I'm working to get our provisioning working with SNTP with our config files.  I have it sort of working but I have a few questions in UC   What's the difference between "TCP SNTP Server" and "SNTP Server"?  What set the "SNTP Server"?  I'm able to set the TCP SNTP Server with tcpIpApp.sntp.address but I'm not able to update the "SNTP Server" field.  


I'm also able to update "TCP Time Zone" but I'm missing where I set the "Time Zone" that's underneath that field in the web gui.

Hello John,

welcome to the Polycom Community.

The community's VoIP FAQ contains this post here:

Jan 28, 2013 Question: Time and Date flashing or unable to set time correctly

Resolution: Please check => here <=


Since UC Software 4.0.0 the Web Interface itself also shows the parameters within the Field Help section:




The above illustrates the SNTP Server parameter actually being device.sntp.serverName

Please remember that using device parameters you also must use the device.set="1" to enable this.


Have a look at
