I am trying to provision a Linksys PAP2T that I bought off of ebay. I entered the url as the provisioning rule in the router advanced admin settings. It didn't seem to be working, so I double checked I entered the MAC address correctly and in doing so I noticed the MAC address shown on the sticker on the bottom of the device is different than the MAC address shown in the linksys admin control panel. Is this normal? Which one should I give to voipo?
