You must use FXS interface.

I recommend you engage a reputable consultant or UC certified Cisco partner. Otherwise, you will not get good results, and waste many hours in frustration.

For example, using only FXS interface will cause two-stage dial, and is not recommended. So, it's not as simple as it may seem.
