Project Description: Requirement of a WebRTC based Chat system with backend as mysql database supporting multi domain architecture in a hosted environment. Should be able to work with existing mysql database already populated with user credentials from both Mysql User list or LDAP user list. Cross domain communication should not happen until approved from domain administrator. Presence capturing of all the users in the single domain should be a feature. geographic location capture from IP address resolution with location name along with presence. Audio, video and text chats should be functional. File sharing with the clients should be a function. Client screen sharing should be a function. The chat should be integrated with the existing web based emailing system and available as a tab on the existing system without disturbing the UI. There should be a tab in the web console to move it to a detailed and bigger tab if the need be. Option to include Conference calls/ Group chats on Audio and Video from a detailed tab window from web console. There are multiple domains in the environment . We should not allow a user of one domain to communicate with a user of another domain until the same is centrally approved to that domain by the domain administrator.
