This is my first attempt to write software of any sort. What I am trying to is
to use a .php page to query asterisk Manager and get the ExtensionState for
each particular extension. Then when it has the answer it outputs an XML file
for use as the directory on a Cisco 7960 phone. What I am thinking is that
when the user hits the directory button to veiw the directory that is at this
URL it will show the directory, but based on teh extenstion status it will show
whether that person in available or not. It should work pretty good as a blf,
you just have to request the directory again to get an updated status of
everyone that you are monitoring.
The problem I am having is that the only status that I can seem to get from
ExtensionState is -1. No matter what I do. I don't know why this is happening
and I have fiddled with the context how the extension is listed, however I
still jsut get -1 as a response.
It is my understanding that these are the possible status's:
-1 Channel is unavailable or does not exit
0 Channel is down and available
1 Channel is down, but reserved
2 Channel is off hook
3 Digits (or equivalent) have been dialed
4 Line is ringing
5 Remote end is ringing
6 Line is up
7 Line is busy
Here is my php code that logs into the manager api and then runs through an
array of my extensions and names and returns the XML file with name field
updated with the status:
I put some comments in with //'s so that you can get an idea as to what I was
thinking here. Most of this code I copied and pasted from php.net and other
places on asterisk lists.
<?php
header("Content-type: text/xml");
header("Connection: close");
header("Expires: -1");
print("<CiscoIPPhoneDirectory>\n");
//SET THE ARRAY WITH MY EXTENSIONS AND NAMES
$exten = array('Name1' => '201','Name2' => '202','Name3' => '203','Name4' =>
'204');
//RUN THROUGHT THE ARRAY TO GET THE STATUS OF EACH EXTENSION
foreach($exten as $name => $phone)
{
$fp = fsockopen("127.0.0.1", 5038, $errno, $errstr, 30); //OPEN THE CONNECTION
TO THE MANAGER
$out = "Action: Login\r\n";
$out .= "UserName: user\r\n";
$out .= "Secret: password\r\n\r\n";
fwrite($fp, $out);
$in = "Action: ExtensionState\r\n";
$in .= "Exten: $phone\r\n"; //HERE WHERE I AM ENTERING THE EXTENSION TO MONITOR
$in .= "Context: intern\r\n";
$in .= "ActionID: $phone\r\n\r\n"; //I JUST USED THE EXTENSION AS THE ACTION
ID, I DON'T KNOW TO USE IT ANYWAY
$in .= "Action: Logoff\r\n\r\n";
fwrite($fp,$in);
$fo = fgets($fp, 1024);//HERE IS WHERE I GET TEH ACTUAL RESPONSE FROM ASTERISK
$fq = strstr($fo, "Status:");//HERE IS WHERE I PARSE IT OUT THE "STATUS:" PART
$fr = substr($fq, 8, 9);//THESE ARE THE TWO DIGITS AFTER "STATUS:"
$fs = trim($fr);//HERE I TRIM OFF THE WHITE SPACE IF THE NUMBER IS NOT NEGATIVE
switch($fs)//HERE I RUN A SWITCH FUNCTION AND EACH CASE CORRESPONDES TO THE
VALUE FROM THE STATUS AND PRINTS THE XML ACCORDINGLY

Any input you may have would be fabulous. please forgive my php skills, it is
everything I have learned in about one day.
Thanks!
