You disable "Subscribe for MWI", yet it still gets voicemail waiting notifications because your account will re-subscribe to the server.
So you can extend the time of "Subscribe Period(Seconds)" in the webpage.
Enter web UI->Account->Advanced, change "Subscribe Period(Seconds)" time as you want, then the notification will not prompt frequenctly.

Is that how it should work though? We have Snom models throughout and a few Yealink and the Snom's have a setting that says whether to check voicemail for that account and function as I think they should. If I disable MWI on an account, that means, to me, that I don't want voicemail notifications at all on the account. It doesn't mean that I want them only on an account resubscribe. What is the best way to file this as a bug?
