I had been having issues with making "url idle" changes to my configuration, resetting phones, and them not obtaining this configuration. I must have made the config change a couple dozen times. At some point, they 3 phones I have in my lab received the config change but when I removed it from my Unity installation, they KEPT loading the "url idle" long after it was no longer in my running or start-up configuration.
I rebooted the CME router. While the router was down I physically powered cycled the phones. Once everything was back up, the phones STILL had the "url idle" values configured! While in the SETTINGS of a particular phone, I typed *,*,#,*,* to unlock and choose "Erase" on the HTTP Configuration option. This removed all the entries, but now I can't get them to populate again with the fields I actually desire: Directory, Services, Authentication, etc.
I'm at a loss why my GUI and CLI changes to my "url" paramters are "sticking" on the phones, and not being downloaded to the phones upon a reset.
