coffeebaron: You can rewire the phone output from the VoIP box into the internal wiring (if you know what you are doing). I do this for many of my VoIP / Naked broadband installs.

Yep, exactly what I did at home with naked DSL - disconnected the internal wiring from the POTS line and rewired it to a Linksys ATA. Works like a charm although obviously you are limited by the number of extensions your ATA can power.

And how many extensions would you expect your ATA to power? or is it a trial and error thing? for example, could it power two traditional corded phones and a cordless powered phone?

You will need to calculate this yourself because it depends entirely on the ATA and the phones. As part of the Telepermit spec every device has to show it's REN which is also available if you look up the Telepermit on the Telepermit website. An ATA is typically around 3, and most modern phones are now well under 1. The sum of all phones can't exceed the REN of the ATA.

And to add to Steve's comment the REN of a NEAX (Telecom Exchange) is 5.

I go by the theory that an ATA or router with a voip to analog converter in it such as the genius or a typical voip ATA will run 3 telephones wired on the analog port

And a telecom Pots standard landline will support up to 5 - though it may affect your DSL if there are more than 4.

Im thinking about going with Fusion at our holiday house and connecting the internal POTS loop to the VoIP router. Would you care to elaborate on how this is done? I have installed CAT5/6 before and am familiar with patches and punchdowns but have limited experience with POTS.

What I did was remove the POTS loop from the incoming line at the ETP.

I had earlier run a CAT5 from the ETP to my ADSL router. I used 2 pairs in this for line 1 & 2, the third pair I terminated to the POTS loop in the ETP with Scotchlocks. I terminated the other end of this pair to the patch panel where my ATA was mounted (next to my ADSL router). RJ45-RJ11 cable to the ATA

Pair 1: ADSL--Patch Panel --ETP--Line 1
Pair 2: Patch Panel--ETP--Line 2
Pair 3: Switch--ATA --Patch Panel-- ETP --Internal POTS

Works like a charm and is easy to work on if need be.

Several ways to do it; but basically as above, cut the POTs loop at etp. Run a feed for DSL on the "live" feed (from where you cut). Run a feed back to the "dead" feed (from where you cut) to re inject the VoIP into the POTs loop.

REN refers to the amount of ring current (ie only the current drawn during ringing) that the line port can supply, and yes 3 is a good number for an ATA. There is an assumption that only one or two devices will actually be across the line during the call, but all devices will pull ring current.

The max number of DSL micro filters that should be put in parallel before they start to impact on DSL performance is typically 4-5, but if you use a master filter it can be greater as only one filter is seen to be across the line in the DSL band.

Something like a Siemens Gigaset IP phone and extra handsets would be ideal for your neightbours scenario. Each phone can work with multiple different numbers, you just need to have the VoIP accounts as others have described - 2talk, vFX, or a UK/US one aswell if you do lots of overseas calling
