[cisco-voip] 911 with one way audio (Jason Aarons (US))

[Chris Ellington]

While I've used that as a solution to fixing 911 one-way audio issues, does
anyone know WHY certain destinations, such as 911, 411 etc don't provide the
answer supervision which requires us to use the cut through command below?
The issue you can run into when using that is the CDRs for any calls that
aren't providing proper answer supervision don't work correctly
(usually).

Ideas?
