[Asterisk-Users] Channel Status in AGI

[asterisk]

I am looking for a way to quickly and easily test for on-hook channels 
from within a C-language AGI app. CHANNEL STATUS works but is a bit 
clumsy. I don't want to rely on strcmp'ing the returned '200 result=-1' 
as the meaning of this might change in the future. I am trying to create 
an ACD using MySQL and want to test each channel before I Dial it. Any 
ideas?
