System overview

• The Wireless headset system consists of three main products. Clave Base, Clave DECT Headset(s) (refer to 11. Appendix A for different models) and Clave DECT Dongle.
• The high-end headsets support DECT and BT technology to establish connection with other devices. They are used with the Clave Base and desk phone / PC / laptop/ mobile phones. The selected microphone is balanced together with the headset filters to reduce the background noise to provide an ultimate understandable and clear speech. On the other hand, the receivers are balanced to the receiver housing and cushion, so the headset will provide the user an excellent stereo experience.
• The figure below (Fig.1) illustrates the high-level description of the system. It provides the basic understanding of the environment in which the device needs to interact. Both communication possibilities of the Clave are presented in the drawing below and further defined inthe following sections.

Soft client support

The Clave Base provides support for various soft clients and thus, it can be used with both PC Windows and MacOS. This means that, the base combined with one of the Clave Headsets, supports the audio and USB API of the applications, such as:

• Microsoft Teams
• Customer client support implemented in PC tool
• Respectively, if the headset is used in standalone mode over a Bluetooth™ connection, the audio of the same applications (and more) will be supported. In addition to this, the devices can also be used as generic USB headsets for general audio.

Handover to VoIP multicell systems

• The Clave Headset and Clave Base can be integrated together into VoIP multicell and dual cell systems. The headset base will register on behalf of itself and the headset. The two registrations are independent but will be linked logically as one unit on the VoIP system.
• The purpose of this integration is to hand over the user’s calls to the VoIP system for the user to be flexible in terms of location (Fig.2).

Clave DECT Dongle

• The Clave Headset can be used with the Clave DECT Dongle, which will serve as a base station. This is convenient for users who want to use the headset remotely, for example in home office or on the road where it is not possible to bring the base station (Fig.3). The dongle is supported by both Windows and MacOS.

• Clave DECT also offers desk phone support (Fig.4).
• NOTE : United Headsets will provide USB API. The customer is responsible for implementing it on relevant phones.

• It is also possible to connect a Desk phone to an existing UH DECT system using the Clave DECT Dongle (Fig.5)
• NOTE: UH will provide USB API. The customer is responsible for implementing it on relevant phones.

Clave wireless DECT headset overview

• The Clave series are wireless DECT + Bluetooth™ headsets. As mentioned before, the headset connects to the DECT base, which act as a charger for the headset, via the DECT wireless technology. It can also connect via Bluetooth™ to supported devices, such as mobile phones and Bluetooth™ compatible desk phones.
• A Busy-light indicator on the headband is used to indicate that the user is busy. The headset also features Environmental Noise Cancellation (ENC) to suppress unwanted environmental noise for the microphone input and Active Noise Cancellation (ANC) to suppress the noise towards the user. The headset offers DSP assisted echo cancelling. The length of the headband is adjustable to suit the head-shape of different users and the tilting angle of the boom can be adjusted to fit the position of the mouth of different people.
• The DECT base/charger connects to the PC/laptop. It can access Microsoft Teams and a defined range of soft call clients from external vendors, as well as a defined range of desk phones via EHS interface. Call control can be managed via the base, attached desk phones, soft call clients on the PC or via the buttons on the left earcup of the headset. A conferencing feature allows up to 4 headsets to connect to the same base – users may be added / removed from the conferencing call on the fly.
• The primary application of the Clave is within call centers and office environments allowing the user to access the internet/VoIP calls and music playback via the PC/BT.

Type of Clave Headsets

• The headset auto-configures the DECT setup when connecting to the base, thus no country specific variants exist. As mentioned earlier, the Clave series covers 3 different headsets: (For more detailed features overview, refer to 11. Appendix A)

• To reset your dongle, press the button for 15 seconds or until all 3 LED (red, blue, green) turn on and then off. Then release the button and your device will proceed to reset its settings.

How to connect headset and base station

• The following steps serve as a guideline for the process of registering the Clave Headsets to the Clave Base. Registration mode is enabled by inserting the headset into the base cradle (Fig.15). The headset can be registered as both primary and secondary. When the headset is locked as secondary on another Clave Base or on an Clave DECT dongle, the user may return the headset to use its primary state by inserting the headset into the cradle of the primary base.
• Step 1 : Insert the headset into the base cradle.
• Step 2 :The headset identifies itself to the base.
• Step 3  : The base decides if the headset can register.

a. If the headset is allowed to register it plays back the “Registering” voice prompt once

1. The headset starts the “Registration, in progress” LED pattern.
2. The base displays a visible notification that cradle registration is initiated.
3. The headset plays back the “Registration succeeded” voice prompt once.
4. The headset displays the “Registration, success” LED pattern.
5. The base displays a visible notification that cradle registration succeeded.

b. If the headset is not allowed to register it plays back the “Registration failed” voice prompt once

1. The headset displays the “Registration, failure” LED pattern.
2. The base displays a visible notification that cradle registration failed.

Bluetooth™ registration

• The headset is registered to a Bluetooth™ device by holding the BT button for 2 seconds (Fig.16). This will enable pairing mode for the headset which then allows it to be discovered by other Bluetooth™ devices. The Clave can store up to 4 paired BT devices’ information and remain connected to 2 of them at the same time. In case of reaching the limit and pairing a new device after the 4 existing ones, the oldest device information will be overwritten by the new agent.

Major mobile platforms are supported, such as iOS and Android.

• Example of when there are multiple choices available is shown in the picture below.

• The units in the Settings Menu available are explained in detail in the following sections.

General

station.
Power mode| Normal| User can choose power mode. There are 3 options available:

Normal, Eco and Super Wideband

Time format| 24 Hour (HH:MM)| The time format can be set AM/PM, 24Hour(H:MM) or 24

Hour (HH:MM)

Secondary auto deregister|

On

| Can be on or off. When active and secondary headset is present in a conference call, the base will automatically deregister the secondary headset as soon as the conference

call has ended.

Power level

|

3

| Allows the user to set power level of the base. Can be se to adaptive or between values from 1(maximum power) to 6(minimum power).

NOTE: If the user is in an area with a lot of interference user can set the power level to 1 (max power) but that will contribute to the noise. The adaptive setting lets the base to adaptively choose the power level, but that will consume more energy. In an area with no other DECT devices present and/or other sources of interference using power level 6 (min

power) will save energy.

• The settings that this menu allows to configure are shown in the table below.

• This menu allows the user to configure the audio prompts that announce different events in the headset. The options in it are shown on the screenshot and described in more detail in the table below.

Registrations

• This menu allows the user to register/deregister a headset to the Clave Base. For more details on the registration process see 7. How to connect headset and base.

Adjust time

• Allows the user to adjust the time shown on Idle screen. There are 2 options to choose from: user can either Sync with Setup Tool or adjust time manually when unmarking the “SetupTool Sync” in the little checkbox. In that case an hour and minutes count appear in the bottom part of the screen and with the help of the Scroll Wheel user can navigate through and adjust the time. When scrolling down to edit either hour or minutes, user can choose the unit it wants to change by pressing on the Scroll Wheel Key. Arrows up and down will appear over and under the number and with the help of the Scroll Wheel user can change the value and press the Scroll Wheel Key again to confirm its choice after.

VoIP System

• From this menu item user can register the base to a VoIP system. Refer to 13. Register devices on UH VoIP system for more detail on VoIP registration.

Reset User Setting

• This menu item allows the user to clear all configurations to their initial values. When chosen the user can either confirm and reset all user settings or with the help of the Scroll Wheel Key – cancel. If there is a headset registered to the base, it will send the command further to the headset and reset all user settings for the headset as well.

Factory Reset

• Allows the user to perform factory reset and return the base to its initial state and clear the cache memory. If there is a headset registered to the base it will send the command further to the headset and perform factory reset for it too.
• NOTE : Reset user settings returns all configurations to their initial state. That is also what happens when we perform Factory reset, but Factory reset will delete all current registrations as well.

Call activity on base

• To have call activity on the base, a master headset must be registered and locked to the base. If the master headset loses connection during call activity, all the calls will be put on hold until connection is restored. If the link fails to restore in a couple of seconds, all calls  will be terminated.

Incoming call

• The base will notify the user with visible and audible indication whether an incoming call is from EHS or USB line (Fig.25). If both lines are in idle state and an incoming call is received to one of the lines, the base rings and displays the call. However, if there are two simultaneous incoming calls from two different lines, the active control is made by the first incoming call (the first that came is served first). The second incoming call cannot be accepted by the base until the first incoming call has been answered or ended, or the line is swapped manually by the user. This means that in case of having one of the lines occupied (in active call), the new incoming call will be displayed as waiting in a queue.

Active call

• When a call is active, the base displays the active call, and the audio path is connected between the far-end party and Clave Headset (Fig.26). It is not possible to have more than one active call on a single line at the same time.

On-hold call

• When a call is put on-hold, the base displays a hold call status and the audio path is disconnected between the far-end party and the Clave Headset (Fig.27). It is not possible to set EHS active call on-hold by the base.

Multiple calls

• There is more than one call existing in a single line (Fig.28).
• NOTE : EHS and DHSG lines do not support multiple call. That is because there is only one available path for the audio track. If we are using for example DHSG line with a desk phone and there are multiple calls on the desk phone, user has to toggle/control those via the desk phone interface. For more details on the EHS and DHSG connections refer to 10.2 EHS interface and 15. Appendix C: EHS and DHSG API.

Multiple line

• There is more than one call existing on different lines (Fig.29).

Active & Inactive line

• When a line is active, the base displays it in a green-colored field and enables the audio path to be connected via that line (Figure 23). It is not possible to have more than one active line at the same time. When a line is inactive, the base displays it in a grey-colored field and disconnects the audio path via that line. It is not possible to have manual call control of the base when the line is inactive.

Call termination

• All calls will be terminated when the master headset loses link or is placed on the cradle (Fig.24). That is in case, if it is not possible to put them on hold because connection cannot be restored in the matter of couple of seconds.

Line swapping

In the case of two calls being established in two different lines, one of them is being the active call in the active line. To make the line swapping simpler, active line is swapped automatically depending on call activities change. It can be one of the following scenarios:

• User makes an outgoing call by softphone or desktop phone.
• User retrieves USB held call by softphone.
• User swaps USB call by softphone.
• User accepts an incoming call.
• Call from first active line is ended and other call exists in second inactive line.

The user can also swap the line from the base manually by double clicking the hook-off key or by selecting the line via the UI. When a line is swapped successfully, between two different lines, a visible indication is shown on the base.

Microphone muting

• Microphone muting control is separated into two muting statuses (Fig.25). Each line has its own microphone muting control. When the line is switched, the related microphone muting control will also be switched.

Volume control

• Similar to the microphone, the volume control is also divided into two volume statuses (Fig.26). This means that each line has its own volume control. When the line is switched, the related volume control will also be switched.

Clave Base feature description

• This section aims to introduce you to the available features on the Clave Base. Some of the features will be briefly described through the sections below, whereas the main highlights will be presented via a table with function descriptions (please refer to 12. Appendix B for more details)

Soft client support

• As previously mentioned, the base has support for various soft clients (refer to 3.1 Soft client support)

EHS interface

• The Clave Base supports EHS phones. The base is prepared to be compatible with various EHS standards. This is done by having a slider switch that enables 6 separate HW configurations for the audio routing. The PC Setup tool is used to configure the optimal settings for the SW configuration. (Please refer to 15. Appendix C EHS and DHSG API for details.)

Ringer configuration

• The Clave Base has a built-in ringer for audible alerts for the user. The audio settings of the ringer can be configured via the PC Setup tool or the base menu. The ringer may be muted by selecting “Silent mode” in the PC Setup Tool.

Clave DECT Dongle features

• The RX3741 DECT dongle has many of the same features as the Clave Base station.

Conference

• The Clave DECT Dongle supports internal conference which allows up to three additional headsets to listen-in on and participate in calls controlled by the primary headset of the Clave DECT Dongle.
• The secondary headsets can register on the Clave DECT Dongle before or during the call and will have their microphones muted by default when joining. (Refer to 7. How to connect headset and base station)
• The secondary headset user can unmute the microphone and can then participate actively in the conference call.

The secondary headsets cannot terminate the conference call because the call is controlled by the primary headset, but they can actively leave the call.

A secondary headset is deregistered from the dongle when:

• The headset actively leaves the conference call by long pressing the Multi-Function button
• The conference call is terminated by either the primary headset or the far end (depends on the same setting as above)
• The headset registers back as primary on its own dongle by short pressing the DECT button when idle (not in call)

Soft Client Support

The Clave DECT Dongle combined with one of the four UH headsets supports the audio and USB API of the following applications:

• Skype for Business (aka Lync)
• MS Teams
• Other call clients can be supported
  • require PC tool to be running
  • or UH USB HID API to be supported by call client

Register devices on UH VoIP DECT system

• The following section provides a step-by-step guide on how to register the Clave Base station and Clave Headsets to the UH DECT system.
• IMPORTANT: Both the Clave Base and the Clave Headsets can be SIP registered to the VoIP System. However, depending on which device is SIP registered, the headset has a different behavior. If a headset base is registered to a SIP account (see step 3), then the related headsets can be used in multiple environments – both in VoIP System and normal network. This means that a user can receive VoIP calls and at the same time use the headset for various PC applications, such as listening to music or talking via a softphone (Microsoft Teams). Moreover, these functionalities are available while moving around the VoIP system. However, if a headset is SIP registered as a standalone device (without the headset base), then it can be used only for VoIP calls on the system. (All the other functionalities should still be available via Bluetooth™ to either a phone or PC.)

Register Clave Base

• Step 1 Enter the Management page of an UH DECT Base station and enable the Headset base setting. By doing so, a new menu on the left-handed navigation panel will be added (Headset base)
• Step 2 Navigate to the Headset base page and select the Add headset base option.
• Step 3 A separate editor menu will open for configuration. Fill in the fields and press Save. The available settings are explained in the table below.

changed manually. If IPEI is left at FFFFFFFFFF, any headset base can register at this index. Else, only the headset base with the

specified IPEI number can register to the VoIP system

TERMINAL| No Terminal| This setting enables the administrator to assign a SIP account to the headset base. The following options are available:

No Terminal: No SIP account assigned.

Terminal Idx x: An available extension/SIP account slot which can be assigned to the headset base.

New Terminal: Creates a new terminal/extension slot on the Extensions page with the IPEI of the headset base. The administrator needs to edit the extension details in order to SIP register the headset base.

NOTE: By SIP registering the Clave Base, the user can use the headset both for VoIP calls and for other PC applications (such as music, softphones, etc.)

• Step 4 Mark the newly added headset base and select Register headset base to enable the registration mode.
• Step 5 On the headset base, enter the menu via the scroller (left-hand side) and scroll down to VoIP System
• Step 6 Enter the VoIP system menu and select Register
• Step 7 Enter the Access code (AC)
• NOTE: The Access code (AC), used as an authentication method by the headset base, is placed on top of the page and can be configured by the administrator.
• NOTE : By default, the AC is 0000. You can change the AC code on the VoIP base (See step 4)
• Step 8 The headset base will start the registration process. After a while, it will be registered to the VoIP system.

Register Clave Headsets

• The registration of the Clave Headsets to the VoIP system is done via the Extensions page. The procedure is the same as registering an UH DECT handset. Therefore, please refer to the VoIP System guide and follow the steps for enabling registration mode for the VoIP bases. As soon as you have enabled it, follow the steps below to register the headset.
• IMPORTANT: Due to technical limitations, the Clave Headsets must be free of Clave Base registration before registering to the VoIP system. This means that the headsets must not be present on the Clave Base when registering to the VoIP system.
• NOTE : If a headset is registered to the VoIP system and at the same time you register it to an Clave Base, the connection to the Clave Base will not be stable enough. Therefore, if you wish to have a headset registered both to the VoIP system and to the Clave Base, we recommend registering the Clave Base to the VoIP system (refer to 13.1 Register Clave Base). By doing so, the headset will both support the DECT and other networks.
• NOTE : When using the headset in standalone mode in the VoIP system, it is recommended to charge the device via the USB-C cable attached to an adaptor. Else, if connected to the Clave Base or to a PC, the headset connection might not be stable enough.
• Step 1 Power on the headset via the power slider
• Step 2 Activate the DECT registration on the headset by long pressing the DECT button on the headset until the voice prompt announces “Registering”
• Step 3 After a while, the headset will register to the VoIP base.
