The "Unable to establish call" error is displayed if a call ended before reaching the agent and our system was unable to identify the exact disconnection reason: it could indicate that the caller disconnected the call or that another agent already picked up the call. In case the issue is affecting several agents in your call center, it could indicate poor or interrupted internet connectivity.
We recommend that you reestablish your internet connection and refresh the page. If this does not solve the issue:
- Confirm that all systems are operational on our side by visiting Talkdesk status page.
- Make sure that you are using an Ethernet connection and not WiFi.
WiFi lacks reliability for voice communications as it is prone to increased latency and interference from other devices.
Please check this article for more information on why we strongly recommend using an Ethernet connection.
- If an Ethernet connection is not available yet, use a 5GHz router instead of a 2.4GHz one.
- Close any apps that may be unnecessarily using your bandwidth up.
If you are still experiencing issues:
- Check with your IT department or network administrator. We recommend configuring and optimizing the internal network according to these guidelines.
- Check with your ISP.
