Summary:                    MWI NOTIFY is not being sent to phones subscribed to
events
Description: 
Even though a phone is subscribed for mailbox events the MWI indicator is
not changing when messages are left or deleted.  The MWI indicator only
gets updated every 30 minutes.

Attached is a sip debug of a call made to device 9903 and a message is
left in voicemail.  No notification is sent to the SIP device.  The PBX
public IP has been replaced with the value PBXPUBLICIP, phone public IP is
PHONEPUBLICIP, and phone private IP is PHONEPRIVATEIP.  NAT is not the
issue since BLF works without a problem.

The output of sip show subscriptions is as follows:

PHONEPUBLICIP     9903             3c26702391f1-yo  --              
<none>         mwi             9903 at devic 003600

Here is the device sip.conf and the general options.  We're using FreePBX
to generate the files.  I'll have to run the test on our test system to get
your the console output because there are so many calls on the system where
this original capture was done the output is almost useless for analysis. 
Both systems experience the same issue (as do all our 1.6.2.7 installs). 
When observing the console output directly myself there was nothing other
than the dialplan execution that was shown.  I will capture it however.
