[asterisk-users] MWI working perfectly. Shouldn't it be broken??

[Karl Fife]

I see.  Thanks Russel.

And I now notice that if I explicitly tell my 962 the IP address of the
mail server, it will also subscribe.

Do I understand correctly that we are not talking about redundant MWI
status traffic here, we're ONLY talking about the notion that asterisk
ignores MWI subscription status and behaves as if it has 100% MWI
subscription.  That is unless "subscribemwi=yes" is in sip.conf.  Is
that an accurate summary?

And theoretically, if I had thousands of endpoints and I needed 100% mwi
subscription, there may be some theoretical efficiency to turning off
all MWI subscriptions in all of the endpoints.  Likewise if only 25% of
my 'thousands' of endpoints needed any MWI, there would be some
efficiency in setting "subscribemwi=yes", and explicitly subscribing
only those 25%.  Is that right?

Thanks again for clarifying!  I appreciate it!
