Re: [asterisk-users] Forking AGI or GoSub

[John Runyon]

Glancing at the code, Asterisk appears to wait for the pipe between
Asterisk and the AGI to be closed before it considers it completed. So, the
problem is this pipe is duplicated into the child.

Try adding this after setsid:
fclose(STDIN);
fclose(STDOUT);
fclose(STDERR);
fopen('/dev/null', 'r'); // set fd/0
fopen('/dev/null', 'w'); // set fd/1
fopen('php://stdout', 'w'); // a hack to duplicate fd/1 to 2

In PHP something like:

exit;
}

// we are the child, detatch from terminal
$sid = posix_setsid();

Dovid,

I'm not much of a PHP person, but in perl, i check the process id that's

Re: [asterisk-users] Forking AGI or GoSub

[Michael Munger]

I am very much a PHP person. PHP doesn't really have an elegant way to handle 
forking / threading, which can make it non-trivial to implement and can be 
unreliable if the implementation is not exact. PHP must also be compiled to be 
thread safe in order to do this properly.

Granted, the last time I looked into this with PHP was under PHP 5.6, and tests 
at that time did not yield the results we wanted. We ultimately moved to Python 
when we needed multi-threading, which is extremely elegant and reliable for 
this application.

Re: [asterisk-users] Forking AGI or GoSub

[Michael Munger]

What’s the purpose of the URL? Does it assist operators who handle the 
emergency services call?

Off the top of my head, I am not sure you can fork an AGI call from asterisk. 
Seems it would defeat the purpose of AGI, which should handle the call flow 
when it has control of the call. Have you considered have the AGI write to a 
socket of a secondary application, which will then perform the web call from 
its own process?

Seems relatively simple to write the call information to a socket as it’s 
getting processed, and then the AGI will complete in milliseconds and the call 
can continue. The secondary application can then do the URL POST. (You can 
probably whip this up in python very easily).

Not sure this solve the delay issue, however. If the secondary application 
stops running, you’d have to see if / how the AGI fails. I think it would just 
fail and the dialplan would just continue. Would need testing so it fails 
gracefully.

In my case this is for emergency services. The AGI calls a web URL with the

I had a situation that required this functionality -- processing a credit
card could take a second or two and we didn't want 'dead air' for our user
experience.

I created a pthread to play 'Please hold on while we process your card and
get ready for a good time...' while the main program continued with the
card authorization.

Most of the time the auth completed before the audio finished so it
appeared to be instantaneous to the caller.

The only caveat is to not interact (stdin/stdout) with Asterisk until
'stream file' in the thread completed.

I think php uses pcntl_fork().

Re: [asterisk-users] Forking a call

[mickael ropars]

Hi Mike,

Fork will generated 2 CDRs, and will seperate CDRs

But seems that there is a trouble in 1.6 (1.4 was working fine)

For exemple : phone A (leg A) is called, I play some background sound and
before putting in relation with phone B (leg B) I do a ForkCDR()

in 1.4 billsec in the first CDRs whas the call time on leg A and in the
second CDR the time of call on leg B
in 1.6 billsec on the two CDRs is the call time on leg B

in my case it cause some trouble since I cannot not charge the introduction
message (background sound)

Is it a known Bug ? or may be it's not a bug?


regards

Mickael

  Hi,



 Using 1.6.2.13.



 I'd like to know how I can force Asterisk to fork a call.  To simplify
 things, Let's say I have an out context (for outbound calls) and an in (for
 inbound).  If person A wants to call person B, and both are on my servers, I
 don`t want to send the call out.  I want all this to happen internally on my
 server.



 The problem is if I use some condition to send calls in my out context back
 to my in context, some channel variables get mixed up, and (for example)
 when the calling part puts the called party on hold, the music on hold used
 is the called party's music.  I am sure there are some less benign problems
 that could come with that.



 Is ForkCDR() what I am looking for? Any things I gotta watch out for when
 using it?



 I basically would like Asterisk to treat this call as two separate calls,
 as if one was completely outbound and the second an independant inbound
 call.



 Mike

[asterisk-users] Forking

[hh174]

Hello all,

Probably a bad news for all...

The Undercompetent Olle E Johansson decided to leave the asterisk team
to create his own Voip server.
The server will be called Minisk (due probably to his poor competence in
Voip).
Following that, Digium decides to stop any development on Asterisk and
joined the Skype team to recreate a brand new paying licensed software.
Any development will be halted for asterisk

It seems that Mr Johansson has was poisoned by a fish in Brussels during
the last Fosdem.

We all hope qur Mr Johansson will quickly heal and return to the team of
asterisk.

Kind regards,

Olivier Taylor

[Moshe Brevda]

what kind of command do you want it to do in the background? The obvious
answer your question would probably be to use an agi script.

You can call an AGI script that will call another script. That last one would 
wait 10 seconds and write in the database. The following example works for me:


/var/lib/asterisk/agi-bin/agi-test.agi:

#!/bin/bash
nohup /root/helloworld.sh 1/dev/null 2/dev/null 
exit 0



/root/helloworld.sh:

#!/bin/bash

echo Hello world!  /root/helloworld.txt
exit 0

There isn't a fork, but there is a method built in that is rather similar to
the alarm(2) interface in the kernel, which is called Absolute Timeout.  The
method of using this is Set(TIMEOUT(absolute)=30), which sets a timer that
will fire in 30 seconds.  When that timer fires, any application that is
currently executing will terminate, and you will be redirected to the T
extension in the current context.  Note that you can also cancel this timer
by using setting the timeout to 0, i.e. Set(TIMEOUT(absolute)=0).

Also note that there can only be a single absolute timeout per channel (i.e.
setting a new timeout resets any timer currently in effect).

[asterisk-users] Forking using Openser And Asterisk

[Aadilkhan Maniyar]

Hi All,
 
I am stuck with an issue in the Openser+Asterisk Forking. 
 
In this solution we are using Openser as the Registrar. Hence it will
store all the contact bindings along with the q values for a given user,
say ua1. The current setup is such that the INVITEs are sent to Asterisk
by Openser and Asterisk sends out the INVITE.
 
Now if ua1 is registered with two different contacts having different q
values and i make a call from ua2 to ua1.
Openser will recieve the INVITE check for the multiple contacts of ua1
in the database. and send out an INVITE for the first contact. On
recieving a 486 busy it sends out an INVITE to the second contact. This
is where the problems lies.
 
Openser is sending Asterisk the second INVITE but none of the actions
specified in the Dialplan (extensions.conf) of Asterisk seem to be
executing on reciept of the second INVITE.
 
My extensions.conf looks like this:
exten = _.,1,NoOp(Incoming Call [EMAIL PROTECTED])
exten = _.,2,Dial(SIP/${EXTEN})
exten = _.,3,HangUp()
exten = h,4,HangUp()
 
 
This is the ouput at the asterisk cli:
 
-- Executing [EMAIL PROTECTED]:1] NoOp(SIP/ua2-0921a250, Incoming Call
[EMAIL PROTECTED]) in new stack
-- Executing [EMAIL PROTECTED]:2] Dial(SIP/ua2-0921a250, SIP/ua1) in new

[asterisk-users] forking from a dial plan?

Hi,

is it possible to fork from a dial plan?

meaning, is there a way to redirect to two different

without waiting for the first to finish?

if you mean dial both and give the call to the first that answers, just

this is one of the specific scenarios, I got many others,
(for the shortsighted, this can be used in any case you don't want to  
wait for a chain of steps to complete before triggering another)

e.g.

1./ a call goes on queue,
2./ no agents are logged in,
3./ then, an announcement is played,
4./ other options are played
5./ then, the call is transfered to the voice mail,
6./ manger gets a ring with a record,(no-one-is-logged-in-damn-it)

Steps 3 - 5 can take up to one to three minutes to complete,
while I want 6 to be triggered asap, not afterwards 5, nor before 3  
(thus inserting a delay)

I can do it from within an agi script, by forking it,
(i.e. returns to the dial plan execution, while continues to run itself)
but I wonder if anybody figured (or if there's an specific  
instruction for)
forking out of the dial plan,

Why wouldn't you put #6 as #3, and have it generate a .call file to make a
new phone call?

forking out of the dial plan,


Some commands, like Background, will allow execution to continue. So, it
obviously can be done, when needed. But most things that need to happen
should happen in order. If it's complicated enough to be done out of order,
then AGI is probably more appropriate anyway.
