I cannot participate in Circuit group calls
When I try to join a Circuit group call, the attempt fails after about five seconds.
This behavior was observed when the following conditions are true:
Your computer is on a corporate network that does not allow UDP traffic to be exchanged with the Internet.
- Circuit web client is used with Chrome and IPv6 is enabled.
Circuit web client is used with Internet Explorer and proxy settings are set to auto-detect.
At this time, the only alternative option to resolve the problem is to:
enable NAT routing of UDP traffic (at least selectively) between corporate network and Internet
in case of Internet Explorer usage, please set proxy manually instead of auto-detect.
We are working with Google on the IPv6 issue and fixing the problem in Internet Explorer plug-in for proxy. We expect a correction in an upcoming Chrome and IE plug-in release, but there is no a committed date for this yet.
The UDP addresses that must be reachable from the corporate network are:
for Europe: 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, 126.96.36.199 and 188.8.131.52 on UDP ports 3478 – 3485
for US: 184.108.40.206, 220.127.116.11, 18.104.22.168 and 22.214.171.124 on UDP ports 3478 – 3485
These are the addresses of the Circuit TURN servers.
