Hi again. My last post was incomplete, so I' reposting it. I've seen that each country has its own PSTN qualities. I would like to know the minimal characteristics needed in PSTN to use Asterisk and also if some body knows which are Spain's PSTN's. I'm interested in buying a TDM card (probably a TDM11B card) and I need to know if it will fully work on Spanish PSTN and what features I might have available. Thanks. RODOLFO --- avast!
