Trying to make an outgoing call and having issues connecting? Are you receiving a “call failed” error? In this guide, we put together all of the possible causes to help you diagnose and resolve.
Possible reasons
Connection issues
As a VOIP phone, OpenPhone requires a strong internet connection, either via WiFi or data, to work properly. If you do not have a reliable connection, it’s possible that you will not be able to make an outbound call. In these cases, we’d recommend to try changing to a different internet source (e.g. WiFi to data or vice versa) or, if using WiFi, reset your router.
It’s also possible that a third-party extension, firewall, or VPN can be blocking your connection, resulting in the above issue. If this is the case, you may want to try disabling to see if that resolves the issue.
The destination you are calling is busy or out of service
While we try our best to surface error messages as to why a call may fail, we sometimes don’t receive an error message from the other carrier. In these cases, it’s possible that the number is out of service or temporarily unavailable to receive calls. It’s also possible that the destination has blocked your number.
If you are only having issues in calling some but not all numbers, then it’s likely that the source of the issue is the number that you’re calling. Please check the number and ensure that it is in service before calling again.
If you’ve ruled out the above possible sources of the issue, then please do not hesitate in reaching out to our support team. We’re happy to help investigate what’s going on. Please submit a request
