[asterisk-users] Check if a variable is set

Discussion:

Hi

Is there any way to check if a variable is set in asterisk? I've had a
look around and can't find a purpose built function for it.

I'm going to be using it to see if an argument has been passed with a
macro or not (e.g. see if ${ARG3} is set or not)

Thanks in advance

Ish

If you want to check in Console then NOOP can be used .if in case of
function call you can check its length if there exists some thing

I'm basically trying to make an argument optional in a macro, I'm
starting to think it's not possible

If I do this in my macro
exten => s,2,ExecIf(EXISTS(${ARG3})=1 & ${ARG3}=1|<whatever I want to do>

I see this in the console
Executing [***@macro-extcall:2] ExecIf("SIP/PACK501-08222428", "EXISTS()=1
& =1|<whatever I want to do>

As I didn't pass a third argument.

Essentially, what I'm trying to do in php terms would be this
if(isset($var) && $var==1)

Mind posting the macro itself? I think we might need to store the
return value of isnull then test with execif.

Something like:

exten => s,1,ExecIf(${${ISNULL(${ARG3})} = 1]|Set,ARG3=1)

Should work from what I read on voip-info.org.

Actually just noticed a typo try:

exten => s,1,ExecIf($[${ISNULL(${ARG3})} = 1]|Set,ARG3=1)

Had { instead of [ in the ExecIf.

Grrr, none of it works, and the ExecIf's default position in the case of
confusion is to execute rather than to not

Hi

Here it is

[macro-extcall]
;Macro created by Ish to handle external national calls
exten => s,1,Set(CALLERID(all)=${ARG2})
exten => s,2,ExecIf(${ARG3}=1|Monitor|My monitor arguments)
exten => s,3,Dial(SIP/44${ARG1}@carrier,45)
exten => s,4,Hangup

Execution id Macro(extcall|Dialled Number|Caller CLI)

Now to enable monitoring for an outgoing line it would be

Macro(extcall|Dialled Number|Caller CLI|1)

But I have 79 of these in the system already with just the 2 arguments and we use realtime so they are all in a DB rather than text file so I'd rather not go through all the existing ones and change them to

Macro(extcall|Dialled Number|Caller CLI|0)

If I don't have to.

Also, I don't like getting bested by machines!

Ish

We have a winner!

Thanks Danny.

My excuse of not thinking of that myself is working wholly in realtime
and mysql where you have to use priorities apart from when I'm writing
Macros. Did I get away with that?

My first though is using the isnull function.
