[Asterisk-Users] PHPAGI Swift Escape Digits

[Michael Stearne]

I am trying to use swift in PHP/AGI.

function swift($text, $escape_digits='', $frequency=8000, $voice=NULL,
$fnameIn='')

During swift speaking some text I want the caller to be able to press
1, 2 or 3 to do thing 1, thing 2 or thing 3.

How are these digit defines and then caught?

Thanks,
Michael
