Personally, I would rather have less access to that kind of information so that 
you have less responsibility to collect it… I seem to recall the data retention 
legislation being very clear that if you don’t have access to information, you 
aren’t required to collect it. I think this is more about making the 
Apple-using customers happier because the services “just work”, regardless of 
how locked in or privacy-encroaching it may be.

Also… TR-069 is plain text, so couldn’t you sniff the packets to get the 
config? You may have to factory reset the ISP-provided router to force it to do 
a full refresh, but that and packet captures is something I’m sure many of us 
would do regularly.

Difference is on NBN your landline is converted to a VoIP line and provided by 
the ISP. Said ISP won't divulge the SIP configuration so if you want to use it 
you're locked in to using their provided router. A router which dials home for 
config and happily feeds back all the leases it gives out to client devices 
back to the ISPs controller.

I understand networks perfectly well. The difference here is that the router is 
not usually preconfigured, rather it pulls its config down using TR-069. Not 
usually a problem if you don't mind plaintext configuration being sent. The 
issue however is that the ISP in question refuses to divulge the SIP 
configuration, so it simply isn't possible to get away from using their poorly 
configured and insecure router unless you're prepared to do without the line 
you're paying for, or fiddle with the router until you can force its heavily 
gimped down firmware to divulge things it isn't supposed to divulge. You can't 
even turn off the service to prevent it reporting back.

On that topic... What is everyone's thoughts on the prospect of ISPs recording

given what DHCP leases and the like? Seems a bit invasive to me given none that

this information...

This is no different on the NBN than it is for anyone who has, over the last 
however many years ADSL and HFC cable services have been offered, connected 
their internal network to an ISP-supplied ADSL/HFC router which provides DHCP 
services.

If you understand networks enough to recognise the risks, chances are you're 
not relying on your ISP to hand out your DHCP leases.  If you don't understand, 
you don't know what you don't know, and are in the same situation you've always 
been on.
