[Rafael Visser]

Hi Guys...

I  allready made a trial of the leibct/sangoma solution tcap/map for
ati purpose, no problem at all. quick installation, easy to use, very
cheap. This solution can be found on sigtran too.

You can find them at www.leibct.com  or   aleib at internet.com.uy

I hope this info will helpe someone
