asterisk users - Aug 2007 - AGI answering the channel even though I never asked it to

I am working on a call-back solution where the initiating call should  
never be answered.

I was doing this simply through the dial plan, sending a progress  
tone, and then dumping the channel, and firing off a DeadAGI which  
created a call file to make the callback.

Now I've tried extending this so that an AGI is fired first to check  
for things - like no inbound ANI - and play a DIFFERENT progress tone  
for that situation.  It appears that every since I've done that,  
Asterisk is answering the channel.  I don't have an Answer command in  
my dialplan or AGI.  Is this something that will automagically happen  
whether I want it to or not?  If so, I'm going to have to do some  
ugly dial plan scripting to make this work.

In case it matters, this is a PHP AGI.

Thanks,
Daryl

Hello Daryl,

See
http://www.asterisk.org/doxygen/1.4/res__agi_8c.html#c631d48f46d51d4b057

The AGI application will answer the channel if it isn't already
answered.

You probably need to do whatever you want to do in the dialplan, and
keep using DeadAGI.
