Hi All,<br><br>After some research I decided to patch the ztdummy to provide the clock source for Asterisk.<br><br>Now, I'm wondering with a scenario where I have my card and another vendor card (e.g. Digium or Sangoma). How the clock will work in this situation? The true-zaptel-card (Digium or Sangoma) will "overwrite" my patched ztdummy and use its own clock? Is there a way to my clock have high priority in this case?
<br><br><br>Thanks in advance!<br><br><br>Paulo Garcia<br><br><br><br><br><br><br><br><br><br><br><div><span class="gmail_quote">On 6/11/07, <b class="gmail_sendername">Michael Cargile</b> <<a href="mailto:mcargile@explido.us">

<br>specify in the host operating system which virtual machine to pass spans<br>to. That way we can divide an eight port T1 card up amongst 4 Asterisk<br>instances. We plan on doing this in a similar fassion as Zaptel over
<br>Ethernet. Technically you could do this anyways by running an Asterisk<br>instance in the host and the VMs, then use ZOE between them, but that<br>basically defeats the idea of running Asteirsk in a VM which is to<br>
seperate instances from each other. Plus you would not get the timing<br>benifits from the physical zaptel device in the VMs.<br><br>So anyways I am of the opinion that if the device you are using to get<br>your timing is able to place a phone call to the PSTN in some fassion
<br>you should create your own zaptel driver. If not just create a patch to<br>ztdummy.<br><br>Michael Cargile<br>Explido Software USA Inc.<br><a href="http://www.explido.us">www.explido.us</a><br><br>_______________________________________________
