I am on the genius unlimited plan and am generally very happy with it.

Since yesterday all incoming phone calls go straight to the answer phone, it doesn't ring at all at home. Making out going calls works fine.
This is (I think) the third time this happened since I changed to the genius modem. The previous times it was fixed by orcon quite fast.

I logged a ticket yesterday and got reply saying that if it happened again I should restart or factory reset the modem. I was also informed that my genius is on the latest firmware and that the line is testing well.

I have restarted the modem and the problem still persists. 
I saved the configuration, factory reset the modem and restored the configuration and the problem still persists. 

I wrote back to orcon last night that the problem is not resolved yet but haven't heard back yet.

Is there any advice on this? Anything else I could try to get it going again.

This problem is very annoying since one can be unaware of it for quite a while.

Thanks for any help in advance.
