Dial Patterns

In my progression through CCNA Voice I'am now in pretty deep into CUCM and UC. I have phones setup that can ring each other and end users with voice mail and even managed custom wallpapers and ringtones. I just finished the setup of MGCP on my gateway router and it has registered the FXO port and Im ready for the next step. I just started into the dial pattern portion and want to make sure I do it right. Correct me if Im wrong but you configure the Route Group--> then Route List--> then Route Pattern. I have had in my CME lab a dial pattern of 91[2-9]..]2-9]...... work for out going calls using loop start. I tried that as a dial pattern in CUCM and you can dial my cell phone number and the FXO port lights up and the call says that the number is not in service. What would be a bare bone basic route pattern to get me up and calling out through CUCM? Hopefully as I keep watching videos I will come up with the answer on my own but this site has a wealth of knowledge on it.
