asterisk users - Nov 2016 - Non-global variable that follows channel?

Thanks, Richard - your code does indeed work reliably 100% of the
time, and thank you for that explanation.

I do think the docs at
https://wiki.asterisk.org/wiki/display/AST/Asterisk+14+Function_SHARED
could do with more clarification.

BTW, there were a couple of typos in your code, so for anyone who
wants to copy/paste, here's Richard's code WITH the curly braces  (
Set(SHARED(sharedVar,MY_CALLER) should be
Set(SHARED(sharedVar,${MY_CALLER}) )

[svtest1]
exten => s,1,Answer()
    same => n,Verbose(1,Answered channel:${CHANNEL})
    same => n,Set(__MY_CALLER=${CHANNEL(name)})
    same => n,Dial(Local/s at svtest2,,g)
    same => n,Verbose(1,***In channel:${CHANNEL}
sharedVar:${SHARED(sharedVar)})
    same => n,Hangup()

[svtest2]
exten => s,1,NoOp()
    same => n,Set(SHARED(sharedVar,${MY_CALLER})="I have been set in
svtest2 by ${CHANNEL(name)}")
    same => n,Verbose(1,***In channel:${CHANNEL} sharedVar:
${SHARED(sharedVar,Local/s at svtest2)})
    same => n,Answer()
    same => n,Hangup()

Thanks again.

(BTW, looking forward to the day when Asterisk gets some kind of
asynchronous dialplan application - all this "dialling a local
channel" is just to get via music on hold so there's not silence while
a long operation happening, as per
http://lists.digium.com/pipermail/asterisk-users/2016-November/290384.html
:) )

Have you looked into ARI [1]?  I think it would be a closer fit to what you
want
to do.

Thanks. I did a while ago, but I couldn't make it "fit" what I
wanted to do.

Maybe with my increase Asterisk knowledge now I'll take another look.
Thanks!
