Depends on hunt groups and such. If you have rollover/hunt groups,
pointing a 1800 to a number is not very useful for getting DID or DNIS
functionality. 

The different context solution was based on the idea of making each
incoming analog line have it's own logical seperation in the dialplan.
The trouble is, as you roll from one busy line to the next, there is no
information about what group the person dialed into. If you where to
split your hunt group into 2 - 4 line groups without talking to the
telco, you could fill group 1 up and then be rolling into group b. Same
works the other way with wrap around hunting.

If you don't have hunt group functionality, and you point a 1800 number
to a analog line, then the second phone call will hit a busy signal.
