Couple of questions about Openreach ONTs

Hi Everyone

I am asking these questions on behalf of someone who is considering getting FTTP.

As some of you know, Openreach ONTs have a phone port on them. I think that if the master socket is connected to it, it enables analogue phones around the house to work. Am I correct?

Does anyone here know if it is possible to log on to an Openreach ONT (via a web browser interface) and configure the SIP credentials for a third-party VOIP provider such as Yay.com?

Thank you very much.
 
I've never heard of these ports being used by Openreach or most other UK fibre networks for that matter. With digital voice it would almost always be the telephone port on the back of the router or an ATA Device that would offer the telephone service. Similarly, all things like authentication would be done on the router rather than ONT so I don't believe an end user would generally be able to access any ONT configuration either.

I would also be careful to not mess too much with the ONT as that's Openreach's property and trying to modify the ONT confirguration would likely be considered similar to mofifying connections behind the faceplate of a master socket - Something the consumer shouldn't really be doing.

Thank you, Koda and NinjaAverage very much for your replies.

Does anyone know how to connect an ATA to the master socket so that all of the analogue phones in the house can be connected to the ATA?

Thank you very much.
 
As said, those ports are long gone, but they can't be used even on ONTs that have them. They were used for an Openreach service called Fibre Voice Access which was an earlier attempt to replace copper phone lines, but the ISPs decided to take that in house as a feature within their routers.

This can be so variable.
I've had it work in two houses. And not work in many more than that.

The usual problem appears to be interference picked up by the phone wiring which somehow gets "absorbed"? by the BT network and isn't a problem but becomes a problem when the internal home extensions are wired into an ATA/phone port on the back of a router.

I strongly recommend buying a native VoIP phone or plugging a single analogue phone or base station into the ATA port only.
 
Hi Everyone

Thank you very much for all of your replies.

I have started a new thread in order to ask this question in a clearer way. Here is a link to the new thread:
