Hi! I see you're having an issue where your imo call rings but then cuts out. I’d like to help you get this fixed. Just to understand better: when you say it rings and cuts out, does the call disconnect on its own right after the ringing, or does it fail as soon as the other person answers? Also, is this happening with all your contacts or just specific ones?

Generally, this type of issue often relates to network connection instability, but there might be other causes. Meanwhile, here’s a simple step-by-step guide you can try on your Windows device to troubleshoot this:

1. Check Internet Connection: Since imo calls need a stable internet connection, please test your current connection speed using a service like speedtest.net. A slow or unstable connection can cause calls to drop.

2. Switch Networks: If you are on Wi-Fi, try switching to a different Wi-Fi network or use a wired Ethernet connection if possible to see if that stabilizes the call.

3. Close Background Apps: Ensure that no other apps are heavily using your bandwidth (downloads, streaming) during your calls.

4. Update imo app: Make sure you are running the latest version of imo on your device. If you are using imo in a browser (WebKit), try refreshing the browser, clearing cache, or using the latest browser version.

5. Restart Your Device: A simple restart can refresh your network settings and clear minor glitches.

If you’ve tried all these, or the calls still cut out immediately after ringing, it might be related to device compatibility or server issues. Please let me know how these steps go, and we can dive deeper if needed!

Are you satisfied with this guidance so far?
