Jingle client plug-in problem

Openfire Plugins
1

I am very new to Spark, but am really impressed.

Just one small issue - probably because I do not understand properly!

I installed the Jingle Client plug-in and it worked fine for me straight away.

Two of my friends did the same. I can call them and we can speak with no problem.

But only I have the telephone handset icon on the chat page - they do not.

So I can make outgoing calls, but they cannot.

Can anyone help please?

This is also my problem. Sometimes both sides have the Call button, sometimes only one side can make the Request. I still have no explained for this Can any pro help us to clear this problem?
