3. System requirements
Physitrack Telehealth has been designed to work in a wide range of browsers and on a wide range of iOS and Android devices.
That said, because security and privacy are paramount to Physitrack, we limit support to reasonably recent browsers and devices that still fall under their publisher's patching support.
Have a look at the requirements below, or skip to the next section (Workflow).

Firewall settings
- For video calling (Voxeet)
- To make sure we go through firewalls, we automatically switch from User Datagram Protocol (UDP) to Transmission Control Protocol (TCP; HTTPS).
- If you are having a firewall problem, use the 443 port---this often solves the problem. If it does not solve the problem, please contact us.
- Currently, video calling does not go through China's firewall system.
- For presence detection (Google Firebase)
- Open ports 5228, 5229, 5230 for Firebase communication.
- Open communication at proxy level between the source server and following URLs:
fcm.googleapis.com
gcm-http.googleapis.com
accounts.google.com
