Another way to do this is create a user in call manager that you know the password for, then associate the remote phone(s) as controlled devices to that user you created. From the Device > Phone page you can get the IP address of the remote phone, if it's a newer phone (7941/61/70 or newer) you can access http:///CGI/Screenshot.

If you want to check on an older phone 7940/60 let me know and I'll post that procedure since the image file will be in hex and will need to be converted.
