Resolve Microsoft Teams call drops with our comprehensive guide. Troubleshoot internet connectivity, optimize network, update software, and adjust firewall settings.


I understand the frustration of experiencing call disconnects or dropouts while using Microsoft Teams. A stable and reliable communication platform is crucial for seamless collaboration and productivity. In this comprehensive guide, we will address the issue of call disconnects and provide practical solutions to help you overcome this challenge. Let’s dive right in!

Understanding the Problem

Call disconnects or dropouts can occur due to various factors, ranging from network issues to device compatibility problems. It is essential to identify the root cause of the problem before implementing the appropriate solutions. Here are some potential culprits to consider:

1. Internet Connectivity

A stable and fast internet connection is essential for uninterrupted Microsoft Teams calls. Slow or intermittent internet connectivity can result in call dropouts. Ensure that you have a reliable internet service provider and perform a speed test to determine the quality of your connection.

2. Network Congestion

High network traffic can cause call disruptions in Microsoft Teams. This issue often arises during peak hours when many users are simultaneously accessing the network. Consider scheduling important calls during off-peak hours to minimize the chances of call dropouts.

3. Hardware and Software Compatibility

Outdated or incompatible hardware and software configurations can lead to call disconnects. Ensure that your computer or mobile device meets the minimum system requirements for Microsoft Teams. Additionally, keep your operating system, drivers, and Teams app up to date to ensure compatibility and optimal performance.

4. Firewall or Security Settings

Sometimes, overzealous firewall or security settings can interfere with Microsoft Teams’ communication protocols, causing call disruptions. Review your firewall and security configurations to ensure that they do not unnecessarily block or restrict Teams’ functionality.

Solutions to Prevent Call Disconnects

Now that we have identified potential causes, let’s explore the solutions to mitigate or resolve call disconnects in Microsoft Teams.

1. Check and Improve Your Internet Connection

To ensure a stable internet connection, follow these steps:

  • Connect your device directly to the modem or router via an Ethernet cable for a more reliable connection.
  • Avoid using public Wi-Fi networks, as they tend to be less stable.
  • Close bandwidth-intensive applications or downloads running in the background to allocate more network resources to Microsoft Teams.

2. Optimize Your Network

To minimize network congestion and enhance call quality:

  • Prioritize Microsoft Teams traffic on your network router. Consult your router’s user manual or contact your network administrator for assistance.
  • If possible, connect to a 5GHz Wi-Fi network instead of a 2.4GHz one, as it offers better bandwidth and less interference.
  • Consider upgrading your internet plan to a higher speed or switching to a more reliable internet service provider.

3. Update Hardware and Software

Ensure your device meets the minimum system requirements for Microsoft Teams. Additionally:

  • Update your operating system, drivers, and firmware to the latest versions.
  • Install the latest Microsoft Teams app from the official website or your device’s app store.
  • Verify that your audio and video peripherals (e.g., headphones, microphones, webcams) are compatible and have up-to-date drivers installed.

4. Adjust Firewall and Security Settings

To prevent firewall or security settings from interfering with Microsoft Teams:

  • Whitelist or allow-list Microsoft Teams’ executable files in your firewall or antivirus software.
  • Disable any unnecessary VPN or proxy services that might impede Teams’ communication.
  • Consult your IT department or network administrator if you require assistance with firewall or security settings.


By following the troubleshooting steps outlined in this guide, you can address the issue of call disconnects or dropouts in Microsoft Teams. Remember to consider factors such as internet connectivity, network congestion, hardware and software
