How to synchronize jaber clients on PC and phone?

Question

Messengers

There is an openfire server. All users use the Pandion client.
There was a need to connect from a mobile phone. Used chatsecure and talkonaut.
When connecting from a mobile phone, the user is doubled. "user pandion" and "user mobile" appear in the contact list.
Can you do it with skype? So that messages are synchronized, and the user does not double up in the contact list of the interlocutor?
