Highfive does not interoperate with other video conferencing solutions.
Most existing VC systems were built on older architecture which require on-premise or hosted bridging systems to enable interoperability. In addition, Highfive's technology is proprietary and does not work with the H.323 (video) and H.239 (screensharing) standards that traditional systems tend to use.
Instead, we’re focused on making it simple to connect from any Internet connected device (i.e. all major browsers, iOS, and Android).
