Good morning, do not have your name but thanks !
There is now more to it. Last night I decided to connect the phone directly to the Internet as to get a public IP with no NAT.
I was able to call someone and have perfectly well two way audio BUT the person when trying to call me said :" I get a ring tone once and then defaults to busy tone". I never get the ring, in summary I cannot rreceive calls and now there is no NAT whatsoever........................ I am really puzzled.
I may need to get the Admin guide. The box came with a CD ROM and some papers but there is no (at least I cannot find it) a technical manual with every setting and what it means.
Thanks again !
