*Zoom and services that include the name Zoom are services provided by Zoom Video Communications, Inc.

From July 15, 2022, Zoom will have a 40-minute limit even for meetings with two participants if you have a free subscription. (Previously, it was only for meetings with 3 or more people.)
Companies and organizations using Zoom for business should consider switching to a paid license at this opportunity. 

Zoom is often used on computers, smartphones, and tablets, but if you use the dial-in function, you can also participate in meetings with conventional telephones (mobile phones and landlines).

This article explains how to use Zoom by dialing in and how it differs from calling over the Internet.

Let’s check how to set up dial-in so that you can participate in Zoom even if data communication is not possible.

Cases where using Zoom by dial-in is effective

Cases where using Zoom by dial-in is effective
Dial-in is the ability to join a Zoom meeting using your phone number.

First, let’s take a look at the main usage scenarios, in what cases the dial-in function is useful.

Join a meeting from a mobile phone/landline

In the following cases, you cannot participate in the meeting from a computer or smartphone.

  • The computer does not come with a microphone/speaker (= voice cannot be exchanged)
  • I don’t have a smartphone/tablet

In such cases, voice calls can be used by joining Zoom from a traditional mobile phone or landline.

However, in the case of dial-in, only voice calls are possible, and functions such as video calls and screen sharing are not available.

Therefore, it is recommended to join Zoom from a computer and a phone, and share the screen and make a voice call at the same time.

The case where the speed limit is applied on the smartphone

Zoom video calls are performed by data communication, and consume smartphone capacity if there is no WiFi environment.

Therefore, if data communication is restricted due to lack of capacity, even if Zoom is started, it may become unstable, such as lag in conversations or distorted images.

If there is no problem with only voice calls, it will be smoother to join using dial-in .

Long meetings can get expensive, so be careful not to overspend if your mobile calling plan isn’t unlimited.

Also, when using dial-in, if the global dial-in area is set to an overseas country such as the United States, Hong Kong, or China, an international call will be made.

International calls can be expensive, so it is important to review your region settings before using .

The procedure for changing and checking the global dial-in setting to “Japan” is as follows.

  1. Go to the Zoom website and sign in
  2. Click “Settings” from the left menu on the My Account page
  3. Scroll down to Global Dial-in Countries/Regions in the Teleconferencing tab
  4. Click Edit (pencil mark) next to Country (default is United States)
  5. Check “Japan”
  6. Click the “X” next to “United States”
  7. Make sure the default dial-in country/region is “Japan”
  8. Click “Save”

No need to dial in when video calling is possible

No need to dial in when video calling is possible
There is no need to use dial-in if a microphone and speakers are included and you can use Zoom with just a computer, or if you are in an environment where smartphone data communication is available.

Dial-in incurs call charges, so basically turn off the function itself and use computer voice (calls using the Internet).

How to turn off dial-in (web browser version)

  1. Go to the Zoom website and sign in
  2. Click “Settings” from the left menu on the My Account page
  3. Check “Computer Audio” in “Audio Type” from “Schedule Meeting” in the “Meeting” tab

In addition, when holding a Zoom meeting as a host, if the above setting is performed, dial-in by participants will also be turned off.

This is effective when you want to eliminate the risk of participants using dial-in by mistake and avoid the trouble of incurring call charges .

How to turn off dial-in (desktop app)

  1. Launch the desktop app and click “Settings (gear icon)” at the top right of the screen
  2. Click “Audio” from the left menu
  3. Check “Automatically connect audio on computer when connecting to meeting”

How to turn off dial-in (mobile app)

  1. Launch the mobile app and tap “Settings” at the bottom right of the screen
  2. Tap “Meeting”
  3. Tap “Auto Connect Audio” from “Audio”
  4. Check “Off”
  5. Tap “Done”

summary

summary

  • Dial-in settings are effective when participating in Zoom from a mobile phone or a smartphone with speed restrictions
  • Please note that using dial-in will incur call charges based on call duration.
  • If you can make calls over the Internet, it’s a good idea to turn off the dial-in setting

With Zoom’s paid plan, when making voice calls with overseas users, you can set the “premium audio” option so that the other party does not incur call charges.

If you add this option, you will be able to use toll-free voice calls, so if you have many opportunities to use Zoom with overseas branches and staff, please consider this option.
