I'm trying to get the value of a SIP header. However I couldn't find any documentation how to do that ( in PHP ). There don't seem to be examples either so I've took few guesses but obviously couldn't get it right. Below is the code that doesn't work.
x-numbertodial is the header I'm trying to access.
$headers = $currentCall->Headers;
$number = $headers->x-numbertodial;
say("Please wait while we transfer your call to $number");
So I think the question is actually where can I find the PHP documentation ? The examples are fine but is quite hard to browse through all of them just to find what you need.
