asterisk users - Mar 2011 - [1.4] Forcing Asterisk/Zaptel to wait until callee answers?

Hello

	I need to write a script that will dial a list of customers and play
a message.

I couldn't find a way to tell Asterisk/Zaptel to wait until the callee
has actually picked up the phone before proceeding with Playback():

===========;call made through Dial(): Doesn't proceed after off-hook/hangup
[internal]
exten => 8888,1,Dial(Zap/1/${IPPI})
exten => 8888,n,NoOp(We never get there)
exten => 8888,n,Hangup

===========
;call made through callfile: Doesn't wait for off-hook
[callbacktest]
exten => start,1,NoOp(DialStatus is ${DIALSTATUS})
exten => start,n,NoOp(${CHANNEL(state)})
exten => start,n,Playback(tt-monkeysintro)
exten => start,n,Wait(2)
exten => start,n,Hangup

===========
;tried this to force callfile to wait until off-hook
[callbacktest]
exten => start,1,Set(INDEX=0)

;Down, Rsrvd, OffHook, Dialing, Ring, Ringing, Up, Busy, Dialing
;Offhook, Pre-ring, Unknown

;Tried "Up", "OffHook", and "Rsrvd", to no avail
exten => start,n,While($["${CHANNEL(state)}" != "Up"
& ${INDEX} < 10])

exten => start,n,NoOp(Channel still ringing: ${CHANNEL(state)})
exten => start,n,Wait(1)
exten => start,n,Set(INDEX=$[${INDEX} + 1])

exten => start,n,EndWhile()
===========
If there are people who use an FXO to make outgoing calls to perform
this type of task, how do you get Asterisk/Zaptel to wait until the
remote phone is off-hook?

Thank you.

Having traversed this "rabbit-hole" the answer is that it depends on
your
carrier.  If they offer "call-supervision", asterisk can wait for
pickup on
the other side.  The resolution I came up with for my offering:

; this context is used by AMI to play a message
[delivery]
exten => s,1,Answer
exten => s,n,Gotoif($["${EXTEN}" > "SIP"]?start)
exten => s,n,Wait(9,m)
exten => s,n,Set(IVRTRY=0)
exten => s,n(start),NoOp(Background(welcome))
exten => s,n,Background(important)
exten => s,n,WaitExten(5,m)
exten => s,n,Set(IVRTRY=$[${IVRTRY} +1])
exten => s,n,Verbose(Try ${IVRTRY})
exten => s,n,Gotoif($["${IVRTRY}" <
"4"]?delivery|s|start)
exten => s,n,Goto(end-call|s|1)
exten => 1,1,ForkCDR(v,s(fullcmd=${Data}))
exten => 1,n,Background(${Data})
exten => 1,n,Background(repeatmsg)
exten => 1,n,WaitExten(3,m)
exten => 1,n,Goto(end-call|s|1)
exten => 2,1,Background(calllater)
exten => 2,n,ForkCDR(v,s(reject=${Data}))
exten => 2,n,Goto(end-call|s|1)
exten => 3,1,Goto(delivery|1|1)
exten => *,1,Goto(delivery|s|1)
exten => i,1,Goto(delivery|s|1)
exten => t,1,Goto(delivery|s|1)

If the call goes out over a SIP connection, we start immediately, otherwise
we play music for 9 seconds to give the line a chance to connect and pickup.
Then we play "important" and have the user press 1 to hear the message
or 2
to get a call later.

I was going through the script this afternoon, and have a couple of
questions:

1. Why use ">" instead of "=" to compare the extension
with "SIP"?

exten => s,n,Gotoif($["${EXTEN}" > "SIP"]?start)

2. According to www.voip-info.org/wiki/view/Asterisk+cmd+Wait, Wait
only takes one parameter, while WaitExten() can take "m", which plays
music on hold: Is the wiki out of date and you are using a more recent
version of Asterisk than the 1.4 I have?

exten => s,n,Wait(9,m)

Thank you.

#1 is "Lazy notation" to say ${EXTEN} starts with SIP (as opposed to
Local
or DAHDI)
#2 Might just be a typo on my part. I frequently switch usage between Wait()
and WaitExten().

Thanks for the clarification.

Then you probably want ${CHANNEL}, not ${EXTEN}.  ${EXTEN} is always
going to be "s", which is always greater than "SIP".

I said it was Lazy, and I did this back on 1.4.21 under Zaptel. The ${EXTEN}
was sufficient for my purposes, though looking back I see it is not
"syntactically" correct.
