Fleming video consultations use technology built on WebRTC, a framework that uses peer to peer (p2p) connections and MESH networking to enable a video call between a clinician and a patient.
We recommend that at a connection of least 2.0 Mbps outbound and 2.5 Mbps inbound or higher is used where possible.
For latency, please make sure you are experiencing less than 100 ms on your network. Up to 400 ms is acceptable, but not ideal for high-quality consultations. You can check your latency by running a Ping test or TraceRoute.
WiFi and Data Usage
Poor WiFi connections are the biggest cause of quality and connectivity problems. In many cases, the connection may be fast and stable enough at the modem, but a bad router or excessive traffic on the router can cause problems in the call.
If you're experiencing issues with echo, audio falling in/out or disconnects, try swapping to another network to rule out the possibility of a WiFi issue. Switching to a different router or trying an ethernet connection may resolve the issue.
If you are using via your smartphone to connect to the video consultation, on average this uses 5-8MB of data per minute.
Network Configuration & Security
If your organisation uses a firewall, you may experience some connection problems depending on your firewall settings. For a smooth experience, we recommend opening port 443 for outgoing traffic for both TCP and UDP. Additionally, outgoing traffic should preferably be direct and not sent through a proxy.
See the following article for more detailed information about firewall configuration:
Video Consultations: Firewall Configuration.
Right now we don't recommend using Fleming video consultations with a VPN. Not having a consistent IP address can cause problems connecting to a consultation. Our recommendation is to turn off your VPN for the video consultation, and then turn it back on after finishing.
You can use either:
- A desktop or laptop computer (which have a camera and headset)
- A personal smartphone
We designed our video consultations with ease of access in mind. The goal is to make it as easy as possible to invite people to the conversation, which is why it doesn't require any logins or downloads. This is done thanks to WebRTC, which can be built-in to most modern browsers. As this is a relatively new web technology, some browsers don't have full support for it yet, so to use the video consultation feature, your browser needs to support WebRTC (see below for a list of supported browsers).
Operating System Minimum Requirements
It is important that you can run the most recent version of our supported browsers. Below are the oldest operating systems that we can provide support for:
- Windows: Windows 7 and later
- Mac: MacOS 10.10 and later
- Linux: Any x64 based system
