No VoIP/Jingle in Windows-Version

Hello Community,

I got Spark Version 2.5.8 running under Windows XP.

But I’m not able to see the Icon for making VoIP-Calls between two Jabber-Accounts.

am I doing something wrong or is this supportet in Mac-Version only?

Because the Screenshots in the online-Help are clearly showing this icon.

For testing-purposes I installed Jabbin and Spark and using two Accounts.

From jabbin I was able to call Spark, but not from Spark to jabbin.

Both are using the Jingle-Support.

So, what’s wrong?

Thx in advance for quick help.
