Summary:                    Dial() with H drops inbound call
Description: 
One one particular system, we have a Perl AGI with this:

$agi->exec( 'Dial', "Local/$destination at enswitch-call/n,60,oH" );
$agi->verbose( 'Got here', 9 );

If the caller presses * to drop the outbound call, the inbound call to the
AGI is dropped too, and the 'Got here' is never printed.

This has been tested with 1.4.21.1, 1.4.26.2, and 1.6.1.6. The 1.4 tests
used "|" rather than "," as field separator in the dial string.

There are two Asterisk machines in this cluster and both are affected.
Numerous other systems running the same code are not affected.

Any ideas on how to debug this?

After speaking with jsmith on IRC, this is expected behaviour for that
option. Unfortunately I don't think the 'g' option will help you either
because it is the other channels dialplan execution that will happen.
