One thing to watch for here is RX gain if busydetect does not seem to be 
working after trying all the combinations.

I had a 2 x X101P setup which busydetected perfectly - TX and RX gains 
were at the default levels.

The X101Ps were replaced by a TDM card with 4 x FXO modules and with no 
config changes, busydetect stopped working. After incrementing in 1dB 
steps, an RX gain of 3.0 brought back reliable busydetect.

I look forward to Rich Adamsons forthcoming writeup on setting up the 
gain distribution in an Asterisk system, to get everything working 
optimally.
