[asterisk-users] Modem

[Carlos Ruiz Diaz]

You understand perfectly fine the situation :) . I'm not saying that
Paraguay has the worse economy in South-America, but we need to work much
harder to get latest technology or to mount a tiny/small laboratory.

You will get amized if you see the things that we have done with pieces of
hardware considered as garbage in USA :D

market in Paraguay, I wonder.

Yes, they changed their name to Copaco for Compania Paraguaya de
Comunicaciones. It's basically the same company ruling the whole country. :S


Thanks to all for answering my question.
