    We checked our Firewall and from that perspective everything is ok.

    Could you please give us advice how to solve this problem.


    Thanks.

    OBP= Outbound Proxy

    Are you missing something in your trunk settings?

    Hi,

    the outbound proxy should be set to nat.voiptalk.org

    if you continue to get issues, you can leave this out and it should register ok.

    the outbound proxy is not always required to get 3CX working with VoIPTalk.
