Voice calls

Hi. I have openfire server (3.7.1) in the local net (no internet access) and users have spark client (2.6.3) their machines.

I want to make a voice call but there is no appropriate button

Is there something i should activate on client or server?

Thanks for quick answers!

I’ve found it here:http://community.igniterealtime.org/thread/44418

Short version:

-jingle plugin requires STUN server

-if you don’t have one (isolated net) insert fake STUN server name in the Spark options windows
