Visual Voicemail SMS show up in Chatty
This was discussed a bit in the Matrix room, but I think it's a good idea to put it here.
Modem Manager displays Visual Voicemail related SMS as a regular text, and as a result, it is displayed in Chatty, which may confuse users.
Long term, it probably makes sense for Modem manager to expose TIP-ID so Chatty can see it (and ignore it):

But I also wanted to see if it made sense to have some sort of dbus communication between Chatty and vvmd (maybe vmmd tells chatty to ignore those messages?).
