How to set the time server with the phone’s web interface
Find your phone’s IP address: on the phone, press the Menu key, then 2 (Status), 2 (Network), 1 (TCP/IP Parameters). The first line shows the IP address.
Start your PC browser (for example Internet Explorer) and put the address of the phone into the address field: http://192.168.1.100 or whatever it is.
The browser requests a user name and password. Use Polycom for the user name and 456 as the password.
A menu appears in the PC browser window. Select “General,” then “Time”
In the SNTP Server field put 0.us.pool.ntp.org. There are several pools – use the one appropriate for your region – see www.pool.ntp.org.
Set your time zone in the GMT Offset field. The value is in hours. Select from the drop-down list to set it. I am in US Central Time, which is GMT-6.
Click on the “Submit” button. The phone reboots.
A couple of minutes later the phone screen says Welcome, then with any luck shows the right date and time.
