Ive never seen any simulation software for this. There is a good chapter in the IP Telephony Fundamentals book by Cisco Press. There is also a great Cisco Networkers 2005 presentation, but you need an ID from Networkers to see that.

The core idea is that all your devices (phones route points etc.) go into an Internal Partition (Internal_PT)

You then create Partitions for Local, LD, International, E911

Then you place route patterns into PT's for respective class of service (LD, Local, ON-Net, Internal, International)

Then you create cooresponding CSS's that include the PT's you need a person to access

Then place the DEVICE CSS as Internal and the LINE CSS as the one that needs the access:

So
Phone CSS = Internal

LINE PT = Internal
LINE CSS = Local_CSS (this would contain the Local and Internal PT's) or LD_CSS (this would contain the LD, LOCAL and INternal PT's)

Then in your Route Patterns you create items like
9.1[2-9]xx[2-9]xxxxxx
This would be LD dialing and you place it in the LD partition. Now unless you have the LD CSS you can't call this pattern and therefore can not call long Distance.

good luck, there is a lot to this and learning clean Route Plans is a difficult task. Way too much to describe all here. Grab the Fundamentals book (look for the one with the rose cover, not the green) and get a copy of Troubleshooting Cisco IP Telephony (this is still only in the green covered version.
