Openfire zoiper


I want to do instant messaging with openfire and Zoiper as openfire is a XMPP server and Zoiper is a XMPP client.

So I added in Zoiper an XMPP account with the same JID declared in openfire (as user).

But the problem is I can not make the chat unless the spark is connected with the same user account.Also when I wrote a msg on Zoiper, it came on spark not Zoiper.

I don’t know how I should do (configuration or something else) to not chat through spark and connect directly to openfire.

Please any ideas and thank you in advance.
