[Asterisk-biz] Need Advice

[Michael Welter]

I need to place a SIP FXO gateway in Central America.  I've been looking 
at Quintum products, but the prices are about $150/FXO port.

I have a Dell SC400 on the shelf, and I'm considering just installing 
Asterisk and two TDM04B cards and shipping it down.  Does anyone have 
multiple TDM cards in the SC400?  FXO ports on a TDM card are about 
$75/FXO port.

With the Dell, there will be the advantage of trunked IAX (we're paying 
for bandwidth on both ends).

Can anyone tell me if I'm missing something.  The mains are 110V.  What 
about answer and disconnect supervision (I'm assuming there isn't any on 
the FXO circuits).

Is there some other way to do this for around $500?

Thanks for your help,
Mike
