Hmm, just seen one happen now.
```

What looks like happened here is that the server_id is set to 1, but the socket is not
set, so nathelper is getting the default interface from the os and sending the ping on the
wrong interface.
Here's the aor on registrar_1:
```

}
}]
},

}
```
This contact is serviced by registrar_2 and it looks like it has its socket set to its
local interface, but the server_id is still that of registrar_1 so registrar_1 is trying
to ping it.
here's the aor on registrar_2 (this one "saved" the location, why is
it's server_id still 1?).
```
