Asterisk server is used through soft phone to make a call between two users. Asterisk Gateway Protocol (AGI) is the protocol used as an interface for telephony applications. This code ensures that we have open file handles for STDIN, STDOUT and STDERR, which will manage all communication between Asterisk and the script.
