Softphone in the Puzzel Agent Application (PAA) - Basic Information

Softphone is embedded in the Puzzel Agent Application (, enabling agents to answer calls without using an external phone, landline or mobile.

Softphone is a cost-related feature and requires activation by Puzzel. Softphone can be activated on some or all agents. Please contact your key account manager for further information regarding prices and cost.

Note that this is a new softphone-solution with other technical requirements than our softphone-solution in the current agent application. Please read our basic requirements document(requires sign-in) for details regarding firewall settings and relevant ports/ip-addresses. It is recommended to start testing softphone with one or two agents to begin with and eventually extend the number of users.

Facts and Features

  • Softphone utilizes WebRTC technology to carry the conversation's audio through the agents internet browser and internet connection.
  • Softphone requires that agents have stable and sufficient internet access, and it is recommended to estimate 100kbps per softphone call on a wired internet connection.

  • Softphone is only supported on newer versions of the Chrome internet browser on desktop devices.

  • The audio in conversations through softphone is handled through a headset and microphone connected to the agents computer, typically via USB.

  • In the "Settings" tab, agents can toggle between logging on with Softphone or an external phone (landline or mobile).

How to get started

When the softphone-feature is activated in the administration portal, agents will see a new menu-option in the "Settings" tab. Here, agents can first of all choose if they 1) want to use Softphone or not, but also set the ringer-options, meaning where the Softphone should play the ringing tone. If you want Softphone to ring on your PC, in addition to your headset, you can define this here.

Audio setup

For handling softphone calls, the agent application uses the audio device defined in your browser and operating system.Before logging on to the queues with softphone, be assured that a headphone device, suitable for communication is plugged into the desktop device.

Your Operating System

Your headphone device should appear in your audio settings on your PCs system tray, where you can test the device and set relevant definitions. It is recommended to set your headphone device as the "Default Device", and your PC speakers as "Default Device", if this is not already set. This applies for both the Playback- and Recording settings.

The PC's "Default Device" are related to the settings you soon will be making in the Puzzel client.

Windows 10

In the below example, Jabra Link 380 headset is used.



Windows 11

For Windows 11, please make sure your preferred headset are set under System --> Sound and System --> Sound --> Volume Mixer in your operating system.

Puzzel Softphone is hardware agnostic, in the sense that no specific audio hardware is known to 'work better' with our software than any other. However, we still get many questions from our customers about what headsets we recommend agents use. We can't offer any such recommendation beyond simple guidelines, but we can tell you what headsets our own agents use:

  • Plantronics Voyager Focus UC B825-M (wireless)
  • Jabra EVOLVE 40 MS Stereo (wired)
  • Jabra EVOLVE 65 MS Stereo (wireless)

As for simple guidelines, a good option may be to simply look for well-reviewed gaming headsets. These are designed to be worn comfortably for many hours, and audio quality from both the microphone and speakers is key. Those are the key things to look for: comfort and audio quality. The headsets we have mentioned specifically above are not gaming headsets, but they are the ones we use and are happy with.

Support and Troubleshooting

If you are having problems using softphone, double check your audio settings on both your PC and in the Agent Application first. You can also contact your supervisor who again will consider further actions and perhaps contact Puzzel Support if necessary. We have some known issues below that might be similar to your problem:

  • Issues with softphone could occur on Puzzel's side and we will immediately notify subscribing administrators about it. This is rare and if you experience issues without us notifying you please check your local settings. Please ask your local IT team to check relevant settings in our Basic Requirements
  • Please also verify that there are no local Internet connectivity issues and that no local IT changes have been applied, which could impact connectivity to the Puzzel Softphone service. If you require any further assistance from Puzzel, please contact Puzzel Support.
  • Workaround - Take a note of the callers phone number and tell him or her that you'll call them back (remember that the caller can possibly hear you).
  • It is likely that you cant answer and hang up softphone calls or adjust the volume through the controls/button on the headphones USB cable. This is because so called HID events (actions triggered by a USB device) apparently aren't supported yet in Chrome or other browsers. We are following Chrome for the support for this feature, since i is relevant for most softphone users.

For more technical details and requirements regarding Puzzel Softphone, please read our basic requirements document found here.
