i maybe a victim of being in korea but... my voip just stopped working one day (i'm using a linsys wrtp54g) and was told to put another router in front of the voip router to get it to work. it did for a day and now after factory defaults it still is not working. i think i either messed up something or the local isp is blocking my service. got any helping advice? i know a little about info tech but not enuff to fix this!
