Yep, see files below.

index.html displays a little form to enter the phone number.  It posts 
to place-call.php, which creates the appropriate call file.  In 
accordance with tips from the wiki, it creates the call-file first and 
then moves it into the spool folder, in order to avoid concurrency 
issues.  This file contains the following:

Channel: SIP/224
Callerid: <number entered>
MaxRetries: 1
RetryTime: 60
WaitTime: 30
Context: dial_auto
Extension: <number entered>
Priority: 1

This instructs asterisk to dial SIP/224 with caller-id <number entered>, 
and once answered, launches it into <number>@dial_auto:1, this of course 
then takes over and dials the number the caller entered.  This assures 
the person requesting the call that someone's going to be at the other 
end when the pick up.
