Voice and video calls on KollabiuM

On KollabiuM, you can call someone right from a private chat with the "Call" button in the chat header, by voice or video, with no phone number or third-party apps needed. Video calls are available starting with the Y plan. It comes in handy when a conversation has been going back and forth for a while and it's simply easier to talk it through.

How to make a voice or video call?

1. Open your private chat with the person.
2. Tap the "Call" phone icon in the chat header.

You'll see "Calling…", then "Connecting…", and finally "Connected" once the other person picks up.

You can call someone as long as you're both able to message each other. If the person has restricted messages from you or blocked you, calling won't be available.

What depends on your plan

• One-on-one calls: voice calls on the X plan; voice and video calls starting with the Y plan.
• Group calls in a group chat: up to 3 people starting with the Y plan, up to 5 on Z, and up to 20 on Alpha plans.

Learn more on the "Tariffs" page, in the "Calls and conferences" section.

Incoming calls

When someone calls you, a window with their name and profile picture pops up over whatever page you're on, with "Answer" and "Decline" buttons. If the site is closed, you'll get an "Incoming call" push notification. Tap it to answer.

If you don't answer within about 30 seconds, the call ends, and you'll get a "Missed call from …" notification.

During a call

• "Mute microphone" / "Unmute microphone".
• "Speaker": choose where the sound goes, such as headphones or speakers. This button appears if your device has more than one audio output. On iPhone, audio is switched through the system controls.
• "End call": hang up.
• Connection quality: shown at the top as "Excellent connection", "Unstable connection", or "Poor connection".

You can go back to the chat with "Back to chat" without ending the call. A "Return to call" bar will appear at the bottom.

Call history

Calls are saved in the conversation as "Outgoing call · 0:38", "Incoming call · 0:38", or "Missed call". Tap one of these messages to call back.

Why a call isn't working

• "Allow microphone access": your browser didn't get access to the microphone. Allow it in your browser settings. In Safari on iPhone, go to "Settings" → "Apps" → "Safari" → "Microphone" → "Allow".
• "Your microphone is busy in another tab or app": close the other call or the app that's using the microphone, then tap "Retry".
• "Play audio": your browser blocked the sound. Tap the button.
• "This person is busy": they're already on another call. Try again later.
• "Connection lost": tap "Call again".
