Sonant Voice Conferencing

Sonant Voice Conferencing

Page last updated 4/21/20

Sonant is used for voice conferencing. Two versions are provided in the download. The “old” version is represented by a green icon, and the “new” version is blue.

Please review the security reminders prior to use, especially if you use Windows XP. Windows XP is no longer supported by Microsoft and should no longer be used. Security updates are no longer provided, making Windows XP a significant risk.

Windows 7 is also obsolete and Microsoft no longer provides security updates for it. Therefore you should no longer use Windows 7.

The only supported version of Windows is Windows 10. Do not use older versions of Windows.

The majority of Sonant servers require using the “new” version (blue icon).

After installing Sonant you will see two Sonant icons:

  1. Blue icon (v1.2.3)- For use with newly updated Sonant servers. Use if your project coordinator indicates this is necessary.
  2. Green icon (v1.1.8) – Use to connect to your existing Sonant conferences.

Download Sonant



Install Sonant

Windows: First, uninstall the old Sonant program. Next, double-click the newly downloaded program, and follow the installation wizard.

Mac: Delete any existing Sonant icon from your Applications folder. Also, drag the Sonant icon off of your dock. Now double-click the newly downloaded Sonant file. Drag both the Green and the Blue icons into your Applications folder.

Run Sonant for the First Time

Sonant leads you through a setup wizard the first time you run it. Please read each screen carefully, and adjust the sliders as instructed. Pay special attention to the following:

– Check mark “Enable echo cancellation”
– Un-check “Enable positional audio”
– Specify a “Push-to-Talk” key –> Click in this field, then tap the Control key. Then continue on from this screen.

Set Push-to-Talk Key

After installing Sonant, make sure your Push-to-Talk key works. To do this, log in to a Sonant server, and double-click a room name to enter a room. Make sure you are not muted (no mute flag appears in Sonant window). Now press your Control key (which was set as your Push-to-Talk key in the last step). The lips next to your name should turn red as you hold down the Control key. If not, follow these instructions:

Blue and Green versions: Press: Configure–>Settings–>Shortcuts (On Mac computers press: Sonant–>Preferences–>Shortcuts)

  • Look for the shortcut as in the image below. If it does not appear, click Add.
  • Now click on the word “Unassigned” which just appeared to display the drop-down menu.
  • Select “Push-to-Talk” from this drop down menu.
  • Now click just below the “Shortcut” column heading (you’ll see the words “Press Shortcut” appear)
  • Now tap your Control key. The “Shortcut” field should now say “Control,” just like the image below.
  • Press OK to finish.

Green version difference: After clicking the Control key, the “Shortcut” field will say “K:Ctrl” (on Windows computers) when properly set.

Note: If there are two shortcuts, delete one of them (use the “Remove” button). After setting the key properly, the screen should look like this:

Connect to Server

When you run Blue Sonant, you will see a list of servers. This list will be blank the first time you run it. You will need to add a server to get started.

Press “Add New…” and fill in the details as shown in the image below.

Note: The password prompt does not appear when you add a server. You will be prompted for the password after you press CONNECT.

  • Enter the info, similar to what is shown below
  • Note: Some Sonant servers do not allow SPACES in your “Username”
    • John-NY <– valid
    • John_Anderson <– valid
    • John Anderson <– not valid
    • If you see a “Invalid username” prompt when you try to connect, you may enter a name without spaces and connect, but the new name will NOT be permanent.
    • To change your user name, or make your username permanent (necessary if you had an invalid name, even if you corrected it while logging in). Follow these steps to change your username so you won’t get an “invalid username” error every time you connect:
      • Go back to the server list
      • Right-click on the server name
      • Select “Edit” (you will see a window like the one shown below)
      • Type in a valid username, with no spaces
      • Press OK
  • When you press CONNECT the first time, you will then be prompted for the password (you will see an invalid password error after you press CONNECT). Enter the password provided by your Sonant administrator. It will be saved, and you will not need to enter it again.


  • The first time you connect, you will see a security certificate warning. Click OK or Yes. It will not re-appear.
  • Adjust the window size and column widths so you can see the Name and Flags columns (only necessary on Green version).

Using Sonant for Conferences

After the initial installation and configuration use Sonant as follows:

  1. Load Sonant
  2. If the server list isn’t visible, press SERVER, CONNECT
  3. Click on the desired server, then click CONNECT
  4. To speak, simply hold down the Ctrl key and talk. The “lips” icon next to your name will turn RED while you’re speaking
  5. Note: Watch the left-side of the window for messages sent during a conference.
  6. Make sure your mic is not too close to your mouth. It should be level with your mouth, but positioned away to avoid breath noise.

When you temporarily leave, press the Mic button: Mic mute to mute yourself (or press Audio > Mute). This puts an icon next to your name that shows others that you’re not there (or that you’re not back from SFRT), and they will know to skip you during the reading or discussion.

If you have any questions, please leave a comment below.



MacOS 10.14 “Mojave”

Apple’s Mac operating system, MacOS Mojave, which was released on September 24, 2018, adds some security features that may prevent Sonant from working properly. The “lips” may not turn red next to your name when the mic is activated, and/or the microphone may not function. These issues can be fixed by doing the following:

  1. Run Sonant (click “Allow” if asked, etc.)
  2. Run MacOS System Preferences
  3. Click on  Security & Privacy > Privacy > Accessibility
    1. At the bottom, left of this window, look for a padlock icon. If it appears “locked,” click it, and enter your Mac’s login password to unlock it.
    2. Checkmark Sonant
  4. In the left-side column of this same window, click on “Microphone” and checkmark Sonant.
  5. Close and restart Sonant

If the Sonant icon is not visible on either of these screens, click the “+” button, then navigate to the Applications folder, select Sonant (blue icon), and click “Open.” Now checkmark Sonant as described above.


Using an iPhone / iPad to Connect

An iPad or iPhone can be used to connect to some Sonant servers. The app “Mumble” (by Mikkel Krautz) works well (

There are some issues to consider however. Please note:

  • The Sonant server you wish to connect to must be configured to allow iPhone access. Contact your Sonant server administrator if you are unable to connect.
  • In Mumble, add your Sonant server info in “Favorite Servers.” Click “+” to add the new entry.
  • Before connecting, on the Mumble screen click in the upper left: Mumble > Preferences > Transmission, and select “Push-to-talk.” Do NOT use voice-activated or continuous. Use “Push-to-talk.”
  • Click “Trust Certificate” when prompted when you log in for the first time.
  • If you see errors, like certificate errors, use a username that is slightly different from the name you use on your other computer (contact your server administrator if this doesn’t work) (there is a way to use the same name, if you export your certificate, then import it in Mumble, but that’s beyond the scope of these instructions).
  • Hold the large lips icon to talk
  • Always use headphones (on PC, Mac, and iPhone, etc.) as consideration to others, to prevent annoying loud echo when more than one person speaks at the same time.
  • If you are not participating, mute yourself by clicking the three-line icon on the upper-right corner in the Mumble app, and click “Self-mute.” This will let others know you aren’t participating.

  1. Hi I am a young practitioner I use sonant to study the fa but for some reason the top and side has dissapeared so I can’t talk or text to my other fellow practitioners I glicthed can you help?

    • If you’re using Windows, try one of these options. Depending on your exact problem, one of these steps might solve it:
      1. If all you see is a plain window, right-click in it, then select Configure, and unselect “Minimal View.”
      2. Right-click in the drop-down menu area of the Sonant window. Be sure all three selections are checkmarked.
      3. Hover your mouse very slowly around the Sonant window edges, watching for the words “Drag here” to appear. Then drag the window segments around to reposition them.

  2. Hi I have been missing some Fa studies. Sonant sometimes doesn’t work. I try to add new label and address and fallowed your instruction. When I click connect after I put the information nothing happens it doesn’t even ask for password. Only the first address that I put after I downloaded is working. But it doesn’t let me put the new one. I think I tried everything I don’t know what I am missing. Thank you!

    • To add an additional server, press the “Add New…” button and fill in the information. A new entry should appear in the connection window. If you cannot connect, check the settings (address, port, etc.). If it still doesn’t work, check with the server administrator. It could be that the server hasn’t been updated, and requires that you use the “green” Sonant program.

    • The label is just the name you see in Sonant’s list of connections. Type whatever you want in the label field to identify the conference, and differentiate it from others you may have. Please compare it to your existing connection (right-click and select “Edit” to change these fields on existing connections) Please see the example above in the “Connect to server” section.

  3. We study fa on Sonant. Is there any way I can set up to press a key once to start to read, and then press the key again to stop after finish reading? Some senior practitioners found it was hard for them to read while have to keep one hand to hold down the Ctrl key. Thank you!

    • Sonant can be set so that a double-tap on the mic key will lock the mic on, so you won’t have to hold down the button continuously. You can tap it once to stop talking.
      In Sonant settings, checkmark the “Advanced” box, then click “Audio Input.” You’ll see a slider labeled “DoublePush Time.” Slide this to about 500ms (about half way up). Click OK.

  4. when i download the sonant for mac os x, there is a message pop up: “” can’t be opened because it is from an unidentified developer.

    so how can i use it on my macbook air

    • Right-click on the application and select “Open.” Then press OK or Open at the next warning window. From then on you should be able to open Sonant without any errors.

  5. Hi, the computer has Sonant runs very slow, so I installed Sonant — 1.2.3 to a new computer (Acer Aspire IV5) following your instruction, but it says “wrong sever password for unregistered user account, please try again.” I tried “add new…” with a different Username, same problem. Could you help? Thank you very much! Michele in USA

    • The first time you connect with any server, there is no password entry area. But when you press “Connect” you will see the “wrong password” prompt. At this point you should enter the password.

      Usually the username doesn’t matter, but that depends on the server. Just be sure you know the correct password before starting. If you enter the password incorrectly multiple times, the server may lock you out for a few minutes. In that case try again later.

  6. I have read all the comments above, I do think that I need a help from you. I installed sonant at my home, tried mac and windows 7, no one works. During installed every thing looks ok, but when I connect to the server, it always shows ‘time out, failed.’ Then I try to install it in another mac at my work place, it just cost 5 min. it works. But I can not use sonant at my work place. So please help me what is wrong, and what could be the problem when I installed at my home.

    • First, make sure you are using the same “color” of Sonant at home as you are at work. Most servers now require the “Blue” Sonant, but some still use the green.

      If you’re using the same color Sonant icon at home and at work, and since both Windows and Mac computers can’t connect from home, the problem may be your home router settings or Internet connection. Check those settings. Also check the firewall settings on each computer to make sure that Sonant is allowed.

      Normally you shouldn’t have to change any of these things to run Sonant, but the settings are different in different versions of the operating systems, and someone may have changed some settings on the computers or router.

  7. 1. I am using the blue icon one on Mac Mini. After Apple upgraded the OS to Mojave, the push-to-talk shortcut couldn’t be assigned although it was working fine before the system upgrade. What could be possible reason for this issue? By the way, is there an update button in Sonant App?

    2. Again after upgrading to Mojave, when I started other App while Sonant is on, a pop-up window shows that ‘Sonant tries to gain access to the App’. It happened to a few Apps I tried to open at that time. It never appeared before the OS system upgrade. What could be possible reason?

    Thank you!

  8. Hi, it seems that Sonant is not responding when I set a shortcut key for a function such as “Push to talk” (in “preferences” section). How to fix this problem? It happened just after my Macbook updated its driver.

  9. Hello, I installed latest Sonant version on my Mac Mojave 10.14.4 but it keeps warning me as bellow every time I open Sonant:

    “Sonant has detected that it is unable to receive Global Shortcut events when it is in the background.

    This is because the Universal Access feature called ‘Enable access for assistive devices’ is currently disabled.

    Please enable this setting and continue when done.”

    When tap on ‘enable this settings’ it brings me to Accessibility settings but I’ve followed the instructions for installation on Mac Mojave as above.

    The ‘push-to-talk’ sometimes doesnt work.

    Please help on my case. Thanks.

    • The global shortcut warning can be ignored. Just click OK or press Return. That dialog appears because Sonant hasn’t been optimized for the last few MacOS updates.

      For the push to talk problem, go to Sonant Preferences > Shortcuts and remove the current key, and add the Control key as your push to talk key. See the instructions above. NOTE: Make sure you have only ONE key set for push to talk. Using keys other than Control may not work properly.

      Also, be sure to follow the instructions above for MacOS Mojave. Sonant won’t work properly unless you make these adjustments.

  10. Do you have a system with iped pro? Every time I go to a different country or a different place, it is convenient to bring iped, but I can’t install it successfully if I try to install it. The system does not match.

  11. hello. do you have an app for iPhone/iPhad? Mumble works on Android tablets and phones, but for iPhone/iPad a certificate is missing. may you have a solution or an advise how to get it? thank you!

    • Try using a different username, or alternatively, export your existing certificate from Sonant on your computer and import it into Mumble. For specifics, please see the iPhone how-to info recently added above.

      • hello, i tried the description with slightly different username, also importing the existing user certificate from sonant macosx but neither worked. always got the message “Connection Rejected…No reason”. In the server list i could add the sonant server and also the stats [connection speed / people online] are visible and working. But connecting to the sonant-server for listening/speaking is not working.
        I tried to connect to public servers, to verify if mumble on iphone will work in general in my case and there was no issue.
        It is said above to contact server admin in case of error: what he can do in such cases? Do you have a sonant server as example connecting with iphone to it is working? Thanks in advance…

        • If you were able to connect to this exact server using Mumble on Android, then it seems like your iPhone should connect too, by using a different username. But the admin could be blocking unknown client software, allowing only known users, requiring certificates, etc.

  12. Hi facing below error please help me
    Server connection rejected: Administrator user on your PC is not allowed to connect.

    • The error means that you are logged in to your computer using an account with administrator privileges… I haven’t see this error since Windows XP was in use. Are you using Windows XP by any chance?

  13. Hello! I still have an issue on my iPhone with Mumble. It still says Connection Rejected No reason. I added the certification from iTunes but still it doesn’t connect.

  14. I am a practitioner from Australia, My apple mini and apple desktop both can not set up the key of push-to -talk, I found there are similar cases among us, can you suggest how to solve it.

    Also when I use Mumble in iPhone , we found my name in the sequence of the group lists is different with other system, for example apple mini which is the same with other practitioners computers, if will effect us when we study Fa together, can you suggest how could we make the screen lists is the same.

    • Not all keys can be used for push to talk. Try using the Control key(s) for that. I’ve never had a problem using the control keys for push to talk.

      If you’re using a third-party keyboard, it’s possible that could be the reason it’s not working, maybe due to the key mapping system used on the keyboard. Try another keyboard, or an Apple keyboard.

  15. Hello,
    someone asked me what that green symbol means. When you go with your mouse cursor over it it says the user is “authenticated”. Its right next to your name where for instance also your mouth is placed when you are set on mute.
    So yes, what does it mean and how to add or remove it?

    • That symbol indicates that the user is “registered.” This is used for secure authentication, where instead of a password, each user has an embedded, encrypted certificate which proves they are who they claim to be.

      Practitioners typically don’t use registered user accounts, so you normally shouldn’t see a green symbol. They instead log in with whatever name they choose, and everyone uses the same, shared password.

      These symbols may start appearing next to your name if you have clicked “Register” on the “Self” menu for some reason. There’s no point in doing that as it will confuse people and could make logging in on a different computer no longer work. You may be able to “unregister” from the Self menu to undo it.
      EDIT: You’ll need to contact the system administrator to unregister a user.

      • Hello, thank you so much for the quick reply. I tried to get him “unregistered”. But there is no button for that. I now could find the “self” and “register” field. Since I’m not registered myself I can see that field. In his case, since he is registered already, that field is grayed out and he cannot change anything. You are right, that symbol really confuses others and there is no need to register, also because it can generate problems in logging in to other computers. Can you tell me the “unregister” procedure?
        Thank you very much again.

  16. Hi, Sonant doesn’t work with my headset, no sound, no mic. The headset works fine with all other apps I have, though.
    I installed an AISO driver for the sound card instead of the normal Win sound driver, maybe this is the problem? Does Sonant work with AISO drivers?

    • I have no idea. I use a Mac, where driver problems aren’t an issue. All I can say is, plug in your headset before starting Sonant, not after.

  17. May I suggest you use new servers or new software for conferencing.

    From my understanding, Sonant has not had any updates since 2012 making it very obsolete. <– as you can see.

    I could not install Sonant for my wife who is a practitioner, because we use Linux for security reasons and the linux versions are also more than 8 years old now.

    You cannot use regular Mumble to connect, because Mumble now cannot communicate with the old code base of Sonant which is outdated and now insecure.

    I would suggest a Mumble server, or to make it easy for new practitioners, setting up a Discord server which is completely free for server admins and would not even require hosting on your part.

    • The Mumble clients for Windows, Mac, iPhone, and android work fine with both Sonant server and Mumble server. If it doesn’t work with Linux, well, I doubt it’s the only incompatibility you’ve encountered. I recommend using a Mac for the best mix of compatibility, ease of use, and security. To resolve the connection issue, maybe ask the admin of the server you use to switch to Mumble server?

  18. Hi, I have a problem with Sonant recently. There is no single letters or numbers or anything appearing but a completely blank box when I log in. I can’t choose the room, can’t see anyone’s name etc. My laptop is MacBook Pro. I downloaded Sonant a few months ago, and have been using it fine till recently. And the box saying “Sonant quit unexpectedly” keeps turning up and sending report to Apply. Can you please advise me what to solve this problem?

    • Depending on your exact problem, one of these steps might solve it:
      1. If all you see is a plain window, click Configure in the top menu bar, and unselect “Minimal View.”
      2. Hover your mouse very slowly around the Sonant window edges, watching for the words “Drag here” to appear. Then drag the window segments around to reposition them.
      3. As a last resort, go to Sonant preferences > User Interface and click “Restore Defaults.”

  19. Hi, I’m using Macbook Pro, OS10.15.5.
    Push to talk used to work, but after recovering from the backup, I cannot use it anymore. Though I’ve already allowed sonant in Universal Assess.
    Please help. Thank your very much.

    • The obvious place to start is recreating the shortcut for push to talk. What happened when you tried that? If you’re not able to change the shortcut, quit Sonant, then go to System Preferences > Privacy & Security > Accessibility, and UNCHECK Sonant then RE-checkmark it. Then re-set the shortcut. Use the control key for PTT.

      • Thank you for the reply. I cannot recreate the shortcut for push to talk as it doesn’t respond to any key. I’ve also unchecked and rec-checkmarked Sonant in System Preferences > Privacy & Security > Accessibility. Still not work.

        • There’s another method that might work for you.
          First, quit Sonant. Then right-click on the Sonant app in the “Finder” (in the Applications folder) then click “Show package contents.” Navigate into Contents/MacOS then launch Sonant by clicking on the Sonant executable file in that folder. This opens Sonant using Terminal. You may be prompted to add permissions, which you should do. You may then able to add shortcuts.

          Another thing to consider is using Mumble. It’s what Sonant was based on, looks almost identical, but unlike Sonant it has been updated over the years. In Mumble, there’s a way to eliminate all those reminder messages you see every time you start an app. (Hint: To do that, enable overlay, save, restart the app, then disable overlay. <– Works in Mumble only, not Sonant)

          I hope this helps!
