Hello, i just installed a Connectiva Linux on a PC and want to know what i need to run Asteriks. I already have two Sipura SPA-2000, a network, a router and a adsl internet. - To connect to the network/internet i need only one ethernet card? - To connect to the PSTN i need a regular modem? Can i add more to have more connections to the PSTN on the same computer? After that i only need to get more ATAs to use as "braches" of my system? Thanks Tony
