[asterisk-users] Passing parameter to Queue-called macro

Hi all

I need to pass a parameter in a thread-safe manner to the Queue pickup
macro. This is to know when (and who) picked up an incoming call to a queue
and log that to my back-office system with a CURL to a HTTP endpoint.

However, the Queue application does not appear to allow passing of
parameters to the called queue pickup macro.

E. g. non-working code is:

[queuetest]
timeout = 60
retry = 2
member=>SIP/testnum

[macro-verdianswer]
exten=>s,1,NoOp(Entering Verdi answer macro)
exten=>s,n,NoOp(Value: ${ARG1})
exten=>s,n,MacroExit

[incomingcontext]

exten=>tstqueue,1,NoOp(Incoming call for VerDi)
same=>n,Set(curlResult=${SHELL(/usr/src/verdi/bash/verdiIncGetUUID.sh)})
same=>n,Set(curlResultLength=${LEN(${curlResult})})
same=>n,NoOp(Curl result for incoming call UUID from VerDi: ${curlResult})
same=>n,Set(CDR(accountcode)=${curlResult})
same=>n,Set(curIncAccCode=${curlResult},g)
same=>n,Macro(VCRECORD,stefantestEXT${CALLERID(num)}ACC${CDR(accountcode)},$
{EXTEN})
same=>n,Queue(queuetest,trhc,,,60,,verdianswer(${curIncAccCode}))
same=>n,Hangup()

This results, when executed, in:

 [May  8 15:14:50] WARNING[20921]: app_macro.c:309 _macro_exec: No such
context 'macro-verdianswer(2018050815141huzzu4
' for macro 'verdianswer(2018050815141huzzu4

How can one pass a paramter into the macro called by the Asterisk queue
application on queue pickup?

Alternatively, how can a global variable or ASTDB entry be made thread safe
to do the same?

Thank you

Stefan

[asterisk-users] Passing parameter to Queue-called macro

Hi,

maybe I am overlooking something, but channel variables should be thread safe,
shouldn't they?

I am using the following (sorry, in ael):

macro dial-queue (number) {
	Set(_ORIG_UNIQUEID=${UNIQUEID});
	Queue(${number},rCt,,,${timeout},,set-dst-agent);
	..
}

// the "context macro-..." things is an ael-specific workaround to get
transfer working (macro sets context to app_queue_gosub_virtual_context)
context macro-set-dst-agent {
	s => {
		Noop(${ORIG_UNIQUEID});
		&add-current-call-agent(${ORIG_UNIQUEID},${MEMBERNAME});
	}
}

macro add-current-call-agent (id,num) {
	Set(ODBC_ADD_CURRENT_AGENT(${id},${num})=1);
	return;
}

[asterisk-users] Passing parameter to Queue-called macro

Hi Marie

Thanks!

I was just worried about thread safety if I had to use a global variable, e.
g. it might be set to a value by one call (since I'm using the same global
for every incoming call to transfer the accountcode gotten from my HTTP
endpoint to the same macro, and there can be several calls simultaneously
all inserting HTTP-sourced values at more or less the same instant) and then
another call is in such a state that it then reads this call's data - and
never reads its logical "own" data. The classic concurrently accessed
single
variable issue.

Anyway, I've managed to solve this by declaring a variable in the main
dialplan as inheritable and storing my back-office relevant GUID in there,
then referencing that variable without the pre-prended _ in the macro:

E. g.

[verdianswer]
exten=>s,n,NoOp(Lodging CDR accountcode: ${curIncAccCode} as an incoming
call from ${numbersource} with VerDi and answered by ${MEMBERINTERFACE}...)
exten=>s,n,MacroExit

[telkomin]
.
.
.
same=>n,Set(curlResult=${SHELL(/usr/src/verdi/bash/verdiIncGetUUID.sh)})
same=>n,Set(_curIncAccCode=${curlResult})
same=>n,Queue(stefantest,trhc,,,60,,verdianswer)

The above works just fine for doing what I want to do, e. g. pass a
parameter from an Asterisk dialplan context into a queue-triggered "agent
just answered in the queue" Asterisk macro.

Thanks for the reply!

Kind regards

Stefan
