We received word the 9800 series support will arrive in June. Preview release notes should arrive in the next week or so, but it will be the function as the 8800 series, not a feature rich as the Poly Edge, but still a good phone option.

6/9/2025 update from zoom phone release notes on cisco 9800 series desk phones:

Device management features New or enhanced features

Support for Cisco 9800 series IP phones

Zoom Phone supports the following devices. Account owners and admins can add these devices to the Zoom web portal as part of the provisioning process:

Cisco:

DP9841

DP9851

DP9861

DP9871

Additionally, Zoom Phone supports the Cisco Desk Phone 9800 Key Expansion Module (KEM), allowing users to extend the functionality of their desk phones with additional programmable buttons. These keys can be configured for a variety of functions, including line keys, speed dials, and other supported features, offering greater flexibility and efficiency for high-call-volume users.

Notes:

The Cisco 9800 series phone will show the BLF-related line key as the "speed dial" type on the phone UI.

Due to known Cisco limitations, the 9800 series does not support a primary line key when only one key is configured, and all line keys will appear labeled as "speed dial".

This morning, I was able to successfully provision a 9861 with Zoom and after the initial startup, it rebooted and updated to phoneOS 3.4.1. The calendar button was disabled, and the cloud icon went away, so it looks to be happy. Hopefully, there will be more support down the road for this device with the Action Button and some other configuration options.

Cisco documentation has not been updated to reflect the Zoom support from what I could see. I am not sure what provisioning options could be setup from a config file for the devices, so will wait on making any changes. We do not have many devices yet but looking to possibly deploy more of them.

Be nice if the calendar worked but I doubt it will ever. On the 8800's, the calendar integration only works with Cisco Webex Calling. That might be the case with the 9800's. Fingers crossed.

Agreed. Zoom sees the Poly Edge as the primary phones, but IMO the 9800 series are a better device in fit and finish. I am not expecting it to be 1:1 on features from Webex, but have some additional support by Zoom would be welcomed and not keep most things with the Poly Edge line.

Thanks for sharing. Yes, I got my 9861 working yesterday as well. I have some questions for you guys. I have tested a NEW Poly Voyager 4320 headset with dongle plugged into my PC (so Zoom Desktop App works with headset) and I paired the headset directly to the Cisco 9861 so I could use it on the phone. I can seamlessly switch back and forth - works great! What are most people doing for headsets? Is anyone using the USB-C port on bottom or USB-A on side to connect headsets? Is everyone going Bluetooth direct (no dongle) these days or what?

One thing to note about Cisco phones. Traditionally they come in two flavors. Enterprise firmware (Specific to CUCM) or MPP (Multiplatform Phone) firmware (aka 3rd Party Call Control, or 3PCC, firmware). If you buy a Cisco phone, make sure you buy the MPP (3PCC) version, otherwise it will not work with Zoom Phone.

hi @jaron

All Cisco 9800 series desk phones use Cisco PhoneOS. Assuming you have performed Add Device on Zoom Portal for the Cisco 9800 series desk phone, the desk phone will automatically Zero Touch Provision (ZTP).

I did not believe this would work. Previous Cisco desk phones such as Cisco 8800 series needed to be multiplatform to work with Zoom Phone.

To verify, I added a Cisco DP-9851 to my account including assigning the phone to a user. I then plugged the phone into my local area network. After a few minutes, the 9851 can up. I was able to make and receive calls.

Please see the Cisco documents below. “Depending on how your administrator configures your phone on the call control system, you might use one of the following methods to register your phone:

Method 1: No action is required during the phone registration. The registration is done automatically. …”

Zoom uses Method 1.

Did my response answer your question? If so, please don't forget to mark the reply as an accepted solution.

thanks, eliot

Ive read the posts but want to clarify. As it stands today, do the Poly E550 and Cisco 9861 support the same feature set? Are these some features that only the poly has?

Thanks
