This fix is to address the Host Not Found Error when attempting to use the Corporate Directory on phones after our Domain migration. On the Desk Phone:
- Press the Settings Button
- Scroll down to Security Configuration and select
- Scroll down to Trust List and Select
- Scroll down to ITL File and Select
- Press **# Keys and press Unlock soft key when available (takes about 1 to 2 seconds to appear)
- Press the More Soft Key
- Press the Erase Soft Key
The phone will erase its ITL file and Reboot. Upon reboot it will download the New Certificate from the server with the proper server name (and domain) allowing the Corporate Directory to properly connect
