    I am trying to make a setup as follows:

    using (free) 3CX Phone system, I have set up 3 internal extensions (100 - 102).
    I have one external VOIP line, it is a Gizmo Project (SIP) account ("dinjafr_be") Currently I only allow outgoing calls.
    I have one outbound rule that says: all outgoing calls use the Gizmo VOIP provider.

    on a 2nd machine I have Gizmo Client running (logged in as "johandm_be") and on a 3rd machine I have 3CX softphone running. It is connected to the 3CX phone system, it is extension 101

    if I try to call my gizmo ("johandm_be" or the actual number number, the result is the same) from 3CX softphone on ext 101, then Gizmo client rings (OK!!), but if I pick up there is no sound (in either direction).
    The connection gets dropped several seconds later, and on the 3CX phone I see : "protocol error, layer 2".

    I verified that I opened ports 9000-9003 on my firewalls (since I did not know what protocol, I did it for all of UDP, TCP and ICMP)

    I've pasted my log from the server below. Any advise would be welcome.
