    Hi Nikos,

    server is ims.otenet.gr on 5060 and outbound proxy the same,
    you have to enable 3way authentication. Authentication ID is your username +302xxxxxxxxx , Authentication password is the password they sent you and is second Authentication password field you put +302xxxxxxxxx@ims.otenet.gr

    You have to disable sip trunk from router and refresh registration on 3cx.

    Try in outbound parameters "from: user part" with variable "leave default value"
    Disable and enable again registration after that and wait 30 seconds

    By the time it now shows as "Registered", I think this may be point where you should give OTE a call to ask them what they see wrong. If you post here whet they tell you, we can say what change to the In/Out parameters need to be made...

    Do you have the Authentication in the trunk set as "Do not require - IP based" or "Register/ Account based" ? It should be set to "Register/ Account based"
