Just from memory, this is how I would expect things to work in Asterisk
right now.

In 1.4, you can have multiple mailboxes specified - mailbox=1234,5678 at
foo.
Asterisk will not send separate NOTIFY messages for each mailbox.  It will
determine a combined mailbox state and send that.

In trunk, it will actually send the state of each mailbox in a separate
NOTIFY
message.  Also, FWIW, the code to do this is actually very invasive and
would
not be easily backported.

I'm running SVN-trunk-r82835 over here in a test environment and only a
single NOTIFY is generated, even with multiple mailbox entries.  The
single NOTIFY does not appear to use the mailbox name (54321 and/or
654321) in any part of the message.

Note the invalid To header in the NOTIFY.  I've opened
http://bugs.digium.com/view.php?id=10756 against it.  Perhaps this error
is causing the rest of the NOTIFY to peer processing to fail.

Norm
