if the implementation is not exact. PHP must also be compiled to be thread safe in order to do this properly.<o:p></o:p></span></p>

Is there a reason you can't fork in the AGI and just return to the dialplan in the parent?<o:p></o:p></p>

I'm not much of a PHP person, but in perl, i check the process id that's returned from fork() and exit if it's 1 (parent) and keep processing if it's the child (greater than 1).<br>
<br>
I think php uses pcntl_fork().<br>
<br>
Is that how you're doing it?<o:p></o:p></p>
