[asterisk-app-dev] ARI Snoop Channel CPU Usage

[George Ladoff]

Gotcha. In most cases I do just need to snoop one direction.

Do you mean that the audiohook API would work in the way I was hoping in
those cases? Or do you mean that I may have some options of altering the
audiohook API but only if that were the case?
