Description:$res = $AGI->exec("DIAL $dialstr");
$dialstatus = $AGI->get_variable("DIALSTATUS");
printf(":::::%d::::%s::::\n",$dialstatus,$dialstatus);
$answeredtime = $AGI->get_variable("ANSWEREDTIME");
print "----$answeredtime---\n";

debug info:
AGI Tx >> 200 result=-1
AGI Rx << GET VARIABLE DIALSTATUS
AGI Tx >> 200 result=1 (ANSWER)     AGI GET!!
AGI Rx << :::::0::::::::            DEBUG ERROR!!

I have find the 0003725 ,he said It put the line "#!/usr/bin/php -q" on my AGI files, and Asterisk considered them as AGI commands.

but my agi : #!/usr/bin/perl

****** ADDITIONAL INFORMATION ******

$dialstatus = $AGI->get_variable("DIALSTATUS");
printf("::-%d-:::-%d-::::-%s-::::\n",$res,$dialstatus,$dialstatus);
$dialstatus = $AGI->get_variable("DIALSTATUS");

the problem is that asterisk runs the agi, and therefore is the reciever of stdout, which printf() writes to in this instance.   Did you add the printf()'s or are they in there already?  Basically they just need to be removed.

because I can not get perl agi source-code,so I use PHP agi.

like perl-astcc
$res = $agi->exec("DIAL SIP/123/5508|30|HL(17982600000:60000:30000)");
$dialstatus = $agi->get_variable("DIALSTATUS");
print("#######\n");
print("--".$dialstatus);
print "\n";
print("**********\n");
sleep(1);
$answeredtime = $agi->get_variable("ANSWEREDTIME");
print("#######\n");
print "--".$answeredtime;
print "\n";
print("*********\n");

it output:

AGI Tx >> 200 result=-1
AGI Rx << GET VARIABLE DIALSTATUS
AGI Tx >> 200 result=1 (ANSWER)
AGI Rx << #######
AGI Tx >> 510 Invalid or unknown command
AGI Rx << --200 result=-1
AGI Tx >> 510 Invalid or unknown command
AGI Rx << **********
AGI Tx >> 510 Invalid or unknown command
AGI Rx << GET VARIABLE ANSWEREDTIME
AGI Tx >> 200 result=1 (6)
AGI Rx << #######
AGI Tx >> 510 Invalid or unknown command
AGI Rx << --200 result=1 (ANSWER)
AGI Tx >> 510 Invalid or unknown command
AGI Rx << *********
AGI Tx >> 510 Invalid or unknown command
AGI Rx << HANGUP
AGI Tx >> 200 result=1

the phpagi.php
do
{
     $str =trim(fgets($this->in, 4096));
} while($str == '' && $count++ < 5);

I think it read in only one time,

I modify it :
do
{
$str =trim(fgets($this->in, 4096));
$ri=strstr($str,"result");
} while($ri ==false && $count++ < 5);

AGI Tx >> 200 result=-1
AGI Rx << GET VARIABLE DIALSTATUS
AGI Tx >> 200 result=1 (ANSWER)
AGI Rx << #######
AGI Tx >> 510 Invalid or unknown command
AGI Rx << --200 result=1 (ANSWER)
AGI Tx >> 510 Invalid or unknown command
AGI Rx << **********
AGI Tx >> 510 Invalid or unknown command
AGI Rx << GET VARIABLE ANSWEREDTIME
AGI Tx >> 200 result=1 (7)
AGI Rx << #######
AGI Tx >> 510 Invalid or unknown command
AGI Rx << --200 result=1 (7)
AGI Tx >> 510 Invalid or unknown command

it seem output ok,but it can not hangup

that had nothing to do with my question.  Did you add the printf()'s or were they there already?
By: yippee (yippee) 2005-11-23 23:33:37.000-0600

yes,I debug it and add the printf()'s
By: twisted (twisted) 2005-11-23 23:53:37.000-0600

remove the printf()'s.   these write to stdout, and when dealing with the AGI, asterisk is stdout and provides stdin to the application/script that is executed.  if you remove your debug statements, more than likely it will work properly.  if you want to give debug output, do something like VERBOSE, which will print to the cli.

oh,not add the printf to cause this error.I find this error and add printf debug it.

astcc can not add cdr,so I find when it run => $res = &trytrunk($trunk, $phoneno, $maxmins); and can not run into => elsif ($res eq "ANSWER") {

so I debug

$res = $AGI->exec("DIAL $dialstr");
$dialstatus = $AGI->get_variable("DIALSTATUS");

and find it do not output my want.

I do not think it about printf .

I debug it use php,and guess  $str =trim(fgets($this->in, 4096));

This is apparently a programming/coding issue, not a bug in Asterisk. Please ask for help on the asterisk-users mailing list to see if someone can help you to write your AGI script properly.
