I believe I made one mistake in my example, I don't use a call to Queue
in my local channel without a partner channel (the customer). I'll
revisit this later today when I have some time, I'll be glad to help you
if I can recall the right solution :)

Re: [asterisk-users] Variable inheritance with dialplan command Originate
Hi Sherwood,
Thanks for helping me with this. The reply was indeed to you - I didn't think
you could use Dial on a channel that had been hung up, so I have learnt
something. However I'm still struggling with it I'm afraid. I've tried using
Dial and I'm finding that when the original channel is hung up it all seems to
stop working.
In the hope you might help me more, I've run your example as it is (translated
into .conf cos that's what we use here - feel free to reply in ael) so I can
show you the output. I'm finding it hangs just before the call to Queue. I know
Queue(2) works because when I dial 400 it works as expected.

exten => 400,1,Queue(2) ; control

exten => h,1,NoOp(The reference number is still here! ${referencenum})

I'm still not following why you think Dial is a bad idea. You're already
using a Local channel, which causes dialplan code to be executed upon
the start of the Local channel. Maybe you were replying to someone
else's post but hit reply on mine?
Your stated example in your email is pretty much EXACTLY what I'm
already accomplishing using Dial, Local Channels, and Variable
inheritance. Were it not for a Non-Disclosure Agreement that does not
allow me to share the specific code, I could show it to you and then
maybe you'd see what I'm trying to say.
Let's try a quickie example of what you're saying (I'm going to use AEL
this time, because typing same= > over and over drives me nuts)
context inbound {
// punter calls in
_X. => {
// code for recording the message and database junk
// code returns a reference number to the caller
Set(__referencenum=foo); // this is the inherited variable
Hangup(); }
h => {
Noop(The reference number is still here! ${referencenum})
// Here is where we trigger the queue call to the staff
Dial(Local/123@staffcalls) ;
} }
context staffcalls {
123 => {
Noop(reference number is STILL here ${referencenum});
// do your database lookup based on ${referencenum} here
Queue(staff) ; //obviously not a representation of your actual
queue request
} }
the above example accomplishes what you're talking about, without
inheritance problems, and is working in a callcenter without issues.

Re: [asterisk-users] Variable inheritance with dialplan command Originate
Hi,
The reason I think Dial isn't appropriate is not to do with the database call.
Here's the wider context of the application I'm putting together:
Punter calls in, leaves a message, gets a reference number, hangs up. System
then initiates call to a queue of on-call staff and when one answers it plays
them the ref and the punter's message.
The Originate bit is when, after the punter's hung up, the system initiates an
outgoing call.
I've worked around the inheritance problem by using the reference number as the
extension, which being the primary key then allows me to retrieve the rest of
the data from the DB again once over the Originate hump.
Passing it all in the extension is an idea, but would not suit this case since
there is a lot of data and as the application develops the nature of the data
may change.

Still not sure why you guys need this...Here's my example
[firstleg]
exten => 200,1,Set(__myvar=foo) ; Don't forget you don't want quotes!)
exten => 200,n,Dial(Local/123@test_orig)
[test_orig] exten => 123,1,Noop(${myvar})
same => n,Set(dbtest=${ODBC_TESTQUERY(myvar)})

Re: [asterisk-users] Variable inheritance with dialplan command Originate
Another option is to pass the information in the extension. At times I have an
extension like
_[s][o][m][e]-[e][x][a][m][p][l][e].
And call it like some-example:info1:info2 and use cut to extract the info1 and
info2 values. Not real pretty but as this is computer generated calls it gets
the job done.

Thanks. That's as I thought (feared). Dial is not an option in this case but I
have come up with a workaround involving using a reference number as the
extension and then doing a database call. Not pretty but it works!

I believe that it's expected behavior because you're not creating a
"child" channel, you're originating a different set. Try using Dial
instead of Originate, and you'll get the inheritance behavior you
expected.

I believe that it's expected behavior because you're not creating a
"child" channel, you're originating a different set. Try using Dial
instead of Originate, and you'll get the inheritance behavior you expected.

[asterisk-users] Variable inheritance with dialplan command Originate
Hi,
I would have thought that when spawning a channel using the Originate()
dialplan command, variables prefixed with two underscores would be preserved.
However this does not work in the following case.
Dialplan code:
[intern]
exten => 200,1,Set(__myvar="foo")
exten => 200,n,Originate(Local/123@test_orig,exten,dummy)
[test_orig]
exten => 123,1,NoOp(${myvar})
exten => 123,n,Hangup()
[dummy]
/end dialplan code.
Console output:
-- Executing [200@intern:1] Set("SIP/200-0018", "__myvar="foo"") in new
stack
-- Executing [200@intern:2] Originate("SIP/200-0018",
"Local/123@test_orig,exten,dummy") in new stack
-- Executing [123@test_orig:1] NoOp("Local/123@test_orig-cbab;2", "") in
new stack
-- Executing [123@test_orig:2] Hangup("Local/123@test_orig-cbab;2", "") in
new stack
/end console output.
This is in Asterisk 1.8.3.
Is this expected behaviour or a bug, or am I just confused? I would appreciate
your thoughts on the matter.
Thank you,
Naomi
