this is how it was explained to me by Matt in another thread:
In short, here's what you do:
1) Make the PDN of the phone a non-DID; you can still have rollovers, FDN/HUNT/LHK, etc...
2) Build the DID number as a CDN
3) Acquire the CDN in Symposium / CCMS and add it to the Master Script; point to its own Primary Script
Assume the DID is x7580
Assume the non-DID you assigned it is 6580
That primary script should say something like this:
IF CLID = 3105551212 THEN (the number you want blocked)
GIVE BUSY (or DISCONNECT, or whatever you want it to do)
ELSE
ROUTE CALL 6580
END IF
That will screen the calls for the CLID of 3105551212 (calling number) and if that is the number that called, then it'll give it busy, or disconnect; whatever you want.
If it's NOT that number calling, it'll route it to the phone.
It's really messy....
Thanks,
Buddy
