Well, think of your provider implementing an answering machine "in the network" for you. Whenever somone leaves a new message on your answering machine, the (subscribed) PJSIP client will get notified by the server and your application can turn on that red blinking "MWI" LED to *indicate* the new message to the user. When he gets home, he looks at his phone and knows instantly: there is a new *message waiting* for me. Further reading: http://www.ietf.org/rfc/rfc3842.txt Section 4 contains some examples, but since PJSIP already does all the heavy lifting (the headers), the only thing you need to do is parsing the MWI body like: Messages-Waiting: yes Message-Account: sip:alice at vmail.example.com Voice-Message: 4/8 (1/2) Sebastian.
