Problem

The date and time displayed on your 8x8 desk phone are wrong or flashing.

Cause

Most likely, at least one of the following is occurring on your phone or network:

  • The SNTP time server address is not properly set, either on the phone or the network device giving out DHCP (router or server).
  • DNS settings are not properly configured either on the phone or in the router or server.
Resolution

Setting SNTP on your phone will require you to access the phone's administrator menu or web interface (GUI), for which you will need your device's IP address and admin password.

To set SNTP via the phone's web GUI

  7. Allow the phone to reboot.

If the date and time continue to flash or show incorrectly

The SNTP may not be able to reach the designated time server. Instead of pool.ntp.org, try setting one of the following IP addresses:

  • 15.185.186.215
  • 204.2.134.163
  • 204.2.134.164
  • 209.114.111.1

Or, ping pool.ntp.org and use the reply address as the (S)NTP/Time Server address.


Still not working? Move on to setting a static IP on your phone and configuring DNS.

Note: We highly recommend consulting an IT or network professional when configuring advanced network settings. If able, the network administrator should always check the IP address, and assign and log any static IP to avoid conflicts in the future.

Setting a Static IP on your phone will require you to access the phone's administrator menu or web interface (GUI), for which you will need your device's current IP address, the intended static IP address (if different) and admin password.

If the date and time continue to flash or show incorrectly

The problem might lie in your router or server. Potentially, the issue might also originate with your Internet service provider. See Additional Troubleshooting.

If the previous steps have not resolved the issue, have your network administrator ensure that SNTP and DNS are properly set in your network's router or server.

  • Primary Timer Server: 0.pool.ntp.org
  • Secondary Time Server: 1.pool.ntp.org
  • Primary DNS: 8.8.8.8
  • Secondary DNS: 8.8.4.4
  • DNS Domain: google.com

If all local troubleshooting fails, contact your Internet service provider to inform them you are having an SNTP issue and your network devices are unable to resolve the correct time and date.
