Summary:                    Strange nasty sound (Because Asterisk tryes to
handle new voicemail, but there is no voicemails, voicemail isn't used)
Description: 
chan_dahdi.c: 8369
  res = has_voicemail(last);
  if (last->msgstate != res) {
  /* This channel has a new voicemail state,					*  initiate a thread to
send an MWI message */
  ...
  }
But in comments for msgstate:
/*! \brief -1 = unknown, 0 = no messages, 1 = new messages available */
int msgstate;
So, if res=0 and last->msgstate = -1 there is a new message! But it's not
true.


So, more logical to fix like:
  res = has_voicemail(last);
  if (last->msgstate != res && res > 0) {
  /* This channel has a new voicemail state,					* initiate a thread to
send an MWI message */
  ...
  }
In this case the strange sound doesn't appear.
