Which is a different billing schema, and is NOT based purely on area code. You can call 352-269-XXXX from 321-436-XXXX and it could be Inter or Intra since they are in close proximity to one another, and the only way to know is if you have a copy of the database showing this relationship. Since this database is proprietary, that's a bit tricky.
That being said, if you have no fear of this situation (which, BTW, can be a HUGE price difference!), then LCR is not a big deal.
LCR can be handled in the dialplan using either excessive extensions representing the dial path for each area built to Lowest Cost for each possible path (excessive, like I said, but fast), or excessive key pairs in the asterisk berkeley database or in a mysql table. More often it is handled in an AGI script which hits a mysql table (or another data method, as AGI scripting is in perl or php and can use any scripting method you like to make the decisions). Some will execute this outside of the Vicidial system by passing calls through an LCR server which may serve other functions (such as recording all calls for legal purposes).
Often the carrier is actually a "broker" and already using LCR (since every percent of a penny counts when reselling minutes at an 8% margin ...).
So LCR can be implemented at several levels and for many purposes.
