I suspect the OP originally had ADSL or FTTC and at some point upgraded to FTTP before DV existed, so either opted to keep their voice service on the original copper, or had to as FVA was not available. BT are now migrating their customers to DV.

Unless this voice service is used for outgoing calls there doesn't seem much point make major changes given that the BT FTTP only prices are pretty much the same as FTTP+DV, and in some cases with special offers FTTP+DV is cheaper, so as the OP originally asked plugging the N300 analog connection into the BT socket on the Superhub 2 is the most straightforward migration.

Also, ISPs still use the PSTN DN as a service identifier porting out the number would likely cease the FTTP service too. Given the combination of migration routes which may be required ISPs seem to have given little thought to the processes required, or maybe they just want to keep the customers voice service to make more money with their excessive call rates or optional call packages.

You and MHC seem to be missing what the OP stated at the beginning!

I have BT FTTP (Smarthub 2) and a copper landline that is being moved to Digital Voice
...
As it is a PSTN port ....

They have FTTP and are moving to Digital Voice. Simples. Therefore, no analogue (PSTN) phone service supply in the future.

Both of you are describing how to implement precisely what they have and are moving away from.

No, Describing how to connect the OPs analog input of the N300 to the Smarthub2

The phone port is an output it is NOT PSTN. It is specifically labelled "Phone Port for Digital Voice Customers Only"

There will be just a fibre coming in, no copper. The voice is then "Digital Voice" and the SmartHub converts it back to analog and presents it on the port which is what the OP is hoping

I was simply going by the "fact" stated by the OP. A PSTN socket.

Plus this from you:

In reply to a post by MHC:

However, the Analog output from the SmartHub2 mimics a PSTN/Copper connection and it should be possible to then connect that into the Gigaset N300.

That now appears to be either junk, or simply very confusing.

Are you saying the Hub is outputting an analogue phone signal, which is what the N300 currently expects, or on DV will it output a VOIP signal which the N300 presumably can also handle as it can accept three such?

The word "mimic" is one thing that threw me. Surely it is one or the other, not one pretending to be the other. Then of course, both VOIP signals are (I assume) coming down the same connection to the N300 anyway.

It would seem strange to turn a BT digital signal to an analogue one to get to the N300 then change it back to digital to get to the handset! How is the current VOIP service connected to the N300? Why should a second physical connection be required anyway?

Both will be digital coming down the same fibre from Openreach. The existing physical connection should handle both.

Edit: The "phone" socket on the Hub should be redundant. The OP's question surely doesn't arise?

Posting in the early hours has led to huge confusion. You need to reconsider in the cold light of day.

MHC's post at 22:43 states the facts.

The SmartHub 2 includes a basic ATA that does the VoIP/Digital Voice to analog conversion and presents the output on a standard BT socket. The user then plugs in a standard handset or as BT suggest a DECT base station.

It will only work with BT (and possibly Plusnet in near future) and no other VoIP provider.

So the SmartHub2 provides the BT DV VOIP to Analog conversion for FTTP and xDSL services

If you connect a VOIP phone base station to the SmartHUb the BT DV will operate on the "Fixed Line" (i..e. analog) side and if the user has another VOIP service that will function via the ethernet connection to the Lan.

The SmartHub BT socket can only provide an analog phone signal, there can be no conversion back to digital.

The N300 could of course handle both VOIP services but BT in their wisdom will not give out the VOIP registration details for their Digital Voice so it has to come from the SmartHub analog output.

As is typical from BT, an ATA inbuilt into their routers cannot be configure to use a 3rd party hosted service, only that from BT although any analogue phone can be used.

On the other hand, if you plugged a VoIP phone into a port of the router, your choice of providers is limitless.

If you have an FTTP service you get just a broadband service, a voice service is an optional extra. It might for a while still utilize the copper pair to your home.

I see it taking decades for redundant copper wires being physically removed.

Bob, think about what you mean by "VoIP signals" in your 2am post. To get an analogue telephone to work with a traditional BT jack there needs to be a digital to analogue conversion. This either happens in the exchange (traditional PSTN) or in an ATA (Analogue Telephone Adaptor). BT Retail have built an ATA into their SmartHub only for their customers, and it actually has a "BT jack" so you can directly attach your old phone handset.

DECT systems can of course attach their base station to this jack. Some more advanced DECT systems also incorporate VoIP ATA technology to use with the likes of SIPgate or A&A.

In this case, the OP will just plug their DECT system into the BT jack on the back of the SmartHub, and in theory the old copper line to their home will be inactivated.

I am however confused as to what the OP has purchased and from whom and what is active on which ports.

I currently pay BT £5.22 pm for 500 free minutes to any UK landline or mobile number and charges from my VOIP provider are much higher than that.

If I can connect the N300P PSTN port to the Digital Voice port of the Smarthub 2 then that would appear to be the ideal solution for me.

Why haven't you done so already?

Yes, once BT migrate your voice service from the original copper phone line to DV it is just a case of unplugging the N300 connection from the existing master socket and plug it (the N300) into the Digital Voice socket on the Smarthub 2 instead.
