CAFE : Sending large file(s) from remote client browser to a Conference using MSRP APIs

MSRP support in CAFE has been evolving since I last wrote about it. Among the many new things, I am going to cover one of its important capability i.e., ability to send large file(s) from a browser running on a remote machine to the SIP phones. Without such a support in CAFE/MSRP, it is very hard (if not impossible) to achieve such a functionality in a converged container. Figure 1. Sending large file from remote client browser to the SIP phones. In Figure 1, Alice, Bhavani and Bob are in a voice conference named conf1@example.com. Some other user running on a remote machine sends a large file from his browser to conf1@example.com using CAFE/MSRP.  (Note that the SIP phones of Alice, Bhavani and Bob are MSRP capable eg.., Mercuro, Blink.) CAFE/MSRP provides very simple APIs to do this. The end user need to write a simple web application and deploy it in CAFE container. The web application needs to contain following simple things: (a) HTML page for the client browser (test.html):   (b) HTTP Servlet to handle the browser request and send the file to the SIP phones using the simple CAFE/MSRP APIs:     (c) And off course a VoiceConferenceBean is required for handling the voice conference. This bean gets invoked when the user joins the voice conference (As I mentioned earlier, we are sending file to voice conference attendees, using (a) and (b)).   To try it yourself: The complete application is avail...
