Cisco headsets and Webex App calling endpoints
Verified 2026-09-25 · 60 sources · tier 2
Cisco documents two primary platforms for administering its headsets: Cisco Unified Communications Manager and Webex Control Hub 36. The supported headset portfolio covers devices integrated across the Webex App, Cisco multiplatform phones (MPP), and Cisco Desk Phone 9800 Series endpoints 36574010.
Supported models and call controls
The Webex App headset support list includes 8 Cisco headset families: the 320, 520, 530, and 560 Series, the 720 Series, the 730, the Bang & Olufsen Cisco 950, and the Bang & Olufsen Cisco 980 57. The Webex App also supports call control from selected third-party headsets from Jabra, EPOS, Poly (Plantronics), and Yealink 60. However, Jabra headsets currently do not work on Webex VDI for Dell ThinOS 35.
Bluetooth wireless models include the Cisco Headset 720 Series, Cisco Headset 730, Bang & Olufsen Cisco 950, and Bang & Olufsen Cisco 980, all of which can also connect through a Cisco USB adapter 25. The Bang & Olufsen Cisco 950 connects to the Webex App through Bluetooth or the USB HD Adapter; direct USB cable connections are not supported 7. For the Cisco Headset 720 Series, raising the microphone boom mutes the call, and unmuting is blocked while the boom remains raised 3. Button actions on the Cisco Headset 720 Series depend on the device variant 64:
| Variant | Answer call | End call | Reject call |
|---|---|---|---|
| Webex 6 | Press Webex button once | Hold Webex button 2 seconds | Press Webex button twice |
| Microsoft Teams 4 | Single press of the Teams button | Single press of the Teams button | Hold Teams button 1 second |
In the Webex desktop app, user-configurable headset settings are located under Settings > Accessories after selecting the headset model 59. For the Cisco Headset 320 and 530 Series, the Webex App compatibility guide lists hold and resume as available only when connected to Unified CM 58.
Multi-app behaviour
The multi-app feature routes headset button presses to a single calling application at a time rather than broadcasting them across every open application 45. This applies to Webex 41.8 or later and Jabber 14.1 or later 44. Multi-app control functions only over Bluetooth or USB cable connections with Webex and Jabber 46. Under multi-app control, answering an incoming call in a secondary application does not automatically place the active call on hold 48. Multi-app support requires specific minimum firmware versions across supported headset series 47:
- Cisco Headset 320 Series requires 2.4(1) or later 47.
- Cisco Headset 520 and 530 Series require 2.3(1) or later 47.
- Cisco Headset 560 Series requires 2.1(1) or later 47.
- Cisco Headset 730 requires 1-6-0-150 or later 47.
Control Hub administration and inventory
The Webex Control Hub headset inventory tracks individual Cisco headsets connected to the Webex App, Webex Meetings, and the Cisco Accessory Hub desktop app 31. Each inventory entry displays the headset model, serial number, firmware version, connection status, and connection duration 29. Administrators can generate an inventory report or delete single headsets and groups of headsets from the organization's inventory 3028. Managing headset details in Control Hub requires an administrator role with device management permissions 26.
Control Hub provides 2 firmware release channels: Stable (TAC-supported and containing tested releases) and Beta (not TAC-supported, providing software for early field trials) 3334. When a Cisco headset connects to the Webex App or to a Webex-authenticated Cisco Accessory Hub desktop app, the application verifies the headset model and firmware, prompting the user if an upgrade is available 21.
Configurations can be applied to individual headsets via All Configurations on the device page, or in bulk by selecting multiple headsets and choosing Edit > Device Configurations 27. For the Cisco Headset 560 Series, Control Hub provides parameters beyond the 320, 520, and 530 Series: Bandwidth (default Wide Band), Conference (default Enable), Bluetooth (default On), and Radio Range (default Medium range) 2. The Cisco Headset 560 Series Conference setting permits up to 3 guest headsets to pair with the base 21.
Cisco Accessory Hub desktop app
Cisco Accessory Hub configures settings, manages firmware updates for Cisco headsets, desk cameras, and USB adapters, and registers devices to Webex Control Hub 15. Beginning in version 2.2.0.162 (August 2024), connected headsets and cameras register to the signed-in user in Control Hub 16. Version 3.0.0.314 (January 2025) added pairing and history management for the Cisco Headset USB-C Adapter, and version 4.2.0.410 (January 2026) introduced an MSI installer package 1714.
To update a headset in the desktop app, users select Accessories, choose the headset, open Headset info, and select Start update, with the option to specify a local firmware file 20. Cisco advises against running the desktop and web versions of Accessory Hub simultaneously during an update to avoid upgrade issues 19.
USB adapters and wireless pairing
Cisco offers the USB HD Adapter and the USB-C Adapter for wireless headsets 5318. The Cisco Headset USB HD Adapter ships pre-paired with its headset, whereas standalone USB-C Adapters require manual pairing 53. Re-pairing the USB HD Adapter involves holding its Pair button for 4 seconds until the LED blinks blue 54. The USB-C Adapter is paired using Start Pair in the Accessory Hub application and stores up to 8 connection history records 5455. Firmware updates for Cisco wireless headsets are not supported through either the USB HD Adapter or the USB-C Adapter 18.
Hardware endpoint support
Cisco Unified Communications Manager
Unified CM administrators can remotely configure headset parameters, including Bluetooth state, audio bandwidth, and wireless power range 52. Deployment requires activating the Cisco Headset Service, installing headset COP files containing firmware and configuration data, creating user profiles, and assigning profiles to users 5049. For configuration templates to apply, end users must be associated with User Profiles and their endpoint MAC addresses must be designated as controlled devices 51.
Multiplatform phones (MPP)
Cisco states that Cisco headsets require no administrative intervention on multiplatform phones running the latest phone firmware; the headset downloads necessary software on initial connection 40. Multiplatform phones support headsets starting at specific firmware releases 373839:
- Cisco Headset 520 and 530 Series: Multiplatform Firmware Release 11.1.2 or later 37
- Cisco Headset 560 Series: Multiplatform Firmware Release 11.2.3 or later 38
- Cisco Headset 730: Multiplatform Firmware Release 11.3.5 or later 39
Upgrades are configured under Voice > Provisioning > Cisco Headset Firmware Upgrade as a single string containing the protocol (HTTP or TFTP), server address, and the headset XML file 42. Cisco states that the headset XML file contents should not be altered 41. An upgrade triggers when the headset USB adapter is connected and the XML version is newer than the headset software, taking approximately 10 minutes 43. Phone resets do not erase headset configurations 41.
Cisco Desk Phone 9800 Series
On the Cisco Desk Phone 9800 Series, the Cisco Headset 720 Series and 730 require headset firmware 1-12-0-154 or later and connect over Bluetooth, USB, or USB adapter 10. 720 Series firmware upgrades require a direct USB connection on both 9800 Series phones and the Webex App 511. When connected to a 9800 Series phone, the Bang & Olufsen Cisco 950 and 980 do not support hold and resume from the headset 12. Cisco Headset 530 Series units connected via RJ-9 lack call controls, which function only over USB 8. Remote configuration of the 560 Series on 9800 Series phones requires Unified CM 12.5(1)SU3 or later 9. To prevent overcurrent issues with Cisco Bluetooth headsets on the Cisco Desk Phone 9841, Cisco advises connecting through the USB dongle or ensuring the headset is fully charged prior to connection 13.
