I have a problem with DIAL.
The scenario is this:

1. Asterisk will dial a number in a call list
2. called party picks up the call and hears a prompt asking if they want to
pick up ( this is done through M(marco) option in DIAL)
3. if called party does not want to pick up, go to the next number (this is
done through SET MARCO_RESULT= CONTINUE)
4. if called party decides to take the call, make some conversion, then the
call is completed and hanged up by the called party.

For 4, when the called party hangs up, I want to hang up on the calling
party as well.

This works if I use the dialplan by not including the "g" option in DIAL.
However, when I do the DIAL in AGI, the calling party does not get hangup
automatically at (4). So, it continues to execute the next line in the AGI,
which is not what I want.

The problem is that the result I can when executing the DIAL command within
AGI does not tell me whether the call was picked up or not. So, I have no
way of knowing whether to continue executing the AGI program or to issue a
HAGNGUP explicitly.

Dear Tony,

Thank you very much for your suggestion.
The thing is that ${DIALSTATUS} returns ANSWER regardless of whether the
called party hangs up or not.
For instance, when called party is being asked by Asterisk whether he/she
wants to pick the call, ${DIALSTATUS} returns ANSWER.

In the case where the called party accepts to take the call and then hangs
up after finishing the conversion, I want to stop AGI from jumping to call
the next number. On the other hand, if the called party decides not to take
the call, I want to let AGI to jump to the next number.

It seems like ${DIALSTATUS} does not give me the info that I need.

Thank you very much. Is there any other ways you may think of?

Thanks,
Pete

When you have returned from the Dial command, check the DIALSTATUS channel
variable. If the call was picked up, ${DIALSTATUS} will contain ANSWER.

Ah, I see. It's not just whether the call was answered, but you want what
happens on the called channel to govern future behaviour on the calling
channel.

Thank you very much. Is there any other ways you may think of?

The only way I can think of to do that is by using the Asterisk database
as a communication mechanism, combined with channel variable inheritance.

Before calling Dial, generate a unique key. This can be based on ${UNIQUEID}
for example. Store this in a variable with inheritance to dependent
channels (invoked by adding a leading underscore): e.g.

Set(_KEY=${UNIQUEID})
or in AGI
SET VARIABLE _KEY "${UNIQUEID}"

Then write an entry to the Asterisk database with a suitable family, this key
and an arbitrary value:

Set(DB(dial/${KEY})=0)
or in AGI
SET VARIABLE DB(dial/${KEY}) "0"

In the answer macro, you should be able to read ${KEY} (due to inheritance),
and if the user accepts the call, you delete the database entry:

NoOp(${DB_DELETE(dial/${KEY})})

In the calling channel, on return from the Dial, you check to see if the entry
still exists. If it does, then either the call was not answered, or else it
was answered and not accepted. You can then either try another dial (using the
same DB entry) or give up and delete the entry at that point.

Deleting the entry in AGI would be (I think):

GET FULL VARIABLE DB_DELETE(dial/${KEY})

Or you could do GET VARIABLE if you substituted the value of ${KEY} yourself.

Hope this helps (and that it works!)
