[asterisk-users] Asterisk outbound calling does not wait for answer before playback

Hello Asteriskers, :-)

We're trying to set up an outbound notification calling for system 
alerts with Asterisk 1.4.0.  We generate a call file in 
/var/spool/asterisk/outgoing and the outbound call is originated through 
Zap/1 (Sangoma A200D to a Canadian POTS line).  The problem is that 
Asterisk does not wait for the other side to answer before it starts 
playing the message.  So the person called answers the phone after the 
second or third ring and only hears the tail end of the message and the 
"goodbye".

Ideally, we want to deliver the message immediately after the person 
answers, or if an answering machine picks up, right after the "beep".

Any suggestions?

(1) The call file generator script (works ok):
#!/bin/sh

TMPFILE=`mktemp /tmp/tmp.XXXXXXX` || exit 1
echo "TMPFILE = $TMPFILE"

cat <<EOT > $TMPFILE
Channel: Zap/g1/phone_number_here
Callerid: SYSTEM
MaxRetries: 2
RetryTime: 60
WaitTime: 30
Context: dialout
Extension: s
Priority: 1
EOT

mv -v $TMPFILE /var/spool/asterisk/outgoing

(2) The dialout context in extensions.conf (problem - starts playback 
before call is answered)
[dialout]
exten => s,1,NoOp(Dialout)
exten => s,n,Set(TIMEOUT(digit)=5)
exten => s,n,Set(TIMEOUT(response)=8)
exten => s,n,Set(MACHINE=0)

exten => talk,3(human),Goto(dialout-human,s,1)

[dialout-machine]
exten => s,1,NoOp(Dialout to Ans Machine)
exten => s,n,Playback(/tmp/asterisk-recording)
exten => s,n,Wait(1)
; we'd like to do something to wait for the "beep" here...
exten => s,n,Playback(vm-goodbye)
exten => s,n,Hangup

[dialout-human]

[asterisk-users] Asterisk outbound calling does not wait for answer before playback

Had the same issue time ago, but Eric shed good light on it, have a look at:

[asterisk-users] Asterisk outbound calling does not wait for answer before playback

Although probably not what you want to hear, I don't think there is any way
that Asterisk will detect answering supervision on an analog POTS line (I
believe that there used to be an option with some Telcos to get a polarity
reversal upon answering, but I don't think that is possible any more.)  If
you were willing to make the calls using a VOIP provider like Voipjet you
would not have this problem, but that might not meet your needs for other
reasons.
