Re: [SR-Users] REGISTER failure_route 401 problem

Are you sure you have set t_on_failure() for the respective transaction?

Cheers, Daniel

So I've found out that NAT has nothing to do with it. The bit about things working when the NAT device is removed was wrong.

So my question becomes: Why would Kamailio ignore a 401 rather sending it to a failure route?

Thanks in advance, Marc

I forget to mention, the nat device is in front of the Kamailio
servers, not the endpoints.

    I have a Kamailio server setup which is registers to a back

    to Kamailio but Kamailio is failing to register to the server
    when I put a NAT device in front of it.  Without the NAT
    device it works fine.

    The problem is the 401 that comes back seems to be ignored by
    Kamailio.  I have a failure route setup to auth, but it is
    never hit.  I see the 401 in onrely_route, but not the
    failure_route.  I'm assuming it's a NAT issue because removing
    the device fixes the issue.

    Anyone have any ideas?

    The 401 being ignored:
