[asterisk-users] Local channel that runs a custom app... why immediate hangup?

[eric weaver]

I have an app which handles a Mitel's command port to change the MWI
lights.  It detects dial tone, plays some DTMF digits, listens for
dialtone-or-busy, does a manager event on what it finds, and returns.

Since the Mitel command port does not give answer supervision (looks like
it's ringing), and since I run this app via a AMI "originate" command, I set
up an extension in extensions.conf thus:

exten => MWISend,1,Answer(1000)   ; does more-or-less the same thing without
the delay
exten => MWISend,2,MWISend(${MWISEND_DIGITS})   ; the variable set in the
AMI call - this is tested & works.

The Originate goes like:

Channel:   Local/MWISend at default
Extension:  650nnnnnnn
Context:  direct_out   ; a context that dials SIP/${EXTEN}@metaswitch  which
is known to work
Priority: 1

What happens is the local channel goes immediately into Hangup with many
odd-looking messages about searching for the extension, when it has clearly
already been found and goes into a hangup(see trace below).

Anybody have a hint what's happening here and how to make the application
see the voice frames from the dial-out?
Thanks.

--- at this point the AMI application sees the hangup event and terminates
