small custom crm w/ asterisk & auth.net

I need to upload .csv with headers for call center workers to call using asterisk based autodialer. implement a few calling dispositions, and reporting of user performance. call center users will set appointments to an admin calendar. Admin will assign appointments to sales users (will have their own dispositions and reporting) based on their calendar availability. sales user will have asterisk dialing and integration of [login to view URL] virtual terminal. once sale is complete, autogen email sent to customer with temporary login information. customer user will login, update profile, and schedule a time on calendar for admin to assign to another user. m
