Anyone know why some consumer routers need port forwarding declared for VoIP ATAs and others don't?
I can reverse the question ... I've had several VoIP providers and have never had to use port forwarding with my ancient router. Recently, I've started having a variety of issues and have started experimenting with port forwarding. So I guess, my question would be why my router works perfectly well with other providers but appears to have an issue with VOIPo.
