Hi Fernando,
Your first steps should be to investigate logs on both sides first - CRM_ICI_TRACE in SAP CRM and VU Integration OII log in SAP CCtr.
Nevertheless, from the very few symptoms you have described it seems that CRM is able to communicate to CCtr, but CCtr is not talking to CRM.
This has been discussed in this forum several times and there can be different reasons for this.
I assume this from your screenshot, where you see success message. This is based on positive response from CCtr, invoked by CRM request.
However, user status is sent from CCtr to CRM and apparently, this message is missing.
First please check if there are any firewalls between CCtr and CRM. Also remember, that the connection CCtr->CRM is initiated from OII VU address, not from CCtr server physical address.
But most often I see root cause that the service users, under which is running OII, has in its profile set company proxy. In most times, the proxies is unable to reach internal SAP servers, therefore cannot propagate SOAP requests from CCtr to CRM.
Quickest test is as follows:
1) logon to the CCtr application server, where you VU Integration is currently running, under the service user, which runs the Web Application (can be different from HAC and other users!).
2) open Internet Explorer, go to menu Internet Options, tab Connection, click button Local Area network settings. Alternatively, reach the setting from Control Panels.
3) Do you see in the popup checked checkbox Use Proxy? If yes, uncheck it and save settings.
If not, come back here :-)...
4) If you have unchecked proxy, quickly try to logon to CRM UI. Why quickly? Depending on your AD settings, the service user profile will get refreshed and set the proxy back again.
If this is the cause, check symptom 11 on this very useful wiki page SCC- Common Errors and what they mean - Online Interaction Interface (OII) - CRM - SCN Wiki by Lloyd Goveia.
Hope this helps.

Dawood.
