Question on Audiocodes MP104

Hello There,

I’m new in this VoIP arena but are really interested in learning more.

Could you tell me more about this:
Audiocodes MP104-FXS/AC/H.323-3, 4 channel analog (FXS) H.323 gateway

If I were to purchase this box, can I just plug it in to my regular analog line and make a phone call to any phones and the traffic will be routed through my DSL line?

Or do I need another components to make it work.

Your advice is highly appreciated.

Thank you,

Andy
