Introduction

How to connect your Jabra PRO with the Maxwell 10

Gigaset tested this with the following devices.

• Maxwell 10 Software 1.2.0 and 1.2.18, Hardware version 28 or higher is needed.
• Jabra PRO 9470
• Jabra Link 14201-10 DHSG cable.

Gigaset cannot support you with questions about the Jabra Headset, for this contact your supplier.

Connection

• Plug the 1-sided end of the DHSG cable into the Maxwell EHS socket.

• Insert the RJ9 plug of the DHSG cable into the headset base socket marked with a "phone" symbol and the RJ45 plug into the socket marked with "AUX".

Then follow the instructions of the Jabra PRO base SmartSetup Wizard.

Select phone settings, "Desk phone", then "Connect to a desk phone?", "Manual".

Select adapter type "DHSG"

Set the phone setup switch to position "A".

We recommend setting the microphone volume to 6 out of 13.

Signalling of incoming call (Ringing in headset)

The Maxwell 10 has a "HEADSET ON/OFF" setting that has the following function:

In the right top corner of the Maxwell 10, pulldown the settings menu and via the menu:

Headset ON - Ringing audio played via Headset during incoming ring.

Headset OFF - No audio signalling in Headset when receiving call.

This feature is implemented for 3e Party Audio support, and plays the ringtone like it is normally done via the speaker. But it also means that to play this ringing signal, the headset connection has to be enabled. When you try to answer the call, then the Headset connection will be disabled because it was already active. You need to press again to answer the call. The recommended setting for EHS headsets is to disable this feature.

Open Improvements

Other side disconnects the call, headset will be switched off/on/off

The reason is that the Maxwell receives a disconnect that will also disconnect the Headset connection.

Because after disconnect, a 5 seconds audio disconnect signal is played (to inform the user via audio), the headset connection is re-activated during this time.

Then the Headset connection is disconnected.

We will make a change in the 1.2.20 software version that the disconnect signal will not be played anymore.

When receiving a call, the headset will be switched On/Off/On

This is related to the used audio codec and happens when codec G.711 is used.

By default, EHS will be opened in Wide Band (WB / G.722) and will change to Narrow Band (NB / G.711) after call is connected and if G.711 codec is negotiated between DUT and User A. For this the headset connection is switched Off and On again.

Solution is to use only the G.722 codec. A future change in the Maxwell 10 is planned to improve this.
