Make a Conference Call

A conference call lets three or more people speak in the same live conversation. You can create one from a phone, a business calling app, or a meeting platform such as Microsoft Teams, depending on what your device, carrier, and organization support.

Choose the Right Type of Conference Call

Before starting, decide what kind of conference call you need. A traditional phone conference call uses cellular or phone network calling and usually works through Add Call and Merge buttons. A business conference call uses a platform such as Microsoft Teams, Zoom, Google Meet, Webex, or a VoIP phone system. A hybrid meeting may include both internet participants and dial-in phone participants. The right choice depends on how many people are joining, whether you need video, whether screen sharing matters, and whether participants are inside or outside your organization.

For a quick three-person discussion, a phone-based merge call may be enough. For a client meeting, training session, project review, or recorded discussion, a meeting platform is usually better because it gives you calendar invitations, participant controls, chat, screen sharing, and a join link. For sensitive business conversations, use your organization’s approved platform and follow its security rules.

Also check limits. On iPhone, conference calling depends on carrier support and may allow up to five people in many cases. On Android, the interface varies by device, carrier, and calling app. In Microsoft Teams, meeting capacity and dial-in options depend on your license and admin settings. A good host checks these limits before inviting a large group.

Make a Conference Call on iPhone

To make a phone-based conference call on iPhone, call the first person and wait for the call to connect. Then tap the option to add another person. Depending on the iOS version and carrier interface, this may appear as Add Call, Add People, or through a More menu. Select or dial the second person and wait for that call to connect. When both calls are active, tap Merge to combine them into one conference call.

Repeat the process to add more people if your carrier supports it. The person who starts the conference call usually controls the call and may be able to add, merge, or disconnect participants. If you do not see the merge option, your carrier or plan may not support that feature, or the current call type may not allow merging.

If someone calls you while you are already on a conference call, you may be able to accept the incoming call and then tap Merge to add them. Be careful with this in professional settings. Tell the current participants before adding someone new, especially if the conversation is confidential.

Make a Conference Call on Android

On Android, the steps are similar but the exact labels vary. Open the Phone app, call the first person, and wait for them to answer. Tap Add call, put the first caller on hold, dial or select the next person, and wait for the second call to connect. Then tap Merge to join the calls. On some Samsung Galaxy phones, the buttons are clearly labeled Add call and Merge. On other Android devices, the options may sit behind a menu.

If you use Google Voice with a supported work or school account, you may be able to merge two calls into a three-way call. Some services do not allow merging emergency calls, directory assistance, or calls to your own number. If the merge button is missing, check your calling app, carrier plan, and account type.

As with iPhone, the host should confirm consent before adding people. A conference call can quickly become confusing if participants do not know who is present. Start by naming everyone on the line and explaining the purpose of the call.

Create a Conference Call with Microsoft Teams or Another Meeting App

For business calls, a meeting app is often cleaner than merging phone calls manually. In Microsoft Teams, create a meeting from the calendar, add required attendees, set the time, and send the invitation. Participants receive a join link, and depending on your organization’s setup, they may also have a dial-in number. During a Teams meeting, you can invite more people from the participant panel. Some Teams phone configurations also allow the host to dial a number and merge that call into the meeting.

In Zoom, Google Meet, Webex, and similar platforms, the pattern is similar: create a meeting, invite people, share the link, and manage participants from inside the call. Use a calendar invite when possible. A link sent in chat can work for informal calls, but calendar invitations reduce confusion because they include date, time, time zone, and topic.

If participants are external, test the link and access settings. Some organizations block certain meeting tools, and some guests may need browser permissions for microphone and camera. A dial-in backup is useful when someone has poor internet.

Prepare Before the Call Starts

A conference call is easier when the host prepares. Send the agenda or purpose in advance. Include the time zone, joining method, phone number or link, access code if needed, and expected duration. If the call requires documents, attach them or link to them clearly. If a decision is needed, state the decision in the invite so people arrive ready.

Test your microphone, speaker, headset, battery, and internet connection before the call. Join from a quiet place when possible. If you are hosting from a phone, make sure you have enough signal and battery. If you are hosting from a meeting app, close unnecessary apps and open the files you plan to share.

Have a backup plan. A backup can be a dial-in number, a second meeting link, a short email summary, or a direct phone number for the host. Professional calls do not need perfection, but they do need recovery options.

Host the Call Professionally

Start by welcoming participants and confirming who is on the line. If the group is large, ask people to mute when they are not speaking. State the purpose, time limit, and desired outcome. For example: “We have thirty minutes to confirm the launch date, assign the final tasks, and identify any blockers.” That opening gives the call direction.

Use names when inviting input. Audio-only calls can make it harder to read the room, so do not assume silence means agreement. Ask clear questions: “Sara, do you see any legal risk?” “Omar, can your team deliver by Friday?” “Does anyone object to option two?” This keeps the conversation active and prevents hidden disagreement.

Take notes or assign a note taker. Capture decisions, owners, deadlines, and open questions. End with a summary so everyone leaves with the same understanding. A conference call without a recap often creates more meetings later.

Troubleshoot Common Problems

If you cannot merge calls, the carrier, plan, device, or calling app may not support conference calling. Try using a meeting platform instead. If someone cannot hear, ask them to reconnect, switch audio devices, or dial in by phone. If there is echo, one participant may be using speakerphone near another device. Ask people to mute or use headsets.

If a participant cannot join a Teams or Zoom call, check whether they have the correct link, whether the meeting time zone is correct, and whether they are waiting in the lobby. If screen sharing is needed but blocked, check presenter permissions and local device permissions. If the call drops, send a quick message with the backup link or number.

For important calls, do not spend fifteen minutes troubleshooting with the whole group waiting. Move to the backup plan, continue with the available participants, or reschedule with a clear next step.

Conference Call Etiquette

Good etiquette makes a call feel professional. Join on time. Use a quiet location. Mute when not speaking. Say your name before speaking if people may not recognize your voice. Avoid multitasking, typing loudly, eating, or taking the call from a noisy place. If you need to leave early, tell the host in advance.

If the call is recorded, announce it and follow policy. If the topic is confidential, do not add people without permission. If you are driving, prioritize safety and avoid taking notes or managing complex meeting controls. If you are the host, keep the call moving and protect the time of everyone on the line.

A conference call succeeds when the technology disappears and the conversation produces a clear result.

Final Thoughts

To make a conference call, choose the right method, invite the right people, prepare the joining details, start with a clear purpose, manage participation, and end with action items. Phone merge calls are useful for small conversations. Meeting platforms are better for larger, scheduled, or business-critical discussions.

The best hosts think beyond the button. They make the call easy to join, easy to follow, and easy to act on afterward.

FAQs

Why do I not see the Merge button?

Your carrier, phone plan, device, or calling app may not support call merging for that situation. Try a meeting app or contact your provider.

How many people can join a phone conference call?

It depends on the carrier, device, and plan. Many iPhone conference calls support up to five people, but you should verify your provider’s limit.

Is a conference call the same as an online meeting?

Not always. A phone conference call is audio-based through calling features. An online meeting may include video, chat, screen sharing, recording, and calendar invitations.

Conference calling features vary by carrier, device, app, country, license, and organization policy. Verify your exact limits before important calls.
