Troubleshooting

This issue is often caused by the SIP ALG (Application Layer Gateway) feature that is enabled by default on many home routers. Some routers (especially brands like ZTE) try to “assist” by modifying audio packets, but in doing so they may miscalculate the Content-Length or corrupt the packet format. For security reasons, our servers reject these malformed packets. Solution: Disable the “SIP ALG” feature in your router settings if possible, or try switching from Wi-Fi to mobile data (4G/5G).

Make sure you enter phone numbers in international format, starting with “+” and the country code.

This is almost always related to internet connectivity. Check that your connection is stable. If you are using a Bluetooth audio device (headphones, speakers, etc.), verify the selected audio source from the speaker icon on the call screen.

The per-minute rate for the destination country may be higher than your current balance. For example, if you have $0.10 but the rate is $0.15 per minute, the call cannot start. Also ensure that your internet connection allows VoIP calls, as some regions may restrict them.

You can reach us via the in-app menu under Other > Help > Contact Us, or by emailing support@telicall.com.

This is caused by the internet connection in 90% of cases. Check that your connection is working properly.

It can take a few minutes for the App Store or Google Play to approve the payment. Wait a moment and restart the app. If the problem continues, contact us at support@telicall.com.

This is usually caused by a momentary loss of internet connection. Try switching from Wi-Fi to mobile data, or vice versa. If it keeps happening, report it to us at support@telicall.com.

Check that notification permission has been granted to Telicall in your device settings. On iOS: Settings > Telicall > Notifications. On Android: Settings > Apps > Telicall > Notifications.

This is usually related to background permissions. Try the following: On Android, turn off data saver for Telicall and allow the app to run in the background. Check your internet connection and switch between Wi-Fi and Mobile Data. Fully close and reopen the app. If the issue continues, contact us at support@telicall.com.

This can be caused by your internet connection or by a security check being active on your account. First switch between Wi-Fi and Mobile Data and restart the app. If the issue continues, send the step where it happens and the message you see (with a screenshot if possible), along with your account email, to support@telicall.com.

When unusual calling activity that may violate the Terms of Service is detected on your account, your usage is reviewed. During this period, some calling features may be temporarily slowed down or limited as a security and anti-abuse measure. If misuse is confirmed, your account may be permanently closed. If you’re experiencing this and believe the decision is incorrect, you can contact us at support@telicall.com.

When unusual calling activity that may violate the Terms of Service is detected on your account, your calls may be temporarily restricted. To avoid this, please make sure your usage complies with the Terms of Service and does not involve any misuse or harassment.

First, make sure you placed the call using the second number that comes with the plan. Calls made using the Telicall Number or another number without that plan will not use its minutes. This can also happen if you’ve run out of calling minutes, your subscription is suspended, or the type of line you called (mobile or landline) isn’t covered by your plan. If the problem continues after these checks, contact us at support@telicall.com.

The number you selected may have been taken by another user in the meantime. You can select a different number from the list to continue.

Your subscription has started, but the number you selected is currently unavailable. You can tap “Select a New Number” to choose another number. Since your subscription has already started, you won’t be charged again for this step.
