Querying the Presence of the User
![qa-featured](https://www.techyv.com/sites/default/users/superadmin/qa-featured-300x270.png)
After establishing the Data Channels in AJAX, I used it in querying the Presence of the User. When the session is already initialized, querying the Presence of the User sends a request to the Communicator Web Access Server through command channel. My problem is, the connection cannot be established. It times out and shows nothing. What do I need to fix this? Can someone please help me?
