Network and environment configuration

What this is: the minimum and recommended network and device settings for Visionflex virtual care.

Who it’s for: IT teams, network administrators and the person coordinating go-live. Send this link with the Email to your IT department template.

Bandwidth

Quality	Upload and download per session
Minimum	350 kbps each way (700 kbps total)
Default video (640 x 480 at 30 fps)	Above the minimum
HD (720p)	1.5 Mbps each way
Full HD (1080p)	3 to 5 Mbps per stream, and up to 6 Mbps upload if simulcast is used

Needs scale with the number of sessions running at once. Below the minimum, video quality and stability are unpredictable.

Ports

Port	Protocol	Purpose	Status
443	TCP	HTTPS for the Visionflex backend, RoomVu servers, WebRTC signalling, VF Sync and certificate checks	Required
3478	TCP and UDP	STUN and TURN NAT traversal (turnserveraus.visionflex.com)	Required
5349	TLS	Encrypted TURN fallback for restricted networks	Required
1935 or SRT	TCP	Camera streams for RoomVu (vfantmedia-prod.visionflex.com)	Required
1025 to 65535	UDP	WebRTC audio and video, avoids TURN relay	Recommended
80	TCP	Certificate validation (ocsp.godaddy.com, crl.godaddy.com)	Recommended

All connections start from the client. Ports 3478 and 5349 only accept traffic in response to an outbound request.

Allow outbound UDP. UDP favours speed over retransmission, which gives better audio and video than TCP.

Domains to allowlist

*.visionflex.com
*.tokbox.com
*.opentok.com
*.vonage.com
*.media.prod.tokbox.com
ocsp.godaddy.com
crl.godaddy.com

On the device

Local service. The Visionflex service uses localhost:5001. Don’t block loopback traffic.
Antivirus and EDR. Add an exclusion for the Visionflex install folder if needed.
USB. The GEIS camera, speakerphone and stethoscope must be recognised by the operating system. USB and endpoint policies must allow these device classes.
Bluetooth. Keep it on for the pulse oximeter, thermometer, ECG, scales, glucose meter and blood pressure monitor. Device management policies must not block pairing.

Pre-go-live checklist

TCP 443 open outbound
UDP allowed on 3478, and ideally 1025 to 65535
TCP/TLS 5349 open for TURN fallback
Visionflex and Vonage domains allowlisted
At least 700 kbps per session available
localhost:5001 reachable
Peripherals recognised by the operating system
Bluetooth on and devices paired
Antivirus or EDR exclusion applied

Test before clinical use

Run the Vonage pre-call test from each room where you will run consults. It checks WebSocket connectivity, TURN relay, media send and receive, and estimated bandwidth.
