see the zaptel.conf and zapata.conf examples at [voip-info.org/wiki/](http://www.voip-info.org/wiki/). Also, doesn’t the card itself come with examples?

surely the manufacturer gave you some info ? if it’s truely “external”, how does it communicate with Asterisk ? once you know that, you setup a trunk in the appropriate technology conf file and the appropriate dialplan in extensions.conf.
