Why Did My Call Fail?

No one answered

Shows as: timeout, no_answer

Your call went through successfully and rang on the other person's phone, but they did not pick up. This is not a problem with BubblyPhone — the call worked correctly on our end. The phone rang, but nobody answered it. Try calling at a different time, or check that you have the right number.

You cancelled the call

Shows as: originator_cancel

You hung up before the other person answered. The call was connecting normally — you ended it before they picked up. This often happens when you redial quickly or change your mind while the phone is still ringing. There is nothing wrong with the service.

Line was busy

Shows as: user_busy

The person you called was already on another call. Their phone line was occupied, so your call could not be connected. Try again in a few minutes.

Call was rejected

Shows as: call_rejected

The recipient's phone or their carrier rejected the incoming call. This can happen for several reasons: they may have spam call filtering enabled on their phone, their carrier may block international calls by default, or certain countries have restrictions on incoming calls from VoIP services. If you know the person, ask them to check whether their phone is set to block unknown or international numbers.

Number does not exist

Shows as: unallocated_number, not_found

The phone number you dialed is not in service or does not exist. Double-check the number carefully, digit by digit. Make sure you selected the correct country code from the dropdown. Remember to drop the leading zero from local numbers. For example, if the UK number is 020 7946 0958, you should enter 2079460958 after selecting +44. See How to Make International Calls for more dialing examples.

Connection failed

Shows as: webrtc_connection_failed

Your browser could not establish a connection for the call. This is typically caused by your internet connection, network settings, or browser configuration — not by BubblyPhone. Here are things to try:

• Switch to Wi-Fi instead of mobile data.
• Use Chrome or Firefox, which have the best WebRTC support.
• Close other apps that might be using your microphone, such as Zoom, Teams, Discord, or FaceTime.
• Use the Test Connection feature in the Dialer to check your setup before calling.
• If you are on a phone or tablet, try our iOS or Android app for a more reliable connection on mobile devices.

Network issue

Shows as: network_out_of_order, normal_temporary_failure

There was a temporary problem with the phone network in the destination country. This is a telecom infrastructure issue that is completely outside of BubblyPhone's control. It could be caused by congestion, maintenance, or a local outage. Try your call again in a few minutes. These issues are almost always temporary.

Call timed out

Shows as: recovery_on_timer_expire

The call took too long to connect. This can happen with certain international routes, during peak hours when phone networks are congested, or when routing through multiple carrier networks. Try calling again. If it happens repeatedly to the same number, the issue may be on the recipient's carrier side. For technical details, see SIP Error Codes Explained.

Destination out of order

Shows as: destination_out_of_order

The number you called appears to be temporarily out of service. The issue is on the recipient's end — their phone may be turned off, disconnected, or experiencing a service disruption. Try again later, or reach the person through a different method to confirm their number is still active.
