Now that we have simplified the environment, eliminated the AGI, and have 
some console output, we can see the problem.

Your Asterisk server is optimizing itself out of the path so IAX2/400 and 
IAX2/200 are talking directly to each other.

Packets are being exchanged directly between the two end points.

Your Asterisk server is no longer in control of the call and cannot hangup 
the call. If you wish to retain control, you need to disable transfer in 
iax.conf. Gee, who knew? It would be nice if Asterisk would warn you 
before it optimized itself out and there was a timer (absolute or S(x)) 
pending.

Please look at the dial command documentation. The second parameter is the 
timeout, the third is the options.
