Zoom Phone Certified Hardware

This post was most recently updated on July 28th, 2022

Important:

Yealink VP59 Video IP Phones are known to have a known issue when provisioning them. This model should not be provisioned by customers until a fix is deployed in June, after which the problem will be solved. To prevent this issue from occurring, add a rule to prevent firmware updates from being performed.

Here is a list of the phone devices that are supported by Zoom Phone, which you can find in the table below. There is also a list of features that are supported that you can view. You might want to take a look at an overview of the provisioning process before adding devices to Zoom Phone.

If you would like to learn more about Zoom Certification and see a full list of the Zoom Certified Devices, please visit the Zoom Certified page. Our list of supported devices can be found on our Zoom Phone Appliances page.

Notes:

  • Starting with October 2021, we will be presenting the release date of the firmware in the Firmware supported column.
  • In order for Zoom Phone to work with desk phones, they must support TLSv1.2.
  • The device will not be able to function properly unless you have the latest firmware version listed below. In the tables below, you will find the firmware version that you need to download by clicking on it.
  • Please refer to the Poly or Yealink support sites if you want to see the firewall rules for zero touch provisioning.

Encryption

Communication between Zoom Phone devices/clients and the server as well as during the phone provisioning session takes place over TLS v1.2 with AES 256 bit encryption during Zoom Phone’s SIP signaling. SRTP is used to transport and protect Zoom Phone call media with AES-128 or AES-256 bit encryption depending on the device that is being used.

Important:

It is by default that devices are encrypted with AES-128 bits by default. AES-256 bit encryption must be upgraded by admins using the web portal in order for devices to be encrypted. Check out Zoom Phone’s encryption page for more information.

Desk phones

AudioCodes

Note:

  • Depending on the revision number of your model, some models are not supported. For more information, please visit the AudioCodes.ir website.
  • There is only a generic SIP version supported by Zoom Phone for the 450HD. You can convert your Skype for Business (SfB) firmware to generic SIP by contacting AudioCodes support.

Cisco

Notes:

  • Zoom Phone only supports Cisco multiplatform phones (MPP) that are Cisco MPP certified. As you can see by the model number, the 3PCC, 3PC, and 3PW are indicated respectively.
  • To ensure that the devices are compatible with the required firmware and services, please carefully review Cisco’s documentation regarding compatible models and firmware conversions from Enterprise to MPP in order to make sure the models you have purchased are compatible.

Grandstream

It is important to note that Zoom Phone provision server is not capable of supporting any endpoint factory certificates that have MD5 as well as some other limitations in order to keep up with the enhanced security requirement. Therefore, older hardware versions of Grandstream models listed are likely to be incompatible with Zoom Phone assisted provisioning, so older hardware versions of these models will not work.

Grandstream devices that support certificates and encryption for Zoom Phone services have been verified by the Grandstream team to support these certificates and encryption protocols.

Notes:

  • P within the model name indicates that the unit has Power over Ethernet (PoE), which allows it to function with or without a power adapter.
  • Those devices that were unable to be paired with Grandstream’s assisted provisioning process because they were not listed in this table should directly contact Grandstream directly.
  • There is more information about Grandstream GRP260x configuration in the Grandstream GRP260x Configuration Guide

Poly

Notes:

  • The latest firmware version will be automatically installed on Poly devices that have been provisioned. In order to prevent Poly devices from being automatically updated, you can set up firmware update rules.
  • As far as Zoom is concerned, only Polycom devices with firmware versions 4.0.0 or higher are capable of working with Zoom. The older versions of Polycom SIP software (Polycom SIP software 3.x or earlier) will not be compatible with Zoom in order to upgrade from the web interface, register, and provision the phone. The OBi Analog Telephone Adapter (ATA) is not subject to this restriction.
  • OBi Editions of the Polycom VVX are not supported by the software. It is important to note, however, that Zoom Phone still supports the VVX D230, which has the OBi firmware, but Zoom Phone does not support it.

Yealink

Note:

  • The latest supported firmware version will be automatically installed on all Yealink devices that have been provisioned. To prevent Yealink devices from automatically updating, set up firmware update rules.
  • T29G, T41P, T42G, T46G, T48G, W56P models that are end-of-life (EOL) will only be able to use ZTP once with the June 14, 2020 firmware upgrade.
  • A device after it has been discontinued will require you to enter the last 5 digits of its serial number to re-provision. Assistive provisioning is also an option.

Note (A):

  • This is an end-of-sale model from Poly. As of the near future, Zoom will cease to support these models as well.
  • In the current situation, models with an end of sale date that is older than the date noted on the product label cannot be used with Zoom Phone since they do not meet Zoom’s security requirements. Usually, the manufacturing date of a phone can be found on the bottom of the device, which is usually identified by a sticker.

Note (B):

There is no support for SIP video on these models.

Note (C):

This is a model that is at the end of its life cycle.

Notes:

  • In order to get setup instructions for AudioCodes MP series gateways, please refer to the provisioning guide.
  • It is not possible to support certain models with specific revision numbers. More information can be found on the AudioCodes website.
  • There is a reduction in available channels when you enable SRTP for these models. SRTP is only enabled on the following channels:
    • There are 17 channels instead of 24 on MP-124
    • There are six channels instead of eight on MP-118
    • There are now three channels instead of four on MP-114
    • Neither MP-1288 nor MP-112 have a reduction in channels (MP-1288 and MP-112 have no reduction in channels)
