I have been trying to get the talk feature to work with Spark. I was on the previous stable build of spark, but upgraded to the Beta today and still am unable to get the jingle P2P talk function to work. When I’m in a conversation with someone, there is no phone button available. Both users have sound and microphone capabilities and both users have all software firewall protection turned off. Both users are also on the same LAN without anything interfering with the traffic that I can think of. Anyone have any suggestions?
