Voice chat icon doesn't appear

Hi,

I’ve downloaded the last spark release, but can’t make a voice chat with another user. I tried it between Windows machines and the button to make a voice chat just doesn’t appear.

What I’m doing wrong?

thanks in advanced…

regards,

anyone with a hint on this?

we already enabled the “Media Proxy Settings” (not sure if we really need this for voice chat support) on OpenFire

Our configuration is just local so, I really don’t know what else we must enable on the server.

I tried with the “cocinella” client, and the voice chat support worked ok throug openfire server, so I guess this must be a spark issue…

regards,
