[Asterisk-Users] passing through MWI info from SBC

Is there alternative access to voicemail? Like web access?

If there was then you can write a program to check the site every 5 or 10 
minutes maybe every 30, and parse out the message listing and then send MWI 
to the phones if there is a VM waiting.

Or

You could get one of those cheep 20 dollar devices and hook it up to the 
serial port on the asterisk box and then you can use sty to monitor the port 
for changes. Then send the message that way. I'd have to research it a 
little more but it very possible.

Just a thought :)
