[asterisk-users] Polycom MWI's will not turn off

[Bruce Komito]

I have seen this with Polycoms, ZIP2s and occassionally with Linksys 941s,
but only intermittently.  Sometimes a powercycle will clear it and
sometimes not.  We've never figured out what's going on, but we think it
is something to do with NAT and the phones not exactly sticking to the
spec, but that's only a presumption.
