    Newbie question...

    I have setup a 3CX server and configured the firewall with all necessary static NAT mappings.
    The server is reachable as "external.mydomain.com" with default ports.
    I have tested several softphone apps (3CX, Xlite) and these work just fine.

    Now I am trying to connect a Linksys SPA942 over the Internet to an extension.
    The Linksys is behind a NAT router, but I have enabled NAT mapping features.
    The phone DOES register on the server, but when I try to dial to this extension, I get the error "401 Unauthorized":

    (PS: Another Linksys phone hooked up to the LAN of the 3CX server and registered on the same extension DOES ring.)

    Extract from the log:

    I don't understand why this works with softphones and not a hardphone... What am I missing?

    I tried in vain to get a 962 working like that in V5. I eventually set up a VPN between the two sites and got it working fine.

    Have NOT tried with 5.1, but it still works with the VPN
