Running the audio / video service requires the Browser to access the audio / video chat services on the internet over specific ports in order to work.
The audio / video chat service uses the following domains:
The following HTTPS verification servers must be accessible for SSL certificate verification:
The minimal Requirement is that TCP port 443 is open. Some firewall/proxy rules only allow for SSL traffic over port 443. You will need to make sure that non-web traffic can also pass over this port.
In addition to the minimal requirements being met, we also recommend that UDP port 3478 is open. The User Datagram Protocol (UDP) favours low latency over error-correction and is well-suited to audio and video communications.
Port 3478 only accepts inbound traffic after an outbound request is sent. The connection is bidirectional but is always initiated from the corporate network/client so it is not possible for an external entity to send malicious traffic in the opposite direction.
For the best possible experience, we recommend that UDP ports 1025 - 65535 be open.
You can test if a network meets the connectivity requirements by using the OpenTok Connectivity Doctor: http://www.tokbox.com/tools/connectivity/ (you must use Chrome).
Video: 300 kbps per stream (recommended lowest level)
Audio: 50 kbps per stream (recommended lowest level)
The Collaboration Server must be able to communicate with https://api.opentok.com/ which is a service located on the Internet. Thus, port 443 must be open for outbound traffic to api.opentok.com.
