Programmed up a SPA2102, plugged it in at a friends place (just with power) and it promptly reset (or at least it's dropped its config between when I unplugged it at my place and pluged power in at his).

Anyone seen this happen before?

I used my tftp server and dhcp option 66 to drop a config on it,  Is there something I need to change when I take it away from the home network?
