Summary:                    MWI is not sent to a SIP phone upon registration,
but is after the mailbox is updated/checked
Description: 
chan_sip and app_voicemail are both configured to use realtime for
configuration; additionally, app_voicemail is configured to use ODBC for
message storage.

When a SIP phone registers, and the mailbox assigned to that SIP peer has
unread messages in it, the phone does *not* receive a MWI notification upon
registration. However, any action taken to cause app_voicemail to check the
status of the mailbox (leaving a message, deleting a message, calling in
just to hear how many messages are present) immediately sends a proper MWI
notification to the phone. In this configuration, the SIP phone is *not*
subscribing for MWI notification, it's relying on Asterisk's default 'push'
notification mechanism.

It would appear that the SIP phone registration, which results in an
internal subscription to the voicemail box, does not actually cause
app_voicemail to check the mailbox's status as it should.

  Ensure that realtime mailboxes properly report status on subscription.
  
  This patch modifies app_voicemail's response to mailbox status
subscriptions
  (via the internal event system) to ensure that a subscription triggers
an
  explicit poll of the mailbox, so the subscriber can get an immediate
cached
  event with that status. Previously, the cache was only populated with
the
  status of non-realtime mailboxes.
