PRI signalling enables "Network provided" or "User provided"
caller-id. Maybe IAX could implement such a thing.

It's very common in France (at least) :
- the network will provided a guaranteed caller-id
- the user (CPE) may provide another one (usually, a DID number)

and the called party gets both. Unfortunatly, as far as I understand,
Asterisk is not really designed to handle more than one caller id
number.
