As it turns out I had such a script in my little store of doom. So just in case the Asterisk Users post doesn’t get archived here it is:


<pre>
<?
///////////////////////////////////////////////////
// This is a quick script that allows the external
// monitoring to check that all is ok.
//
// Gareth#NetworksAreMadeOfString.co.uk
///////////////////////////////////////////////////
$s = stream_socket_client('tcp://127.0.0.1:5038',$e,$es,5);
if (!$s)
{
die('<pre>Error: '.$es.'</pre>');
}
stream_set_timeout($s,2,0);
fwrite($s,"Action: Command\r\n");
fwrite($s,"Command: zap show status\r\n");
fwrite($s,"\r\n");
$Response="";
while(!strstr($Response,'END COMMAND'))
{
$Chunk = fread($s,512);
$Response .= $Chunk;
}
fclose($s);
if(stristr($Response,"OK") === FALSE)
{
print("Issue detected");
print("-----");
print($Response);
}
else
{
print("Zap Lines OK");
}
?>
</pre>


Pretty simple I think you’ll agree, hope it helps someone out who doesn’t feel up to installing Nagios just to make sure the outside line is working!

Yesterday someone enquired as to how this is acheived because there appears to be some confusion as to how it is done.

Now I make no assertions as to whether this is the best way to do it but it works.

Extensions.conf

[globals]
Office1=SIP/200
LivingRoom=SIP/201
ServerRoom=SIP/202
All=SIP/Office1&SIP/LivingRoom&SIP/ServerRoom


With that done you then simply add the ALL extension to the necessary context


[incoming]
exten => 01234,1,NoOp(Incoming call!)
exten => 01234,2,Ringing
exten => 01234,3,Wait(1)
exten => 01234,4,Dial(SIP/Office1,30)
exten => 01234,5,Dial(SIP/All,30)
exten => 01234,6,Playback(tt-weasels)
exten => 01234,7,Hangup


Whilst it is possible to utilise the Dial command in the following way I prefer utilising descriptive names and other variables.


exten => 01234,5,Dial(SIP/200&SIP/201&SIP/202,30)


If anyone reads this and knows of another way or considers this particular method to be evil then let me know.
