Asterisk behind Kamailio & Voicemail MWI

Once again my workaholic nature didn't let me rest this Saturday and Sunday as I kept thinking about how can the MWI indications work with Asterisk as voicemail server behind a Kamailio server. Kamailio is the REGISTRAR of SIP users.

Since SIP users register on Kamailio, so Asterisk won't trigger a NOTIFY on it's voice-message recording.

There are many methods discussed on voip-info.org page. Among the other which weren't working or required patching I worked on manual SUBSCRIBE-NOTIFY triggering method by "Andreas Granig" which is openly discussed and shared on this mailing-list post in 2004. I haven't modified anything except the IP addresses for my servers.
