 Posted: Thu Mar 10, 2016 5:25 am Post subject: [asterisk-users] Dialplan question: Variables in GoTo() ? |
 |
|
I can't seem to find a definitive answer on this, and I really don't want to
risk breaking a production server to find out; so I am going to try asking this
here, and maybe anyone else in the same situation searching the archives
sometime in future will find the answer I get.
Can you use variables in the target of a GoTo() statement?
What I am specifically thinking of is this;
[from_some_source]
exten => s,1,AGI(look_up_stuff.agi,${CALLERID(num)},${EXTEN})
; this AGI script sets variables: next_context, next_ext, next_step
exten => s,n,GoTo(${next_context},${next_ext},${next_step})
Will this work? Does Asterisk evaluate expressions like this, or does it
expect literals?

Yes. Here are a few examples from one of my dialplans:
; invalid template
[i](!)
exten = i,1, verbose(1,[${EXTEN}@${CONTEXT}])
exten = i,n, goto(${CONTEXT},s,1)
; look up (set) DNIS (DID) channel variables
exten = _x.,n, goto(lookup-dnis,${EXTEN},1)
; dispatch to selected application
exten = _[123456],n, goto(${PRODUCT-${EXTEN}-APPLICATION},s,1)
This particular dialplan uses the invalid template in around 30 contexts
and 'goto(${CONTEXT},s,1)' about 15 times. Note that the last example
'nests' the variable expansion -- a variable within a variable.

Thanks in advance,

It most certainly will work. It evaluates on use.
