<p><span style="font-family:"Calibri",sans-serif;color:black">This has less to do with UCCX and more to do with the lack of time precision in Windows SNTP / NTP compared to the needs of UCOS. Yes, I know, die hard Redmond boys and girls will say that ever since
Win2003 that isn't the case but sorry, it is. (read: <a href="https://technet.microsoft.com/en-us/library/cc773013%28v=ws.10%29.aspx">
https://technet.microsoft.com/en-us/library/cc773013%28v=ws.10%29.aspx</a>). In fact, on page 84 (PDF page) of the latest SRND (<a href="http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11.pdf">http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11.pdf</a>)
Windows NTP is a flat nono for Cisco UC period.<o:p></o:p></span></p>

<p><span style="font-family:"Calibri",sans-serif;color:black">IOS routers are great but here is how I like to roll (excuse the crudeness of the drawing, put it together this morning before coffee). I typically use Linux servers for NTP because they are so darn
useful for other utilitarian things ..... can't count how many times just having a Linux box on the network somewhere helped me out.<o:p></o:p></span></p>

valid scenario? I figure that since CCM is pretty much authoritative on everything for CCX as it is it wouldn’t be a problem?</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black"><o:p></o:p></span></p>
