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?).
