Could you perhaps do a check for callerid pattern and use that as the 
lookup key by rewriting the attribute in the request?  Not sure if it's 
possible to rewrite the username, but changing the password to a defined 
value such as "password" should work I think?  Would satisfy the CHAP 
request anyway...  Unless it's possible to have radius ignore the 
password with an Auth-Type response

Not got a spare sim to test with at the mo, can't see why it isn't 
doable though
