Conference Call with Asterisk ConfBridge

I need someone to the project; *** Conference call using asterisk ConfBridge. Asterisk to be hosted on EC2. current certified version of asterisk 13 to be used. i.) there will be [login to view URL] ( must be responsive) This site will just be two pages. Page-1 is the login page for a prospective conference participant. Username/ password to be used ==> phoneNumber/<one-time-string-as-password>. This username and password are maintained in a DB (mysql). ii.) At this stage, asterisk does not know about username/password ... and will never know. We just want to use this for our records ii.) User is taken to Page-2 after login. Page-2 has the web based softphone already registered with asterisk on EC2. this will be our only extension that users will use to dial a conference room number in asterisk from their web-browsers. We do not need webphones that will crash since we expect many people to be calling with it. Page-2 also displays all logged-in users (or participants) iii.) Prospective Participant dial-in conference extension ...say "1234" to join conference. iv.) Conference room will have an Admin. v.) we are particular with documentation because we would want to replicate same project on a difference EC2 instance.
