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

You can subscribe to events for everything, but ARI events are a subset
of what are available over AMI so you may not get what you want. Events
raised by applications for example would not be present. You can
subscribe to all channels by subscribing to "channel:" using the
/applications//subscription resource, and "bridge:" for all
bridges.

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

[Calum Power]

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

Re: [asterisk-users] Non-global variable that follows channel?

[Jonathan H]

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!

Re: [asterisk-users] Non-global variable that follows channel?

[Jonathan H]

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@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@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

There are a few problems with the way you are trying to use SHARED
here.
1)  Dial with the g option continues in the dialplan when the called channel
hangs up and you are accessing a SHARED variable on the called channel
while it is being destroyed.  Thus it may or may not still exist when you
attempt to access it.
2) You are using local channels.  Remember local channels always come
in pairs.  The local channel name you are using to reference the SHARED
variable is ambiguous.  Not only do you not know which half of a local
channel pair you will get, you may not even get one of the local channels
the Dial created for this call if you have more than one of these calls
happening in parallel.

Executing this CLI command:
CLI> originate local/s@svtest1 application echo

Your dialplan creates this channel chain when Local/s@svtest2 executes
the Answer:

Echo() -- Local/s@svtest1-;1 -- Local/s@svtest1-;2 --
Local/s@svtest2-0001;1 -- Local/s@svtest2-0001;2 -- Answer()

These problems can be avoided if we make a couple of changes.
1) Change which channel maintains the SHARED variables to the calling
channel.
2) Pass the calling channel name to the called channel using variable
inheritance.

[svtest1]
exten = s,1,NoOp()
same = n,Answer()
same = n,Set(__MY_CALLER=${CHANNEL(name)})
same = n,Dial(Local/s@svtest2,,g)
same = n,NoOp(Returned SHARED(sharedVar) = '${SHARED(sharedVar)'}
same = n,Hangup()

[svtest2]
exten = s,1,NoOp()
exten = n,Set(SHARED(sharedVar,MY_CALLER)="I have been set in svtest2 by
${CHANNEL(name)}")
exten = n,Answer()
exten = n,Hangup()

Re: [asterisk-users] Non-global variable that follows channel?

[Jonathan H]

Thanks, Max.

Yes, of course, you are right, and I am an idiot because I was tired
and putting underscores before the variable name when I read it back!
Then I forgot to post the followup email to say I had figured it out.

Now, this SHARED was not something I was aware of, but looked like an
ideal solution to passing variables BACK from to the parent channel.

However, it does not seem to be very reliable.

Code:

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

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


Output, 4 times from console, 4 times from a normal PJSIP dialin:

Of the 8 attempts. in only 3 instances the variable survives the
journey back to the parent channel, and seemingly randomly, too.
Am I using it incorrectly?

CLI> originate local/s@svtest1 application echo
 Answered channel:Local/s@svtest1-0027;2
 ***In channel:Local/s@svtest2-0028;2 sharedVar: "I have been set

Re: [asterisk-users] Touch tone stutter

[Max Grobecker]

Hi,

you could try switching the DTMF mode of the ATA's SIP peer (and also in the 
ATA itself) to INBAND transmission.
In this mode, the ATA doesn't need to recognise DTMF tones and your Asterisk 
can interpret it.
For this to work, the ATA needs to use a G.711 codec. Inband DTMF needs an 
uncompressed codec to work properly.

Another way is (if the ATA supports it) to switch DMTF mode to SIP INFO.
In this mode, DTMF is not interpreted out of the audio stream. For external 
peers which are not supporting this mode
Asterisk then generates the proper RTP messages or tones.

With SIP INFO mode I made my best results with all devices, sadly it's not very 
common used.

Re: [asterisk-users] Non-global variable that follows channel?

[Max Grobecker]

Hi,

is channel variable inheritance working for your setup?
Passing variables to other channels can normally simply be done by naming the 
variable with one or two prefixed undersorces
to make it available to the channel that is created from that one defining the 
variable.
But I have no idea if it's getting inherited to Gosub called from a Dial 
command...
 -> https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Application_Set

If that is not working for you, you might use the SHARED() variables which are 
kind of global accessible by the channel ID.
So you might call your Gosub with only the (unique) reference name of the 
variables you wish to pass and then call it from your Gosub.
