Video calls stutter as soon as the laptop is on VPN

A full-tunnel VPN routes video traffic over your VPN gateway, adding latency and packet loss. For Teams or Zoom, enable split tunnel, otherwise it stays bad.

Try this first

  1. 1Check the VPN config, full tunnel means everything goes via the gateway, including video calls.
  2. 2Configure split tunnel so Microsoft 365, Zoom and Google Meet endpoints bypass the VPN, Microsoft explicitly recommends this.
  3. 3For Zoom, there is a list of Zoom IPs you can exclude in VPN config, ask the vendor.
  4. 4Test impact, a speed test alone says little, use a meeting with screen share and mic open.
  5. 5For rooms always at the office, you do not need to run VPN on the room system, that is a design choice.
  6. 6Document which clients fall under which VPN policy, otherwise users see different behaviour per profile.

When to bring us in

Across multiple sites or many remote workers, split-tunnel policy is a standard piece. Vectel can configure it on the VPN firewall.
