I'd have to check my work computer to verify that, I didn't bother building it outside of workspace, as it was way too much hassle than I was interested in.

shodown wrote: » SRND This is a must read if you are dealing with call manager. It gives you the breakdown the features of the version you are running and countless best practices of how to design your system. Its not perfect, but I always reference it when doing a new design.Cisco Unified Communications System 9.0 SRND - Preface [Cisco Unified Communications Manager (CallManager)] - Cisco When you are using NTP. The stratum is into reference how accurate the clock is with the lower number being better. Depending on the app you are running it may require a lower version than another app. For example Unity Connection can usually get buy with a higher staturm number than call manager, but you need to check the SRND for your version to find the acceptable range. Regardless you will be making your router the master so it will have a 1 and the other devices will fall in behind.

It is extremely expensive to have such device and there are some security regulations that you will not provide this timesource to third parties in example. Stratum 1 means a computer which is synchronizing its clock each few seconds to Stratum 0. Stratum 2 is synchronizing to Stratum 1 sources and so on. In general - Stratum 3 is almost every host, which has a synchronized clock. One good NTP source is pool.ntp.org - publicly available Stratum 1 and Stratum 2 servers. I'm synchronizing my Lab environment with them.
