Hi All,

I get the following error when I initiate desktop sharing with another user we both are connected from outside the corp network.

The same is not working from an internal to external and external to Internal uses as well.

Does Desktopsharing work on internal network? Both users from the same Organisation?

Hi channavera,

Does Audio/Video work ?
