Our phone system has a desktop agent that can shell out or communicate with external applications.   We have an existing application that gets account information through web services, then invokes an instance of internet explorer 6 and directs the browser to the appropriate account.  

I am performing maintenance on this application, and I'm trying to figure out how to have the application log into the SalesForce web application.   I am successfully logging in through the web service, but the web application is requiring me to log in again when I attempt to navigate to the account page. 

Given a successful login to the web service, is there a way to navigate to the account page without having to enter credentials at the login screen?

Thanks,

Jeff Penrod

How would I go about forcing a screen pop on a user's SF.com session?  For example, a caller dials into a telephony platform which asks for an account number.  Then the telephony platform utilzes a web service to identify whether or not the caller is an active lead.  Once confirmed and the call is delivered to an agent (using both SF.com and the telephony system), how can the user's SF.com session be directed to display the corresponding caller record?
