My testing of 1.6.2.17 as well as the svn branch of 1.6.2 a few weeks
ago indicated that MWI was fairly broken. I managed to get it working
somewhat reasonably on Snom phones with a combination of subscribemwi=no
(despite the fact that the Snom phones subscribe for MWI!?),
pollmailboxes=yes and pollfreq=30 (despite the fact that we have nothing
but Asterisk touching the voicemail files).

In the testing, I managed to get Asterisk to flood the phones with tens
or maybe hundreds of MWI's by simply leaving one voice mail.

No, I have not had time to file bugs, we simply did a fall back to
1.6.0.28 + a lot of patches. It was not the most serious bug anyway; the
larger problem is that Asterisk deadlocks.
