	If you do an "agi set debug on" from the CLI and run your AGI you
should see something like this:

	As you can see agi_extension and agi_dnid should contain the number
that the user dialed.  Those are all the variables that are
automatically sent to the AGI script from Asterisk.  I do not know why
you are getting the channel instead of the extension, you could try
giving the extension as a parameter to the AGI script if you cannot get
that from the included request variable.
