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. <br><br>
You will get amized if you see the things that we have done with pieces of hardware considered as garbage in USA :D<br><br>> Does Antelco still dominate the telco<br>
market in Paraguay, I wonder.<br><br>Yes, they changed their name to Copaco for Compania Paraguaya de Comunicaciones. It's basically the same company ruling the whole country. :S<br><br><br>Thanks to all for answering my question.<br>

</div></div>This question has been answered many times, but just for the fun of it<br>
I'll answer it again:<br>
<br>
If PC modems had been ideal telephony cards, we'd still be using them.<br>
<br>
My own experience with using modems as FXO devices (long before I became<br>
a Digium employee) was that they were awful. I encountered problems<br>
with echo, half-duplex audio, and lack of far-end disconnect<br>
supervision. All of those problems are solved with most modern<br>
telelphony cards (except for the ultra-cheap cards, which are still just<br>
modems). To put it frankly, I wouldn't wish one of those modems on my<br>
worst enemies.<br>

</div>I understand that the cards are disproportionately expensive in many<br>
parts of the world as compared to the United States, because of the<br>
difference in economies. I spent a couple of years in Paraguay in the<br>
mid 90s, and know what it's like to pay outrageous prices for<br>
specialized electronics just because they have to be imported from other<br>
countries. (I'm guessing that you're from Paraguay, based on on the<br>
monetary conversion you gave. Does Antelco still dominate the telco<br>
market in Paraguay, I wonder?)<br>
<br>
That being said, the cost per port of the Digium cards (or any of our<br>
competitors who design their own cards) is still much lower than what<br>
you'd pay for traditional telephony cards, such as those manufactured by<br>
Dialogic or Aculab.<br>
<br>
I know that probably doesn't help you afford to be able to buy a more<br>
expensive card, but hopefully you have a better understanding of why we<br>
don't use modems as FXO devices. If your time and sanity are worth<br>
anything at all, it's a worthwhile investment to buy a good solid<br>
telephony card.<br>
