Misha Vodsedalek commented on ASTERISK-20119:
---------------------------------------------

This fix corrects a problem with MWI only for phones that subscribe to MWI and process only subscription related messages (ignore unsolicited NOTIFY messages).

> 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.
