Dialed Number Identification Service, "dee-nis" digits or just
"digits" in telcospeak.  They're used to route calls.  E.g., a company
may have 100 phones on its PBX but expects never to have more than 24
in use at the same time, so it has only one T1 (24 lines).  When a
call comes in, the digits identify which phone was called.

Saying DNIS could be hacked is like saying the destination address of
packets you get isn't trustable because your ISP's router could be
hacked.  It could happen, but it's not likely to be the first or worst
consequence.  You'd have bigger problems than incorrect DNIS.
