<DIV>Interesting. We get the occassionaly complaint about MWI not being sent and
don't usually look into it unless there have been quite a few complaints. We are
using Unity so I would guess it would try a few times, again, IF it detects a
failure. What version of CallManager introduced these confirmation tones? We're
at v3.3(4)sr2.</DIV>
<DIV> </DIV>
<DIV>I guess I want to make sure I'm not wrong in telling people that one off
MWI misses are not something that we can totally eliminate. I guess I'll talk to
my SE about that and get a yes/no from him and go forward.</DIV>
<DIV> </DIV>
<DIV>Now, that being said, I did take a look in the event logs and aside from
some other errors, we are getting some of these:</DIV>
