Zoom Phone Certified Hardware

Important: There is a known issue with provisioning the Yealink VP59 Video IP Phone. Customers should avoid provisioning this model until a fix is deployed in June. Add a firmware update rule to prevent this issue.

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.

Visit the Zoom Certified page for more information on certification and the full list of Zoom Certified Devices. For Zoom Phone Appliances, see our list of supported devices.

Notes:

• Starting October 2021, the Firmware supported column states the release date of the firmware.
• 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.
• To see firewall rules for zero touch provisioning, refer to the Poly or Yealink support site.

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

Note:

• 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.

Cisco

Notes:

• Only Cisco multi-platform (MPP) phones are supported by Zoom Phone. This is indicated by 3PCC, 3PC, or 3PW after the model number.
• Please carefully review Cisco's documentation for compatible models and firmware conversion from Enterprise to MPP to ensure that the devices are compatible with the required firmware and services.

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.

Model	Mutual TLS with AES-256 encryption	Call media (SRTP)	Firmware version supported
GRP2601/2601P	✔	AES-256	1.0.3.57 (6/19/2022)
GRP2602/2602P/2602W	✔	AES-256	1.0.3.57 (6/19/2022)
GRP2603/2603P	✔	AES-256	1.0.3.57 (6/19/2022)
GRP2604/2604P	✔	AES-256	1.0.3.57 (6/19/2022)

Notes:

• The P within the model name stands for PoE (Power over Ethernet) which does not require a power adaptor.
• Contact Grandstream directly if your device model is not listed in this table and failed the assisted provisioning process.
• See the Grandstream GRP260x Configuration Guide for more information

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.

Yealink

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.

Note (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.
