I can't seem to comment directly to this Issue anymore, do you want me to create a new issue regarding the fact that MWI events don't trigger for "made-up" subscriptions unless there's an active dialog? (where asterisk has subscribed the phone despite that it didn't solicit an MWI subscription). (EDIT: Also, I'm using realtime peers but voicemail is being handled by a completely separate system)

> A peer MWI subscription gets cancelled when another SIP dialog (unrelated to the MWI subscription) gets destroyed. The MWI light on phones that rely only on subscription messages stops working (e.g., Nortel 1100 and 1200 series phones with SIP firmware).
> The problem is caused by an incorrect check if the dialog that is being destroyed is related to the MWI subscription.
> The same issue exists in Asterisk 1.6 as well as Asterisk 10.
