It used to be extension number and voicemail pin.
Now it's supposed to not even ask for it, so I'm unsure. You can try the ext and pin, but I wouldn't hold my breath on it.
After you reset and upgraded, the phone still found the old RPS entry.Okay, so I've deleted the phone from the extension, factory reset the phone, upgraded the firmware. Now when I try add the phone back to the extension and restart the phone I'm being prompted on the display for a username and password.
After you reset and upgraded, the phone still found the old RPS entry.
So when you added the phone the 2nd time the credentials it learned earlier and invalidated.
At this point simply factory reset once more, and the phone will pull the latest RPS entry from the servers instead of trying with the old one.
