Yeah, whole different scenario with a human agent vs. an autodialer.

Presumably these are agents with a SIP trunk to a telemarketing system
and not generic business users.  With the Sansay you can deploy a
blocking server based on the resource, so 911 and other service codes
would not use it, only NPA-NXX-XXXX.

If the trunk is used only for outbound telespam^H^H^H^Hmarketing, then
logically you would probably want to reject on unreachable.  Sansay is
pretty flexible in terms of ability to use multiple blocking servers.
