I am trying to automate login to a phone at a desk when a user logs into the workstation. I can find what phone it is, but I don't know where to send the user information to log in.

Is there a web service I can call? Is there somewhere I need to send an HTTP post to? If so (in either case), what directory would it be located in on the phone server?

Thanks,
Trevor

there are alreayd several application developed for this function. try google and enter cisco single sign on, this should point you to the right direction. i came across a product called ALM a couple of months ago, look for this using google.
