# Date and Time are Wrong or Flashing on Poly IP Phones

## Symptom

Your Poly IP phone displays a flashing or incorrect date and time.

## Applies To

- Poly IP phones

## Resolution

### Check SNTP on Your Phone

For this process, you will first need your phone's **administrator password** and **IP address** (if working in the web interface). After you have that, continue to either set of steps below.

1. Press the **Menu/Home** button.
2. Select **Settings**.
3. Select **Advanced**.
4. Enter the **phone password**, then press **Enter**.
5. Select **Admin Settings**.
6. Select **Network Configuration**.
7. Scroll down to **SNTP** and ensure the address is set to **pool.ntp.org**. Press **OK** if the time server had to set.
8. Scroll down to *GMT Offset*. **Set to your local time zone**. Press **Select** if the GMT Offset had to be set.
9. Press **Back**.
10. Select **Save Config**.
11. Back all the way out to the main screen to view changes.

### Check SNTP in the Phone Web Interface (GUI)

1. Obtain your phone's IP address. On the phone, press **Menu/Settings** > **Status** > **Network** > **TCPIP Parameters**. Note the **IP address**.
2. From a computer on the same network as the phone, open a web browser and navigate to your phone's **IP address**.
3. Log in using the username ***admin*** and your phone's **password**.
4. From the top menu, click **Preferences** > **Date & Time**.
5. Under **Time Synchronization**, ensure **SNTP Server** is set to **pool.ntp.org**.
6. At the bottom of the page, click **Save**.
7. Allow the phone to reboot.

**If the Date and Time Continue to Flash** The SNTP may not be able to reach the designated time server. Instead of **pool.ntp.org**, try setting the below address

- ntp2.packet8.net
- Or the IP of the Local Domain Controller, if applicable.

Or ping **pool.ntp.org** and use the reply address as the SNTP address. Still not working? Move on to the next troubleshooting step for help with *setting a static IP on your phone and configuring DNS*.

### Set Static IP and DNS

> [!NOTE]
> ***Note****:*
> 
> *We highly recommend consulting an IT or network professional when configuring advanced network settings. If possible, 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:**

- Your phone's admin password.
- Your phone's current IP address.
- The intended static IP address (if different), network Subnet Mask, and IP Gateway.

#### Setting a Static IP and DNS Via the Phone's Web GUI

1. Obtain your phone's IP address. On the phone, press **Menu/Settings** > **Status** > **Network** > **TCPIP Parameters**. Note the **IP address**.
2. From a computer on the same network as the phone, open a web browser and navigate to your phone's **IP address**.
3. Log in using the username **admin** and your phone's **password**.
4. From the top menu, click **Settings** > **Network** > **Ethernet**.
5. Set **DHCP** to **Disable.**
6. Enter all of the following
  - **IP Address**
  - **Subnet Mask**
  - **IP Gateway**
7. Under **General**, ensure the following are entered:
  - DNS Server: **ISP DNS 1 (See** [Recommended DNS Servers for 8x8 Service](/support/docs/recommended-dns-servers-for-8x8-service) )
  - DNS Alternate Server: **ISP DNS 2**
8. At the bottom of the page, click **Save**.
9. Wait for the phone to reboot. If it does not reboot, verify the information, then manually power-cycle the phone (unplug it from the power source, wait a full minute, then plug it back in and let it power on).

**If the Date and Time Continue to Flash Incorrectly** The problem may lie in your router or server. Potentially, the issue may also originate with your ISP. You may also try modifying the Time Synch option in the phone setting via web GUI:

1. Navigate to phone **Preferences**.
2. Click on **Date & Time**.
3. Expand **Time Synchronization**.
4. For *Override DHCP’s SNTP Server*, set to **NO**.

See the *Network/ISP* section of this troubleshooting article.

### Network/ISP

If date and time problems persist through the previous steps, there may be an issue with the device delivering Internet and SNTP settings to the rest of your network. If you or your network or IT administrator are able, on your **DHCP device** (e.g., the router, server, etc.), check configuration, and set **SNTP** and open **DNS**.

- **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. If the time and date are only off by a matter of hours and are *not* flashing, you may simply need to set the extension time zone.

### Set Time Zone in Admin Console

If the time is *not* up to date, 8x8 account administrators can set the time zone for the extension in Admin Console. End users can edit the time zone for their own extension.

1. Log in to **Admin Console.**
2. Select **Users**.
3. Select the preferred **Time Zone**.
4. Select **Save**.

## Cause

Most likely, the SNTP time server address or DNS are not properly set, either in the phone or the network device giving out DHCP (router or server). The issue may also originate with your Internet service provider (ISP).
