First use

What can I do with Sylaps?

With Sylaps, you can talk on audio/video conference and chat with people for free. You can also share your screen, exchange files and invite your existing contacts from across social networks to join the meeting.

No, you don’t need to install anything. We developed Sylaps to be accessible from your browser. We built an app for every platform that you can install to ensure a full Sylaps experience.

Does it cost anything?

Sylaps is free to use: just meet people you want and start a meeting, now.

Is it required to create an account?

You do not need to open an account or provide your email to make it work. Simply start a meeting with one click.

How many people can join a room?

Sylaps is not putting any limit on the number of users in the room.

However, there is certainly a limit in terms of user internet bandwidth. We do not recommend having more than 8 users sharing video/audio at the same time for performance and quality reasons.

How do I get contacts?

When you start a meeting, or are in a room, (in the tab Invite) you can connect your social networks and get all your contacts in a list.

How do I invite people to talk in a room?

There are different ways to invite people in your room. The easiest way is to click on the invite tab and type an email adress or a phone number (with dialing code) and press invite. Or you can simply click on the link icon and copy the room url and paste it where you want (an email, a direct message on twitter, facebook, etc.).

Can I send a text to invite people in a room?

In the invite tab, you can type a phone number (with the dialing code, for example: +33 for France) and invite people by text. They'll get a message with your room link and just have to click on it to start a meeting with you.

How do I mute the sound from other people in the room?

On each participant in your room you have 3 buttons on the right bottom. The middle one disables or enables sound of the participant.

How do I mute my own audio?

To mute your own audio, use the microphone button on the top bar.

How do I send files to people in the room?

To send files to people in your room, click on the Files tab. Click on browse storage or drag and drop files on it and press the share button.

How do I share my screen?

To share your screen use the "Start screen share" button on the top bar. The share screen feature works only on Google Chrome, Firefox and our native desktop apps.

Why do I have to install an extension to share my screen?

The share screen feature requires an extension due to a Chrome API restriction. When you activate it the first time, you'll have to install the Sylaps share screen extension, and a few seconds later you'll be able to share a specific window or your entire screen.

How do I lock my room?

To lock a room you first need to authenticate and then own the room by creating it or claim an existing one that is not owned by any user already.

Once you own the room, the "Lock Room" button (in the top bar) allows you to lock and unlock your room.
When your room is loocked, no new participant can enter in your room.

What is "Start vocal assistant"?

Simply click on the "start vocal assistant" button and you'll hear a welcome voice. Vocal assistant will read all notifications and messages for you. It will also execute voice commands like "OKAY, share screen" to share your screen for example.

Can I make the room take up the entire screen?

Yes, click on the "Go full screen" button next to the "Leave Room" button in the top bar and this will initiate a full screen session.

How do I leave a room?

That's really simple, close the window / tab browser or click on the red "Leave Room" button in the top bar.

Which ports in my firewall have to be open to work with Sylaps?

What is the primary technology that powers Sylaps?

Sylaps uses WebRTC, a Web Real-Time Communication API generaly available in modern browsers.

For more information:

  • Webrtc.org
  • Wikipedia - WebRTC
  • Youtube - What is WebRTC?

Does video call or audio call (WebRTC) work with TorBrowser?

Tor Browser is built without WebRTC support, since WebRTC can be used to circumvent Tor's proxy settings via ICE over UDP. In Firefox, WebRTC support is controlled by "media.peerconnection.enabled" preference, and it's set to false by default in Tor Browser. But, even enabling this preference would not turn WebRTC on, since the Firefox binary does not contain the functionality.
