Zoom Phone Certified Hardware

Last Updated:

The table below provides the list of supported phone devices for Zoom Phone. You can also see a list of supported features. Before you add devices to Zoom Phone, see an overview of the provisioning process.

This article covers:

Prerequisites to using Zoom Phone Certified Hardware

  • Desk phones must support TLSv1.2 to work with Zoom Phone.
  • You must have the latest firmware version listed below for your device to work properly. Click the firmware version in the tables below to download it. Starting October 2021, the Firmware supported column states the release date of the firmware.
  • To see firewall rules for zero touch provisioning, refer to the firewall rules for Zoom Phone.

Encryption

Zoom Phone SIP signaling communications from devices/client to server and during phone provisioning sessions occur over TLS v1.2 with AES-256 bit encryption. Zoom Phone call media is transported and protected by SRTP with AES-128 or AES-256 bit encryption for devices.

Important: By default, AES-128 bit encryption is enabled for devices. Admins must upgrade devices to AES-256 bit encryption using the web portal. Learn more about Zoom Phone encryption.

AudioCodes

Notes:

  • Some models with certain revision numbers are not supported. Refer to the AudioCodes website for more information.
  • For the 450HD, Zoom Phone only supports the generic SIP version. If you have Skype for Business (SfB) firmware, contact AudioCodes support to convert it to generic SIP.

Grandstream

Due to the enhanced security requirement, the Zoom Phone provision server does not support any endpoints factory certificates with MD5 along with some other limitations. Hence there are older hardware versions of the listed Grandstream models that might not support Zoom Phone assisted provisioning.

The following Grandstream devices have been verified to support the required certificates and encryption for Zoom Phone service:

Notes:

Check the hardware version number of your Grandstream desk phone

  1. On the back of your device, identify the barcode on the label of the device.
  2. In the P/N number, identity the last 6 digits number.
    The first 3 digits of that number will be the hardware version number. For example if the P/N is 962-00113-15A001, then the 15A will be the hardware version and stands for V1.5.

Poly

Notes:

  • Provisioned Poly devices will automatically upgrade to the latest supported firmware version. Set up firmware update rules if you don't want Poly devices to automatically upgrade.
  • Zoom only works with Polycom devices that are running at least version 4.0.0 of the UCS firmware. In previous versions (Polycom SIP software 3.x or earlier), upgrading from the phone's web interface, registration, and provisioning will not work with Zoom. This restriction does not apply to OBi Analog Telephone Adapters (ATA).
  • Polycom VVX OBi edition phones are not supported. The only exception is the VVX D230, which has OBi firmware but is still supported by Zoom Phone.
  • VVX 250/350/450 come with two firmware versions depending on the hardware revision (Old or New). Please review the Poly Product Shipping Configuration Change Notice for more detailed information about new hardware revisions.

Note:

  • Provisioned Yealink devices will automatically upgrade to the latest supported firmware version. Set up firmware update rules if you don't want Yealink devices to automatically upgrade.
  • After the June 14, 2020 firmware upgrade, the following end-of-life (EOL) models are only allowed to use ZTP once: T29G, T41P, T42G, T46G, T48G, W56P.
  • If you need to re-provision an EOL model, you will be prompted to enter the last 5 digits of the device's serial number to start the provisioning process. You can also use assisted provisioning.

Notes (A):

  • These are Poly end-of-sale models. Zoom will be removing support for these models in the near future.
  • Currently, Poly end-of-sale models with a date of manufacture that is older than the date noted are unable to support Zoom's security requirements and cannot be used with Zoom Phone. The manufacturing date is usually identified by a sticker on the bottom of the phone.

Note (B): These models do not support SIP video.

Note (C): These are end-of-life models.

Analog gateways

Note for ATAs: 

  • Only these ATA devices support fax. See the following fax setup guides for more information:
  • 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.
  • 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
    • MP-118 - 6 channels from 8
    • MP-114 - 3 channels from 4
