# description:	Asterisk is an Open Source PBX and telephony development platform that \ \
#		can both replace a conventional PBX and act as a platform for \
#		developing custom telephony applications for delivering dynamic \
#		content over a telephone similarly to how one can deliver dynamic \
#		content through a web browser using CGI and a web server.
