[Asterisk-Users] hangup detection

[Sean Adams]

Okay, I'm an idiot. The tones are picked up just fine by asterisk with 
no changes.

It helps if you understand the syntax of zapata.conf. I thought 
busydetect=yes just had to be under the context line. I didn't realize 
how the "channels=" is actually the delimiter that includes the stuff 
above it (I had busydetect below that line).

I should add that I find the asterisk config files to be very whacky in 
general.
