What’s About

The XCALLY Motion WebRTC Bar (Web Real Time Communication Bar) is a native application embedded in the Omni Desktop Interface.

The WebRTC can be used by the Contact Center Agents, who have been configured as WebRTC Agents, and so able to manage incoming and outgoing calls.

If you need to enable your Agents to use the WebRTC feature, please contact the XCALLY Sales Team.

It is impossible to use WebRTC as Users

Requirements

You don't need to install any software on the Agent workstation, but you must meet the following requirements:

You must install a valid HTTPS certificate: you need a VALID SSL certificate provided by an official Certification authority (the use of a Self-Signed certificate is not enough and will not make the WebRTC working)
From Chrome Version 110.0.5481.78, it is required to configure the STUN Server on the XCALLY Networks Settings to use the WebRTC properly
The Agent PC has proper audio devices
You need a WebRTC specific license to make it work
If your Motion Server is behind NAT, remember to configure the STUN server
The Agent who logs in must be configured as WebRTC Typology
The Web Socket Service Port 8089 must be open on your server
UDP: ports 10000 up to 20000 must be open
The Browser on the Agent Desktop must be: Opera, Chrome or Safari
OS must be one of the following: MAC OS, MS Windows from 10 on, Linux OS, Chrome OS, Chromium OS

XCALLY Public STUN servers

You have the opportunity to use our public STUN servers.

Please note, this service is public and free without any warranty or support.

Check which one is the nearest to your location:

To verify correct communication with the stun server, you must execute this command on root user: asterisk -rx "stun show status"

If successful, the following message will be displayed:
Hostname eu-stun.xenialab.com
Port 15349
Period 30
Retries 3
Status OK
ExternAddr 35.178.170.143
ExternPort 43745

This is how the WebRTC displays:

To check if Agent's PC local requirements are met:

Access into XCALLY from the WebRTC Agent PC
Click on the Agentname: from the drop-down menu, select Settings
Check the Requirements section:

If all of them are tagged with a green checkmark, the local configuration is ok
If one or more of them are tagged with a red checkmark, the corresponding requirement is not properly configured/working.

Troubleshooting

To ensure that you are using a compatible browser with WebRTC services, there are many tools available.
For example, you might use this tool to see if your browser is suitable or not for WebRTC use:

Jabra USB Headphones

This section is dedicated to Agents using Jabra USB Headphones on the WebRTC bar (only for MAC/Windows using Chrome).

All professional Jabra headsets and Jabra speakerphones are supported. (i.e. Jabra Evolve series, Jabra Pro series, Jabra Biz series, and Jabra Speak series).

Your Agents can use Jabra Headphones remote control to perform the actions usually executed clicking the WebRTC Bar buttons like: Accept, Hold, Hang-up, Volume up/down, Mute on/off.

To configure this device, you have to do the following activities in sequence for all the PCs involved:

Install a Driver on all the PCs used by the Agents that you can find in the following links:

Debugging in the browser

For debugging purposes you may enable different levels of debugging, these logs will be located on the server in /var/log/xcally/client/ in a folder named as the agent username:

By default, WebRTC logs nothing to the browser console. To enable debugging, run the following command in the browser console and reload the page:

JsSIP.debug.enable('JsSIP:*');

Note that the logging settings get stored in the browser LocalStorage. To disable it, run the following command in the browser console and reload the page:

JsSIP.debug.disable('JsSIP:*');
