[Asterisk-Users] FW: Exited non-zero

[Schochet, Wes]

I am working on this app to dial two external numbers. The second is dialed
after the first hangs up. I have simplified things down to:

exten => 3852,1,Dial(zap/g1/3964,10,g)
exten => 3852,2,Wait(2)
exten => 3852,3,Dial(zap/g1/7757,10,g)
exten => 3852,4,Hangup

Here is the debug:

    -- Accepting call from '0000000000' to '3852' on channel 0/23, span 1
    -- Executing Dial("Zap/23-1", "zap/g1/3964|10|g") in new stack
    -- Called g1/3964
    -- Zap/1-1 is ringing
    -- Zap/1-1 answered Zap/23-1
    -- Attempting native bridge of Zap/23-1 and Zap/1-1

Everything is OK here when someone picks up x3964.  Then when x3964 is hung
up, the first Dial command executes fine, returning -1 (as per the docs
since it is disconnected by the far end).  This causes a debug message of:

    -- Hungup 'Zap/1-1'
  == Spawn extension (from-internal, 3852, 1) exited non-zero on 'Zap/23-1'
    -- Hungup 'Zap/23-1'

And execution halts.  

I need to figure out either how to get the dial command to return 0 or get
the system to continue execution of the script despite the non-zero return.
Is there like an error handler / trap type routine that I can use in a
dialplan?  I am going to try and dig through the source code of the dial
command, but there has got to be a better way...

Has anyone dealt with this before?

Thanks in advance,

Wes

OK - this is great! However, I'm showing my lack of depth / newness here.  

Calls from internal SIP phones work perfectly.  Calls from external sources
(my PBX) fail.  Obviously, I have a dialplan / context problem, but I'd
appreciate a brief explanation and some direction from the group!

In extensions.conf, I have [from-pstn].  Under that section, I have included
[ext-postcall].  Then I have the following in an included file:

[ext-postcall]
exten => 3852,1,Answer
exten => 3852,2,Dial(zap/g1/8030,10,g)
exten => 3852,3,wait(5)
exten => 3852,4,Dial(zap/g1/8041,10,g)
exten => 3852,5,wait(5)
exten => 3852,6,NoOp(${DIALSTATUS})
exten => 3852,7,Hangup

The trunk group g1 is a T1 to my PBX and in the zapata.conf file I have the
entry 

context = from-pstn
..
..
Group = g1


Here is the trace from both an internal extension (205) and an external
extension.

There might be a simplier way.  a channel variable that holds the users
response, and a gotoif.  You should be able to pass 'g' to dial which
according to http://www.voip-info.org/wiki-Asterisk+cmd+Dial
g: When the called party hangs up, exit to execute more commands in the
current context.

So the agent just hangs up and the IVR will continue with the caller into
your survey if they so selected, if not it just hangs up.  That might be the
easiest way to do this.

You could even have the agent instructed based on that channel var
(depending on your CRM integration) to tell the caller that they will be
connected to the survey they opted to do so they dont forget and hangup too.
