but lets recalculate this for a moment:
First the bandwidth per channel:
http://www.airewaves.com/aire/support/bandwidth_explain.php
1.5mbps (mega *BITS* not BYTES per second) to a full T1, which equals
1536 Kbits, each channel then takes 64kbps.
64*5,000=320,000kbps.
32,000/1,024=312.5 Mbps (round off to Mbps), no where close to a Gb.
Every single PC made in the last 4 years I came across, can handle
this type of bandwidth.
BTW, this all amounts to just over 39 MBYTES per second. 312.5/8=39.0625
