[Asterisk-Users] PRI with variable length numbers

[Martin Pycko]

Why do you see the problem with that ?

How would you use that functionality that analog channels have ?

With PRI you're going to always receive the full number that was dialed.
So since you have a limited number of DID's do the matching one for one
and it'll work.

Martin
