What merging calls means

Merging calls means combining two separate phone conversations into one three-way call so all three people can hear and speak to each other at the same time. You start with one call active, put that person on hold, answer or dial a second call, then press a button or menu option to join both calls together on the same line.

This is different from conference calling, which is usually set up in advance through a service or app. Merging is something you do in the moment during a regular phone call, using features built into your phone or carrier service.

Key Takeaways

  • Merging calls combines two separate conversations into one three-way call using your phone's built-in features.
  • The exact steps depend on whether you have an iPhone, Android phone, or a landline, and what carrier you use.
  • You need call waiting and call merging enabled on your account — most carriers include this at no extra cost, but some older plans do not.
  • If your phone does not have a merge button, you may need to contact your carrier to enable the feature or switch to a plan that includes it.

How to merge calls on iPhone

On an iPhone, the merge button appears automatically when you have two calls active. Start by answering or making your first call. While that call is active, swipe up from the bottom of the screen to see your home screen, then tap the Phone app to return to it. Tap the "add call" button (the plus sign in a circle), then dial the second number or tap a contact. The first caller will be put on hold automatically.

Once the second call connects, you will see a "merge calls" button on your screen — it looks like two overlapping circles. Tap it. Both callers will now be on the same line and can all hear each other. If you need to speak privately to one caller, tap "hold" next to their name, and they will be muted while you talk to the other person.

How to merge calls on Android

Android phones work similarly to iPhones, but the exact appearance of buttons varies by phone model and manufacturer. During your first call, look for an "add call" or plus-sign button on the call screen. Tap it to dial or select a second contact. Your first caller goes on hold.

Once the second call connects, look for a "merge" or "combine" button — on Samsung phones this is often labeled "Merge calls" and appears near the top of the screen. Tap it to join both calls. If you do not see a merge button, your phone model may not support it, or the feature may not be enabled on your account. Contact your carrier to confirm.

Merging calls on a landline or VoIP phone

Landline phones and VoIP services like Vonage or Ooma use different hardware, so the process varies. Most landlines have a "flash" button or a button labeled "call waiting" that you press to switch between calls. To merge, you typically press flash or call waiting, then press a "conference" or "merge" button if your phone has one.

Some older landline systems do not support merging at all — they only let you switch between two calls without joining them. Check your phone's manual or contact your service provider to see what your specific equipment supports. VoIP services usually have merge buttons similar to smartphones, but the location on the screen or handset varies by provider.

What you need to have enabled

Merging calls requires two features on your account: call waiting and call merging (sometimes called "three-way calling"). Most modern phone plans include both at no extra charge, but some older plans, budget plans, or plans from smaller carriers may not.

To check if you have these features, contact your carrier directly — you can find the number on your bill or on their website. Tell them you want to confirm that call waiting and three-way calling are enabled. If they are not, ask what it costs to add them. In most cases it is free or a small monthly fee. If your carrier does not offer these features, you may need to switch plans or carriers.

Why the merge button does not appear

If you have two calls active but no merge button shows up, the most common reason is that call merging is not enabled on your account. The second reason is that your phone model does not support it — very old phones or some budget phones lack this feature. A third possibility is a software issue on your phone.

Start by calling your carrier to confirm the feature is turned on. If it is, restart your phone and try again. If the merge button still does not appear, your phone may not support it. Check your phone's manual or search online for your specific model and "merge calls" to see if it is a known limitation. If your phone should support it but does not, you may need a software update.

What happens when you merge calls

Once you press merge, all three people are on the same call. Everyone can hear everyone else. If one person hangs up, the call continues between the other two. If you (the person who initiated the merge) hang up, the call ends for everyone.

You can still put one person on hold by tapping their name and selecting "hold" — this mutes them so you can speak privately to the other caller. To return them to the conversation, tap "hold" again. If you need to drop one person from the call without ending it for the other two, some phones let you tap their name and select "end call" — but this feature is not available on all devices.

Frequently Asked Questions

Can I merge more than two calls at once?

Most phones support only three-way calls (you plus two others). Some business phone systems and conference calling apps allow more, but standard phone service does not. If you need more than three people, use a conference calling app like Zoom, Google Meet, or your carrier's conference service instead.

Does merging calls cost extra?

No. Call merging is included in most phone plans at no additional cost. You pay only for the calls themselves — the same rate as if you were talking to one person. If your plan does not include three-way calling, your carrier may charge a small monthly fee to add it, but this varies by provider.

What if one person cannot hear the others after I merge?

Ask the person who cannot hear to check their phone volume and make sure they did not accidentally mute themselves. If that does not work, hang up and try merging again. If the problem keeps happening, it may be a network issue on their end or a problem with your phone's microphone or speaker.

Can I record a merged call?

This depends on your state or country's laws. Many places require all parties to consent to recording before you start. Check your local laws before recording. Some phones have a built-in recording feature, but others do not — if yours does not, you can use a third-party app, though you must still get consent from everyone on the call.

Why does my phone drop one caller when I try to merge?

This usually means your phone lost the connection to one of the calls, or your carrier's network had a brief interruption. It can also happen if you pressed the wrong button by accident. Try making both calls again and look carefully for the merge button before pressing anything else.
