About
Kaltura's Agentic Avatars use WebRTC technology to enable real-time, interactive conversations.
In some enterprise environments, firewalls, proxies, web filtering, or other network security policies can affect the connection. Browser and microphone permissions can also affect the experience.
This article outlines the browser, internet connection, and network requirements for using Agentic Avatars.
Browser and device requirements
Agentic Avatars are tested on the following browsers:
- Windows: Google Chrome, Microsoft Edge, Mozilla Firefox
- macOS: Google Chrome, Safari
- iOS: Safari
- Android: Google Chrome
Microphone permissions
To speak with an Agentic Avatar, you must allow microphone access for your browser. Microphone access must be enabled in both your operating system and browser settings.
If microphone access is blocked, you can still interact with the avatar using text chat.
Internet connection
Use a stable internet connection for the best experience. Agentic Avatars are tested on corporate networks, Wi-Fi connections, and 4G and 5G mobile networks.
Agentic Avatars use WebRTC for real-time audio and video and WebSocket connections for communication with the service.
Bandwidth requirements
Because conversational avatars stream real-time synthesized video and bi-directional audio via WebRTC, a stable broadband connection is required:
- Downlink (Avatar Video & Audio Stream):
- Recommended: 1.5 – 3.0 Mbps dedicated download speed per active avatar session.
- Minimum: 1.0 Mbps (video may downscale or adapt frame rate under network pressure).
- Uplink (User Voice / Microphone Input):
- Recommended: 100 – 150 kbps (standard Opus / WebRTC audio stream for real-time ASR).
Corporate network requirements
If your organization uses firewalls, proxies, web filtering, or other network security controls, work with your IT or security team to allow the required domains, ports, and protocols listed below.
| Domain | Port | Protocol |
|---|---|---|
| conversation.avatar.us.kaltura.ai | 443 | HTTPS / WebSocket |
| api.avatar.us.kaltura.ai | 443 | HTTPS |
| flow-assets.avatar.us.kaltura.ai | 443 | HTTPS |
| meet.avatar.us.kaltura.ai | 443 | HTTPS |
| studio.avatar.us.kaltura.ai | 443 | HTTPS |
| rtc.avatar.us.kaltura.ai | 443 | HTTPS / WebSocket |
| assets.avatar.us.kaltura.ai | 443 | HTTPS |
| turn.avatar.us.kaltura.ai AND 3.41.177.176/29 | 80, 443 | TCP / UDP / TLS |
Troubleshoot connection issues
If you experience problems connecting to or interacting with an Agentic Avatar:
- Make sure your browser has permission to use your microphone.
- Make sure microphone access is enabled in your operating system settings.
- Try connecting from a non-corporate network or a 4G or 5G mobile connection. If the avatar works on another network, your corporate network settings may be blocking a required connection.
- If you use a corporate network, ask your IT or security team to verify that the required domains, ports, and protocols listed above are allowed.
