    This is probably your problem.

    You don't need to forward ports with asterisk. Just sent nat=yes on the
    extension.

    It depends where everything is.

    If the asterisk box is behind a NAT firewall (which this one is), then a
    remote phone will be unable to register to the asterisk box unless there
    is some sort of port-forwarding going on in the router.

    And if you are an asterisk box inside a NAT router, trying to talk to
    SIP devices outside the NAT router, then you need to tell asterisk the
    external IP address it's using to send data out on, on the other side
    of the NAT router, and the local LAN IP address range, so it knows what
    to put in the outgoing SIP headers. (else it'll send SIP packets out
    with it's NATted IP address inside them, which will be passed to the RTP
    stream and you'll get the 'classic' one-way audio problem )-:
