asterisk users - Nov 2016 - GotoIf Double Pattern Match [SEC=UNCLASSIFIED]

Hi guys,

Sorry if this is a really basic question, but I'm fairly new to Asterisk and
am self-teaching so please go easy on me :)

Basically what I am trying to do is match 2 patterns in a conditional GotoIf.
The first condition is that the callerid(num) must end in '13'
The second condition is that the first two digits of callerid(num) must be one
of 66,77,88 or 99
eg. 9913 would match, but 9013 would not. 6613 would match, but 6612 would not.

What I have written come up with is below, but I just wanted to see if I was
going about this the right way, and that this expression would actually work...

exten => B,n,GotoIf($["${CALLERID(num):-2}" = "13"] &
$["${CALLERID(num):0:2}" = [5-9][5-9])?change_context)

Any advice/suggestions/flames welcome :)

Cheers
Calum

Hi Calum

I think you'll need another closing square-bracket at the end of the second
conditional test in your example, ie:  5-9]])?cha

I also think you may need to wrap that second conditional up in the REGEX
function, although there are much smarter people on-list who will likely come
back with a better suggestion!

Also, checking the second character of CID is the same as the first character
(otherwise you'd match 56, 69, 97 etc).

I'm thinking something like:

$[${REGEX("[5-9]" ${CALLERID(num):0:1})}] & $[${CALLERID(num):0:1}
= ${CALLERID(num):1:1}]

Hope this helps anyway :)

Pete
