Headset Management on Older Versions of Cisco Unified Communications Manager
If you have a version of Cisco Unified Communications Manager older than 12.5(1)SU1, you can remotely configure your Cisco headset settings for use with on-premises phones.
Remote headset configuration on Cisco Unified Communication Manager version 10.5(2), 11.0(1), 11.5(1), 12.0(1), and 12.5(1) requires you to download a file from the Cisco Software Download website, edit the file, and then upload the file on the Cisco Unified Communications Manager TFTP server. The file is a JavaScript Object Notification (JSON) file. The updated headset configuration is applied to the enterprise headsets over a 10 to 30-minute time frame to prevent a traffic backlog on the TFTP server.
Note |
You can manage and configure headsets through Cisco Unified Communications Manager Administration version 11.5(1)SU7. |
Note the following as you work with the JSON file:
-
The settings aren't applied if you are missing a bracket or brackets in the code. Use an online tool such as JSON Formatter and check the format.
-
Set the updatedTime setting to the current epoch time or the configuration is not applied. Alternatively, you can increase the updatedTime value by +1 to make it larger than the previous version.
-
Do not change the parameter name or the setting will not be applied.
For more information on the TFTP service, see the "Manage Device Firmware" chapter of the Administration Guide for Cisco Unified Communications Manager and IM and Presence Service.
Upgrade your phones to the latest firmware release before you apply the defaultheadsetconfig.json file. The following table describes the default settings you can adjust with the JSON file.
Parameter |
Range |
Default |
Notes |
---|---|---|---|
Speaker Volume |
0 – 15 |
7 |
Controls the level of sound in the headset. 0 is very low while 15 is loud. You can configure this setting differently depending on the office environment in which the headsets are deployed. |
Microphone Gain |
0 (Off) – 4 (High) |
2 |
Controls how loud the user sounds to other people on the call. 0 means users sound quiet while 4 means users sound much louder. You can configure this setting depending on how much ambient noise your deployed headsets encounter. |
Sidetone |
0 (Off) – 3 (High) |
1 |
Controls how much of a user's own voice they can hear through their headset. 0 turns off sidetone while 3 means users receive much more feedback from their headset microphones. |
Equalizer |
0 (Warmest) – 6 (Brightest) |
3 |
Controls the Equalizer, known on the phones as Tuning. A setting of 0 means that users hear more bass in their headsets, while a setting of 6 means that users hear more treble. |
Audio Bandwidth |
0 (Wide Band), 1 (Narrow Band) |
0 |
Controls DECT bandwidth. When you set the bandwidth to narrow, Standard Base and Multibase headsets are limited to the DECT codec G.726. Set the audio bandwidth to Narrow Band if your wireless headsets are used in a dense DECT environment. |
Bluetooth |
0 (On), 1 (Off) |
0 |
Controls the use of Bluetooth on Cisco Headset 561 and 562 with Multibase. The base forgets any devices that have paired with it when this parameter is changed. You can disable Bluetooth if your users are operating in an environment in which information security is at a premium. |
DECT Radio Range |
0 (autorange), 1 (short range), 2 (medium range) |
2 |
Controls DECT range. By default, the Standard Base and Multibase have a DECT range of over 330 feet (100 meters) in ideal conditions. If you configure the DECT radio range to short, the headset base consumes less power but users can't move as far from the base while on a call. |
Conference |
0 (Disable), 1 (Enable) |
1 |
Controls the use of the conferencing feature on the Cisco Headset 560 Series. Conferencing allows up to three guest headsets to pair with the same base at once. See Cisco Headset 500 Series User Guide for more information on conferencing. |
