[Asterisk-Users] Asterisk in production as a fax server, anyone?

[Paulo Scardine]

I have a worst issue for you... If your fax solution is ever going to 
receive fax in Brazil, how would you block collect calls?
I have made a fax server solution with cheap Digium hardware that works 
in Brazil (2 E1s).
