I've had essentially no problems with my snom m3s. Someone from snom
has been in touch to confirm that they are now putting more effort into
the firmware for this phone. There are a few new features that I'd like
to see that are already in their plans.

Someone did report to me that they had difficulty getting MWI working
on the snoms. I've not been able to test this with Asterisk yet. Since
i rely on MWI from my desk phone (Polycom IP650) MWI on the cordless is
not setup, and I don't let calls to the cordless go to VM right now.
