Bear with me, I'm new to networking and general VOIP platform.
I have a 2811 router, running IOS 12.4(15)T1 (adventerprisek9-mz). I'm trying to get CME 4.1 configured. I'm trying to load the telphony_services webpage so I can configure CME. Unfortunately, all I get after logging in is gray background with "View window" in the left-hand corner of the screen.
I need some assistance with relevant reading materials or troubleshooting.
