Even, if I'm not obviously working for Nortel ;-), some info:
DNIS, Dialed Number ??, is the destination phone number a remote user
is dialling to
CLID, Calling Line ID, is the source phone number a remote user is
dialing from
It is fairly common for NAS, Network Access Server, (the large routers
with 100's or 1000's of modems), to use both the DNIS and CLID to
perform some 'authentication'.
E.g.:
- some ISP are sharing the same big NAS and using the DNIS to differentiate
calls to ISP#1 from calls to ISP#2
- refuse calls coming from unknown CLID
- ...
CLID and DNIS are:
- provided by the Telco (and not 100% trustable -- the Telco could be
hacked)
- available on most NAS from most vendors by SNMP or RADIUS or TACACS
