The Sansay VSXi has this capability.  We haven't deployed that feature
as we don't have customers in that business.  We're happy with Sansay
support and product in all other respects so I presume it should work as
intended.

Should work just fine.  I don't know the default call handling if it
matches a blocked number.  I think that by default it returns a SIP
"Forbidden" response of some type as opposed to an audible intercept but
it may be tweakable to an alternate route that goes to a recording.
