Noob Needs Help w/ Blocked Outgoing Calls

Question

I'm very unfamiliar with this technology, however, I've been put in charge of it.  We're using Cisco Unified CM Administration v6.1 and currently we're unable to make calls out to any 900 or 330 prefixes and I can't figure out why.  We've called our telephone service provider and they were able to call from their lines, so they are suggesting it is something on our end.
The only thing I can think of is the CM, however, I'm not sure where to even begin looking.  I did a little research on Google and started checking the Route Filter, however, I wasn't sure if that is where I need to be. (I thought for a minute that it must be true if it was on the internet :-) )
Anyway, my question is, can anyone shed some light on where I might find some settings that would be blocking us from calling out to these numbers.  Area codes 330 and 900 are honestly cell phone numbers and we can't 7 digit dial or even 10 digit dial these numbers.
Thanks in advance for your time and I really appreciate everyone for their help.

1. He means what is your protocol i.e. SIP, H.323, etc.  If you go to device ---> Trunks and search for everything you should be able to find the gateway your CUCM is pointing to.
2.  There needs to be some sort of route pattern pointing to your gateway or no calls would complete.  Call Routing --> Rout/Hunt ---> Route Patterns and do a blanket search. 
3.  Your gateway config which is your router, CUBE, or whatever you may be using.  Issue a "Show Run" and post the contents here.
4.  'Debug ccsip mess' is the command from your gateway that you can use if you are utilizing SIP trunking.  This will provide information such as INVITE, TRYING, ACK, RINGING, etc. with much more information telling us what is going on.  All of this needs to be posted here for us to be able to help you.  Understand this is a very difficult situation since you are extremely limited in knowledge on the systems.
