I'm having the same issue. Occasionally, when we make calls out of the house, the person we call can hear us, but we can't hear them. If we try a couple of times, it connects properly. Unfortunately, I am not as tech-savvy as a lot of VOIP users, so I'm not getting what a lot of you are talking about in this thread. For example, I don't know what "port forwarding" is.

Can you help a newb out? How do I fix this?

Thanks.
