Maybe that's my issue also. I was given the Linksys and I'm having the exact problem again this month. They fix it on their end. But the next month the problem returns. This month I just got so fed up with it I have ask for my account to be canceled. There are other VOIP providers out there that actually work as advertised. The worst part of the whole thing is having to convince tech support every month that the problem is on their end. Once I finally get someone to listen to me they make an adjustment and things work again. But I refuse to go the finger pointing route again this month. Good luck.
