Summary:                    [patch] VMWI not sent after every OnHook, only when
messages changes from None to Some, or Some to None
Description: 
In sig_analog.c
Function: analog_handle_event
 EVENT_ONHOOK doesn't force VMWI updates any more.

case ANALOG_EVENT_ONHOOK
      switch (p->sig) {
                case ANALOG_SIG_FXOLS:
                case ANALOG_SIG_FXOGS:
                case ANALOG_SIG_FXOKS:
needs                 p->msgstate = -1;  /* force VMWI update */   

As yet 'msgstate' hasn't been handled in the conversion to sig_analog

---------------------------------------------------------------------- 
I looked through the issue with the MWI only being sent when the number of
messages transitions from 0 to 1 and 1 to 0  (i.e. not sent when the number
of voicemails changes to/from non-zero numbers.)  

The has_voicemail function within chan_dahdi eventually calls into the
has_voicemail function in app_voicemail.c.  This function returns 1 if
there are 1 or more voicemails in the users mailbox which explains the
phenomena.  This behavior present in 1.4 so I am assuming that this is the
manner that it has always behaved.  (or has done so since commit 134223.)
