[Asterisk-biz] Asterisk Case Studies

[Eran]

We are presenting a new concept to a large company and we are basing our
solution on Asterisk.
In order to convince them I need case studies of successful commercial
Asterisk implementations, both as a PBX and implementation of Asterisk
features in large networks.
Can anyone provide such information or links to Web pages discussing case
studies? (but ones with figures, not general complements...)
