How to Tell if Someone is on Another Call iPhone?

Being unable to get through to someone because they are already on a call might be irritating.

You might want to know if someone using an iPhone is on another call. It can help you determine if it’s the right time to reach out or if you should wait for a better moment, potentially saving you from interrupting an important conversation.

In this article, we’ll look at several techniques and signs that can tell you if someone is using their iPhone to make another call. 

How to Know Someone is on Another Call iPhone?

It’s frustrating to call someone only to find out they are currently on another call. However, there are several techniques you may use to figure out if someone is using their iPhone to make another call.

These can range from explicit alerts to subtler hints based on call behaviors. Let’s explore them in detail.

1. Call Waiting

Call waiting is one of the most widely used functions on iPhones. Users can receive incoming calls while on a call when call waiting is turned on.

You can hear a beep or receive a message that someone’s line is busy if they are on another call. This is a good indicator that they are engaged in a conversation.

2. Busy Signal

When you attempt to call someone, and they are already engaged on another call, you may encounter a busy tone. This is a recurring beep that suggests the line is currently in use.

Alternatively, you might hear an automated message informing you that the person you’re trying to reach is on another call. These are clear and direct indicators that the person you’re trying to reach is engaged on another call.

3. Voicemail

Calls that come in while a person is on another call and call waiting is not turned on may be routed to voicemail.

When you contact them, if you get their voicemail right away without the phone ringing, it’s a good sign that they are on the phone with someone else. You can try contacting them later or leave a message.

4. Call Forwarding

When call forwarding is set up, it allows incoming calls to be redirected to another number. If someone has this feature enabled and a call comes in while they’re already on a call, the incoming call could be forwarded to another number.

If your call is immediately forwarded to voicemail or another number, it could suggest that the person you’re trying to reach is on another call.

5. Ring Patterns

Generally, when you make a call, you’ll hear a series of rings while waiting for the other person to pick up that call. This is known as the ring pattern.

 If the ring pattern changes, it could indicate that the person is on another call. For example, if the ring is shorter, followed by a long silence, it could mean that the person you’re trying to reach is on another call.

6. Dropped Call 

A dropped call occurs when a call ends unexpectedly due to technical reasons. This is often due to network issues but can also occur if the person you’re calling switches to another call.

If your call unexpectedly drops , it might indicate that the person you’re calling has switched to another call.

Factors that Could Create Similar Indications

Various factors could lead to similar indications as someone being on another call. These could range from network issues to specific phone settings.

It’s crucial to distinguish these factors from the signs of someone being on another call to avoid misunderstandings.

1. Poor Network Coverage

 Poor network coverage can significantly affect call signals, leading to unexpected drops, poor audio quality, or difficulty connecting calls. This common issue occurs when the signal strength is low or unstable.

Poor network coverage can lead to calls being dropped or sent to voicemail, which might incorrectly suggest that the person you’re calling is already on a different call.

2. Do Not Disturb Mode

The Do Not Disturb (DND) mode is a setting on the iPhone that mutes all calls, alerts, and notifications on your device. It’s typically used when the user doesn’t want to be disturbed, such as during meetings or while sleeping.

If someone has enabled DND mode, any calls you make will be sent directly to voicemail, potentially giving the impression that they’re on another call.

3. Other Technical Glitches

Smartphones, including iPhones, can sometimes experience technical glitches. These can range from software issues, such as problems with the operating system or call software, to hardware issues, such as problems with the microphone or speakers.

Technical glitches can cause various symptoms, including dropped calls, poor call quality, and problems connecting calls. These symptoms could potentially be mistaken for signs that the person you’re trying to reach is on another call.

Being aware of these factors can help you correctly identify when someone is actually on another call versus when other issues might be interfering with the call. 

Tips on Distinguishing Other Issues from Someone Being on Another Call

  1. Consider the context: If you’re trying to call someone and you know they’re in a meeting or at an event, it’s more likely they’re on another call or have their phone set to Do Not Disturb mode.
  2. Repeat call attempts: If you suspect someone is on another call, you might try calling again after a few minutes. The ring pattern and response should return to normal if the person is no longer on a call.
  3. Check for network issues: If you’re experiencing dropped calls or poor call quality, check your network signal strength. A weak signal could be the cause of your call issues.
  4. Consider phone settings: Remember that some people set their phones to send all calls to voicemail, or they may use Do Not Disturb mode regularly. This can mimic the signs of someone being on another call.

Considerations About Respecting Others’ Privacy

While knowing whether someone is on another call is helpful, it’s also important to respect their privacy. Repeatedly calling someone or trying to deduce their phone usage could be seen as intrusive.

If someone isn’t answering their phone, consider leaving a voicemail or sending a text message and waiting for them to return your call when they’re available.

Remember, while these tips can provide a guideline, none of these methods are foolproof. Some situations will remain ambiguous due to the nature of network variations and personal phone settings. It’s best to use these indicators as guides rather than absolute truths.


Trying to reach someone while they are using their iPhone on another call can be time- and frustration-consuming. 

You can learn more about someone’s call activity by analyzing busy tones, listening for voicemail redirection, using call waiting indicators to recognize changes in ring patterns, and paying attention to status indicators.

However, it’s also important to consider factors like network coverage, Do Not Disturb mode, and other technical glitches, which can create symptoms similar to those of someone being on another call. Misinterpretation can lead to confusion or miscommunication.

Use these channels to efficiently communicate and prevent pointless interruptions while keeping in mind respecting the privacy and availability of others.
