Zoom Phone Certified Hardware

• Note (B): These models do not support SIP video.
• Note (C): Yealink devices manufactured before 2019 are not compatible with Zoom Phone encryption and certificate security requirements. The device will fail Zoom Phone provisioning, even if it was added to the account manually or in bulk.
• Note (D): Only certain Yealink ZPA models are compatible with the Saudi Arabia data center.

Check the manufacturing date of a Yealink phone

Some models of Yealink devices manufactured before 2019 will not be compatible with Zoom. By following these steps, you can easily determine the manufacturing date of your Yealink phone.

1. Locate the serial number. You can find the serial number on the label, box, or within the user interface of the device.
2. Determine the manufacturing year:
   • For phones manufactured before or during 2021:
     1. Look at the 6th and 7th digits of the serial number. These two digits represent the last two digits of the manufacturing year.
     2. For example, for the serial number 312921805020XXXX, the 6th and 7th digits are 18, indicating the phone was manufactured in 2018.
   • For phones manufactured in 2021 or later:
     1. Look for a letter in the serial number. This letter represents the manufacturing year.
     2. For example, for the serial number 808040D04000XXXX, the letter D indicates the phone was manufactured in 2021.
        • D stands for 2021. E stands for 2022. F stands for 2023. G stands for 2024.

Analog gateways

Notes for ATAs:

• Only FXS ports can be used on ATAs.
• Only these ATA devices support fax. See the following fax setup guides for more information:
  • Poly OBi series
  • AudioCodes MP1XX series
  • AudioCodes MP1288, MP504/508(formally M500Li)
  • Grandstream HT8XX ATA series, GXW42XX ATA series
• ATA devices often support multiple ports. After performing assisted provisioning, you can assign multiple phone users to a single ATA device based on the port capacity available.

AudioCodes

Notes:

• For setup instructions, see the provisioning guide for AudioCodes MP series gateways.
• Some models with certain revision numbers are not supported. Refer to the AudioCodes website for more information.
• For assisting provisioning on the MP504/508 (formally M500Li) Analog Gateway, follow these instructions.
• When you enabled SRTP for these models, there is a reduction in the available channels. Only the following channels have SRTP enabled and are available for use:
  
  • MP-124 - 17 channels from 24
    Note: Follow this link to differentiate if you are using MP-124E or MP-124D
  • MP-118 - 6 channels from 8
  • MP-114 - 3 channels from 4
  • MP-1288:
    • The new firmware 7.40A.500 version will support both new and old hardware component blade. You can review the AudioCodes product notice #0491 component replacement for detailed information about new hardware revision.
  • (MP-1288, MP-112, and MP504/508 (formally M500Li) don't have a reduction in available channels)

Grandstream

Notes:

• Check the firmware and device certificate versions before proceeding to device provisioning.
• Check the ATA has the latest supported firmware version below, by following the upgrade process.
• Due to the enhanced security requirement, the Zoom Phone provision server requires the HT8xx to support Generation 2 (Gen 2) certificate using ECDSA + SHA 384. Verify your ATA unit has the updated Gen 2 device factory certificate installed.
• HT812/814/818 have 2 ethernet ports (WAN and LAN). For device provisioning under Zoom Phone web portal page, be sure to specify the MAC address value by using the LAN MAC address value (not the WAN MAC address) from the unit.
• When entering the provision/config server URL path under ADVANCE SETTINGS>Firmware Upgrade and Provisioning>Config Server Path, make sure to specify the URL WITHOUT the https:// on the front.

Upgrade an ATA Grandstream firmware

1. Sign in to the ATA web page.
2. Under the STATUS page, select Software Version, then Prog.
3. Download the firmware below if you have an older version.
4. Select the ADVANCE SETTINGS page, Upload Firmware, then Upload from local directory.
5. Follow the remaining steps to complete the upgrade process.

Verify Grandstream unit has the updated Gen 2 device factory certificate installed

1. Sign in to the device web page.
2. Under the STATUS page, select Individual Certificate Generation.
3. Verify the certificate name is GEN 2 (SHA-384 + ECDSA).
   • If it isn't the correct name, proceed to the Grandstream guide.
   • If it's the correct name, proceed to the Zoom Phone device provisioning.

Find an ATA Grandstream LAN MAC address value

1. Sign in to the ATA web page.
2. Select the STATUS page.
3. On the top of the page, find the LAN MAC (Device MAC) address value.
