Using SIP or Skype for Business call: test@dial.vc (or click the link for a browser call) and you’ll be prompted to speak “1…2…3” and this recording will loop back to you. If you can see and hear this then you’re good to go.

If not, you can use the VC Connect firewall guide to ensure that you apply the correct settings to get video (and audio) working. Alternatively for Skype for Business users, please check this Support article if you are having issues: https://support.uci2i.com/hc/articles/115002058489
