John;
I have a 4150 (ext 105)on my desk, and version 4.0.4.9 on my icp controller. The icp controller is providimg dhcp for all of the devices in our office.
I have the 3.0.8 version on ya lite. When it loads, I'm entering the IP address of my controller, my ext number, and the display says the ext is not available.
