But that doesnt do what we want. I want to completely ignore what the user
has sent as a callerid, instead overwriting with our choice on a user by
user basis.

If we have a user [a] & [b] in iax.conf and we set:

[a]
secret=password
callerid="2125552222" <2125552222>

[b]
secret=password
callerid="2125554444" <2125552222>

and then just use exten => _1XX,1,Dial(ZAP/${EXTEN})

This works wonderfully *unless* the IAX call has a NULL caller id, in which
case the outbound callerid is NULL. For our purposes we've hacked chan_iax2
to overwrite it with callerid= even if a NULL caller id is passed with the
inbound call.

With this explanation, what is the correct way of doing this?
