I am trying to get VOIP to work on Windows Server 2008. We have OpenFire running as the XMPP server, this is running on a Linux PC, Spark is running on the Windows PCs.
Using Spark 2.5.8 the voice connection is made and operates once, but to make a follow on call I have to logout and then log back in. I have tried Spark 2.6.0 beta 2 but this fails to make any connections.
Has anybody experienced this problem and overcome it.
