Do you think this is because Thomas enabled CAC and I did not? I can make calls between my wireless 7925G and my wired 7940G on both Gold/Platinum but the phone will not even come online if its silver/bronze. I am also only using 802.11a 5Ghz. Not sure if that makes any sense. But honestly thats the only thing I've done on my controller..its all default otherwise.
