[asterisk-dev] Developing VM App for Astrisk running on Linksys SPA400

[Steve Wofford]

Note sure where to find the examples:
	chan_sip.c
	MWI_NOTIFICATION 
	application/simple-message-summary

I found this: src\voice\asterisk\appsapp_voicemail.c, not sure though.

I have never done any Asterisk development... bear with me.

Maybe they use the method from RFC 3842
(Message Summary and MWI Event Package)
http://tools.ietf.org/html/rfc3842

For examples in Asterisk see chan_sip.c.
MWI_NOTIFICATION, application/simple-message-summary, ...
