When I do a Skype-to-Skype call from the US to Israel, within about 3 minutes my entire Internet connection drops. (i.e. the call disconnects and I lose Internet service). It's happened about 10 times in a row, both when I was talking with 1 person in Israel and conference call with 2 people.

To get my Internet connection back, I have to reboot my cable modem and router.

SkypeOut to Israel works perfect without any problems. And I never experience this problem when doing other Skype-to-Skype calls within the US, or SkypeOut calls.

Any advice?
