<div>Thanks for the input.</div>
<div> </div>
<div>I am going to check this once I get access to system again
tonight.</div>
<div> </div>
<div>But I thought the timing source dahdi_dummy is only good for
features like MeetMe or conference rooms? or am I wrong and it has an
effect on any type of calls and checking voice messages?</div>

<div>Thanks<br>

<div class="gmail_quote">Asterisk needs a good timing source, in
the case when you don't have a physical card providing it, it relies on
kernel ticks or the RTC (or HPET). Because of the nature of virtual
machines they don't always get access to the processor when they want
and therefore their timing can get skewed and can be bad for real-time
applications.</div>
<div class="gmail_quote"><br>
</div>
<div class="gmail_quote">There are some patches/work-arounds that
you can do. You might want to google 'asterisk in a virtual machine' or
'asterisk timing virutal machine', or anything along those lines.</div>
<div class="gmail_quote"><br>
</div>
<div class="gmail_quote">I think I remember in some of the recent
dahdi or asterisk release notes that they changed some settings to be
more virtual machine friendly. So maybe make sure you are running
the latest versions?</div>

What in the world? Bruce, that is a measure of accuracy of your timing
source. I believe that is the issue. What is this running on?<br>
