It is possible that you are behind a high security firewall that is blocking our video service. Please go to http://tokbox.com/tools/connectivity/ and verify that all tests can pass on your internet connection. If one or more tests fail, you are being blocked by a firewall.
The first section of the Pre-call test checks for Hardware (Audio/Video) and Software (Browser compatibility). The second section tests for connectivity - whether or not you are blocked by internal firewalls. Four green ticks means you are all good and have no firewall blockers. The third section checks for your expected call quality. Ideally, you want to see Video and Audio quality as Excellent. If any of the sections indicate you are not set up correctly, get in touch with us at firstname.lastname@example.org and we will be happy to help.
For your current meeting we recommend switching to a 3G/4G hotspot from your smartphone. After your meeting is complete, please pass the following request to your company's IT department to allow the following ports through:
Open port 443 to allow SSL traffic
Open UDP port 3478
If the UDP ports are not available the traffic will go via TCP 443 HTTPS/WSS and your meeting can continue as normal
