Hello everyone. I have 3 GXP2160 phones on my system and I have been able to upgrade 2 of the 3 to 220.127.116.11 firmware. One phone however isn’t upgrading. It is on 18.104.22.168. This version does not have the ability to upload a file through the web GUI like the later versions. I have rebooted the phone, changed how often it looks for new firmware, factory reset the phone, and even tried running HFS and pointing the phone to this local server to get the file (which I see it will do) but it fails to update.
Any ideas of what I can try next?
