Presence Indicator is not working

Hi All,

I am trying to open SharePoint 2013 site within client servers.

Microsoft office communicator 2005 and outlook 2010 are installed in the server wherein I am trying to open the site.

Name.dll presents under "C:\Program Files\Microsoft Office\Office 15" location.

Users mail address is the SIP Address of the users in AD.

But people presence is not indicated in Sharepoint 2013 pages and people results of sharepoint 2013 search.

Tried with the below suggestion as well,

Disabled and Enabled "Additional actions and online status for members" in CA

But no luck:(

Please advice me on this.

Thanks in advance!!!
