The Northern Telecom SL-1 (or Meridian 1 if you prefer) can be
configured for either LDN (Listed Directory Number) or PDN (Private
Directory Number) CLID.

For each customer group in the switch a default is chosen as to which
is sent.  Any set can have LDN or PDN chosen to overide this.  In
short; DID numbers can and will appear in your CLID.
