Next level

Hi! I’ve been playing around with Asterisk for some time now! Up to now, I’ve been strictly using soft phones (in addition to my nokia E60). Now, I want to go to the next level, and connecting a “regular phone” to my asterisk. A little word about my setup, I have a wlan card (which I use for my inet connection) and a lan card which I hooking my DRG11 to (42networks.com/products/drg11_22.html). Now i am a bit lost, how do tell asterisk to listen to the lan card?

-kudos
(sorry if the above was confusing, but so am i)

Asterisk usually listens on all of the interfaces. What does the following command show?

netstat -anp | grep asterisk

It is listening on all of the interfaces if the local address listed is 0.0.0.0
