MWI not working

[kmccracken]

Thank you arcinsurance for your reply. I was actually able to solve the MWI problem myself, but your clue about the mailbox line is very relevant.

My steps for solving it:
I connected the T38G to an asterisk system that has a bunch of Polycoms & where I know the MWI lights were working properly (therefore, the system configs are all fine & the problem would have to be on the T38G). Well, I got it to work there using the above phone config & I was wondering what gives? on the system where it didn't work have something to do with it being hosted off-site? I then read more about the mailbox line and realized that that was where my problem was.

I'm using many different contexts, to keep some callers separate and I had left the context part off of the mailbox line (where it was working, they were using "default" as the context, which is what the mailbox line will use if you don't put a context). Once I changed it (to 111@mycompany)(and did a core restart), the MWI worked like a charm.
