Re: [asterisk-users] AGI Problem
Danny's suggestion of using System instead of AGI was correct, it was wrong of me to use AGI here as there is no communication. The same script does communicate with asterisk when executed with different options, so I had just kept the same line using different options at different places. Today I changed the AGI calls to System at places where there is no response back to asterisk. Kept everything the same, instead of AGI(script.php,var1,var2) made it System(/path/script.php var1 var2) and it worked without a problem. This way I have been able to fix the problem where this caused a deadlock requiring human intervention. The lines in the dialplan that continue to use the AGI call still experience the same problem as before. Today it happened 9 times out of 10486 executions, but these are not as fatal as before, so they can almost be ignored. Are you reading the AGI environment in the script? Yes How are you passing variables from Asterisk? As channel variables or as command line parameters? What is the dialplan statement that executes your script? Command line parameters, explained above. Can you post the script source? Yes but I really cannot see how the script could have a problem, it is around 2000 lines and since my problem has come to a more manageable level, I would rather not bug you with debugging the whole thing:) If you captured the AGI dialog from a call when your script failed and you feed the same values (including the AGI environment) into your script from a shell does it fail? Yes it runs just fine. It even runs fine at different times from within the asterisk using AGI when the same number calls or is called. So the only variable that is different between executions is time. On a Unix system level, a 4 means 'Interrupted system call' -- assuming this is what your '4' signifies. BTW, I'm a 1.2 Luddite and the AGI return value was meaningless back then. Running these on 1.8.5 I'll migrate this setup to a different environment, perhaps try at different asterisk and try the signal catching mentioned before and if I get any more data will update the list.

Re: [asterisk-users] AGI Problem
Thanks for the response. Although I had already gone thorough a lot of these types of QAs during my own problem solving, your suggestions did bring a couple that I had not. In no particular order... Earlier, you suspected receiving a signal was causing your problem. Instead of ignoring the signal, how setting up a handler and logging the reception? The program is written in a very top to bottom way (himm stateless? non-oo? not sure what to call it) and would be really hard for me to catch those and figure out where it happened and clean things up. So I have been reluctant to do this. But it is one of those tests that I'll eventually hit if I cannot solve the problem. How about 'agi set debug on'? I was doing extensive logging in my scripts and had turned on full logging for asterisk but I had not turned agi debuging on. I did and carefully inspected the output. And there is nothing out of ordinary between successful executions and unsuccessful ones. Whose AGI library did you use? If you 'rolled your own' maybe you are violating the protocol. Nobody gets it right the first time :) What does the AGI do? Can you execute it outside of Asterisk by feeding it the appropriate cruft via STDIN? I am using my own. Yes agreed, but this doesn't even interact with asterisk at all. Just receives a couple values and updates jobs, database accordingly. Does not return anything back to asterisk. Yes executes fine outside of asterisk and even executes fine within asterisk 99.9% of the time. Are there any characteristics common to the 48? Same ANI? Same DNIS?, Same path through your dialplan? I have not been able to find any difference. So returning 4 doesn't mean anything special. It is just the return code received from the AGI application that was forked. What about the fact that asterisk does not continue with the dialplan after receiving 4, is that expected behavior? I have not been able to find what would make a php cli application exit with 4 other than exit(4). php does not log anything when this happens, doesn't write anything to stderr (I specifically remained on the console I started * to see stderr). So this can only be a crash of some sort of php cli binary. What type of a crash would cause it to return 4? I will keep digging.

All you need to do is set a signal handler and call syslog() to log the occurrence in a 'safe' place and then exit().. If the signal is already causing your script to abort, you're not doing any cleanup or recovery anyway. All we want to establish is if you are actually receiving a signal.

Re: [asterisk-users] AGI Problem
How much time your AGI is taking? Check if it is completing its task and not
killed by asterisk. I guess we've 6~7 seconds before asterisk kills all call
channel and related tasks.

Asterisk logs the execution of the AGI and script completed messages within the

Re: [asterisk-users] AGI problem using mono (.Net)
Hi douglas,
I made an AGI script with curl in my dial-plan. Take a look:
[custom-login]
exten = s,1,Set(LOGINOK=0)
exten = s,2,Read(codigo|custom/codigo|4||3|3)
exten = s,3,Read(clave|custom/clave|4||3|3)
exten =
s,4,Set(LOGINOK=${CURL(http://URL/cgi-bin/login.pl?codigo=${codigo}clave=${clave})})
exten = s,5,Set(TRY=$[${TRY} + 1])
exten = s,6,GotoIf($[${TRY} 2]?custom-finish,s,1:)
exten = s,7,GotoIf($[${LOGINOK} = 0]?custom-login,s,4:)
exten = s,8,GotoIf($[${LOGINOK} = 1]?custom-ok,s,1:)
login.pl
--
#!/usr/bin/perl
use CGI qw/:standard/;
use strict;
my $codigo = (param('codigo') ne undef) ? param('codigo') : 0;
my $clave = (param('clave') ne undef) ? param('clave') : 0;
my $i = 0;
$i = ($codigo eq $clave) ? 1 : 0;
print Content-type: text/html\n\n;
print $i;

Now you can use asterisk+curl to send and receive data. If you are
working with .net you can make web services integration + asterisk +
curl
Have an nice day,

Re: [asterisk-users] AGI problem using mono (.Net)
An update here. Yesterday's problem has been solved (partly). After looking closer at the results of my perl script, as well as looking at the documentation, I realized that we were leaving the escape character argument off of the STREAM FILE command in the mono application. After appending to the STREAM FILE filename, we are now seeing asterisk attempt to play the file (both in the console and /var/log/asterisk/full log). New problem: == Although we see the following in our logs / asterisk console: [Feb 26 11:11:05] VERBOSE[9824] logger.c: -- Playing 'filename' (escape_digits=) (sample_offset 0) All that the caller hears is a very brief click. And then the dial plan continues. This is causing me to wonder whether asterisk halts playback of the file, if the AGI script that send the STREAM FILE command completes/returns. Talking to my developer, I asked him to create a loop after sending the STREAM FILE command and read from stdin until he gets a string that starts with 200. I'm supposing that asterisk would send this AFTER the audio file has successfully played out. But again, this is only a guess. Thanks so much for the responses you provided yesterday. I look forward to further information you can assist us with.

And then the dial plan continues. This is causing me to wonder whether asterisk halts playback of the file, if the AGI script that send the STREAM FILE command completes/returns. If your AGI is exiting before the sound file has finished and without reading the result from STDIN, you have violated the protocol. Talking to my developer, I asked him to create a loop after sending the STREAM FILE command and read from stdin until he gets a string that starts with 200. All it takes is a single line oriented read. This is pretty elemental to the protocol -- issue a request, read the result. Most (all?) AGI libraries wrap these two steps into a single function call so the library user never has the opportunity to do anything in between. I'm supposing that asterisk would send this AFTER the audio file has successfully played out. But again, this is only a guess. It makes sense that Asterisk sends the result when the request is finished, successful or not. A few more suggestions: ) Try to STREAM FILE demo-congrats. ) Verify that your sound file is playable (in the correct format for the codecs you have loaded) by using playback() in the dialplan. Apologies if it is too basic (but still I forget sometimes...) that the file name is specified without the file type and is relative to Asterisk's sound directory (usually /var/lib/asterisk/sounds/) if the file name does not start with a slash. The error message you showed above looks like STREAM FILE is finding the file. I'm guessing that you are still violating the protocol or that the file is not in an acceptable format for the codecs you have loaded. It appears that you did not use an existing AGI library. Why not?

STDERR only goes to the Asterisk console if you are running 1.4 or later and enable agi debug in the CLI. I seem to recall something about AGIs not working correctly (streamfile or DTMF read) if your AGI script does not process the input Asterisk sends it on STDIN when Asterisk starts the AGI.

Asterisk simply quickly executes the program and moves to the next step of the dial plan, as though it didn't receive any commands from the program. Maybe you need a new developer? (Just kidding...) The agi debug command may shed some light on the problem. I'm not a big fan of AGIs outputting to STDERR. I like to pepper my AGIs with syslog() statements to show the program state and variables. We know it is running, and outputting its results, because we have called it from within a bash script, and in doing so, I set the script to output stdout to a txt file for testing (like this /var/log/asterisk/querylog). When we do this, the file does end up with the first line showing STREAM FILE filename. You can configure Asterisk to log a whole bunch of cruft to syslog with the following statement in logger.conf: syslog.local0 = debug,dtmf,error,event,info,notice,verbose,warning I'll apologize in advance if the text below underestimates your AGI skills. The AGI interface (is that redundant?) can be summarized as: 1) Asterisk sends a bunch of cruft (the AGI environment variables) to your program's STDIN. 2) Your program sends a request to Asterisk via STDOUT. 3) Asterisk sends a result to your program via STDIN. 4) Your program does something else. 5) go to step 2. It's very simple, but not very forgiving. Let's imagine a simple AGI that reads the ANI as a channel variable, parses out the area code and sets it as a channel variable named NPA. Thus, you can simulate the AGI environment with a shell script. For an example, imagine the following script named test-my-agi.sh: # the standard AGI environment variables echo agi_accountcode: echo agi_callerid: 1234567890 echo agi_calleridname: sedwards echo agi_callingani2: 0 echo agi_callingpres: 0 echo agi_callingtns: 0 echo agi_callington: 0 echo agi_channel: SIP/201-09456478 echo agi_context: newline echo agi_dnid: * echo agi_enhanced: 0.0 echo agi_extension: * echo agi_language: en echo agi_priority: 1 echo agi_rdnis: unknown echo agi_request: block-ani echo agi_type: SIP echo agi_uniqueid: 1195070681.28 echo # result for AGI command GET VARIABLE ANI echo 200 result=1 (5551234567) # result for AGI command SET VARIABLE NPA echo 200 result=1 # (end of test-my-agi.sh) You can test your agi by executing: ./test-my-agi.sh | my-agi Since your AGI requires specific interaction with Asterisk to play the file this method will not allow you to fully test it, but it may help identify where you are violating the protocol. This technique can even be used in an actual debugger like gdb so you can step through your code line by line.

Hi,
I'm running the last CVS asterisk version (I was running an older version
before with the same problem) and I've a problem with agi scripts.
Commands
results are not always correct.
I've made a small agi test script that execute ChanIsAvail on an
inexistent
extension:
#!/usr/bin/perl
$|=1;
while(STDIN) {
chomp;
last unless length($_);
if (/^agi_(\w+)\:\s+(.*)$/) {
$AGI{$1} = $2;
}
}
# Check
print EXEC ChanIsAvail IAX/24\n;
$result = STDIN;
print VERBOSE \$result\ 0\n;
# Check
print EXEC ChanIsAvail IAX/24\n;
$result = STDIN;
print VERBOSE \$result\ 0\n;
# Check
print EXEC ChanIsAvail IAX/24\n;
$result = STDIN;
print VERBOSE \$result\ 0\n;
Result is :
-- Executing DeadAGI(SIP/200-60d2, b) in new stack

The first result is ok (-1) but not the second and the third.
Why do I get different results for the same command?

Re: [Asterisk-Users] AGI problem with library path
You can add your library path in the /etc/init.d/asterisk script and restart asterisk via service. or You also can 1/ add your library path in your /etc/ld.so.conf 2/ type ldconfig as root. 3/ restart asterisk via service Hi List, My AGI seems work well in asterisk -vvvc mode, other than that it doesn't work. Its seems to me, when I run asterisk as daemon (service asterisk start .. on fc4), it doesn't know about my library path. How can pass libray path to my AGI script or asterisk?

Re: [Asterisk-Users] agi problem
Hi Smadi. I have tested the script in my box and seems to be working
just fine. By the way, in any programming language, the way to get the
asterisk environment vars, and in general all the communication is
through STDIN, STDOUT and STDERR
try to give us more info so we can help you

self.env = {1:'moe',2:'joe'}
while 1:

self.env[key] = data
because when i replace that piece of code with my own hardcode variables
things work just fine.
Now my question is does anybody have a clue why this code is not
working? or alternatively how can i read the environment variables in
python?

Re: [Asterisk-Users] AGI problem (crash)
Hi, I have the same problem, Im also running RH 9. But Im using SIP only with Cisco ATAs. There are reports of asterisk not doing well with RedHat because of the new threads handling in RH kernel. Maybe compiling a fresh rpm from kernel.org will solve the problem. Testing my AGI script (writen in perl) I had a dial command (not background), and I could cause asterisk to crash when hanging up when inside the script. But now I moved the dial command to the extensions file (setting a variable inside the script to pass to the dial command in the extension file) and the problem went away. Maybe it is because its difficult to hang up exactly during the execution of the script that runs and exits really fast now that it is not doing the dial. I will try to compile a fresh kernel and see if the problem persists, and post my results here.
