Summary:                    [patch] 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.

We use our own equipment and our own driver. The driver just sends E1 from
hardware to DAHDI base driver. We don't use drivers for wctdm24xxp or wctdm
drivers and etc.  Do we need to do something in our driver?

Voicemail is not used, but we didn't disable it. Is it possible to correct
this situation by changing .conf files?
