When Asterisk starts an AGI script, it feeds the channel variables to the script on standard input. The variable names are prefixed with "agi_" and are separated from their values by a colon and a space. Though the actual channel variables may be in the upper case, the names passed to an AGI script are all lower case. Global variables are not passed to the AGI script in this manner.
* agi_request - The filename of your script
* agi_channel - The originating channel (your phone)
