Hi everyone

I don't know for sure this is the right place - but thought I'd start here and see where a discussion might go. I'm NOT a very sophisticated Telecom user - and since a stroke four years ago I've even got doubts about my PC knowledge. I've even resorted to using Windows because support for my long time OS is limited.

So I'm looking to set up an office at home. I will keep the home line separate - not least for access in a power cut. But I'll have our old numbers transferred to VOIP and upgrade our existing Xnet connection so it's not limited in upload speed. That much I just about view as simple.

But today I went to take a laptop back to our supplier, who happens to be the recommended firm down in the capital for Xnet VOIP equipment. We were given two part numbers - both by Linksys. One's a PAP2T and one's a SPA2102. Now after talking to the staff and checking the internet, I'm still in a dense cloud of confusion.

We have a phone / ISDN connection coming into our dining room. That will be where my wife plugs her computer in. I will have my office down the hall in what used to be my daughter's room. We used to have a cable down to there for a computer - need to check it's still working but if not we'll replace it.

Now we will have two phones connected to the VOIP lines. It would be idea if one could be based in the bedroom / office - there's some talk that we could use a dual handset for that with one near the ISDN set coupled with one in the bedroom / office.

So we're trying to get this clear - what exactly do we require and what might be useful?

Thanks for any help.

The spa2102 is the one I will recommend , it's newer hardware and generally a old round better device.

If you have a ADSL router which I will asume you have , you can have the 2102 sitting behind that which will just run your office phones, as you have suggested a DECT phone with a second handset would be fine for the second room so you could have one in your your office and the other main unit plugged into the 2102.

Your internet connection for your office can come directly off your router where ever you have that set up, you mention you may have this cable already installed , if not it will need to be cat 5 cable, you could use wireless but really depending on your router and it wireless capablites B / G/ or N unless it's N wireless lacks the connection speeds you get with a wired connection.

Thanks - still don't understand all the ins and outs the guy in the shop tried to explain - but at least that reply is simple enough for me.

You have an ISDN line going into your house? Are you sure?

Oh dear. My excuse for this is my woeful short term memory resulting from a stroke four years ago. Funny thing is I had actually said ISDN elsewhere and picked it up. Didn't know I'd said it more than once. ISDN (for me anyway) goes back a long way - and it's fairly typical that older stuff stays in my brain more easily than newer stuff. Sorry about the confusion I caused. Have to get my wife to check more of my messages - she normally acts as a memory check to make up for my faulty memory.

Hi

The Voip industry tends to supply specialist devices to connect an analogue phone (like the PAP-2T) connecting to your existing Broadband router, or Integrated device (like the SPA2102) which does double-time as both a Internet router and Connection point for your telephones.

How you actually INTEGRATE the telephone wiring and location of devices in your home is NOT covered by these devices.... that's left up to the individual customer and is unique to your own situation. 

A scenario includes, for example:
A power socket and Telephone connection near your computer. You plug your IAD into the telephone socket for DSL, your computer into the switch ports, and a telephone into the back of the IAD. Nice, neat and all in one location.

If you have telephones distributed around the house in serial fashion (ie, 2-4 phones connected to one 'telephone line', so all ring when a call comes in), then you need to 'reticulate' the voice connection, and this is where things become a little more involved.

Your connection today is from the outside (Telecom, TelstraClear) into the house. The VOIP model tends to be Inside the house fed back into the wiring.

The industry is working on broad standards for adoption of this model, but they haven't really hit the bigtime yet, as the industry is still in it's infancy.

A good electrician should be able to wire up what you could want; Chorus have some good products for premises wiring, but these need to come from your service provider as they are not direct to end user; or just use loads of dect phones around the place!

Thanks for that info. I was going to just use the existing phones from the office - but now it looks like I'll buy a DECT phone for the far office / main phone number.

It is also useful to buy a cheap UPS. Can be found for around $100 to $150. If power goes off it is useful to keep powering your modem/router/VoIP/DECT.

That's a good thought - we used to have an old UPS - hadn't thought about it for this.

A cheap UPS will run a normal PC with monitor for about 15 to 20 minutes. You can expect a lot longer for only a modem/router/phone. Should be a few hours to maybe half a day. In ~5 years I've never checked but did have a few power outages lasting a couple of hours.

Keep in mind the batteries (usually 2x 12V 7Ah "gel cells" lead acid alarm batteries) should be replaced every 2 to 3 years. They do not last for ever. It is about $40 to $60 per battery from the usual places, I get them for $20 each because our company buy lots in bulk (for electric fencing). Very easy DIY job, just a few screws and quick connect terminals.

If you are technically minded it would be more efficient to skip the UPS and just have a 12V battery driving the gear (which is all 12V rated) and hook up a small trickle charger. I'm an electronic engineer, yet can't be bothered doing all that. Also my UPS is driving my PC as well with clean filtered AC power which makes the PC power supply last longer.

There's one difference between us - I'm not at all technically minded. But I will check into UPS gear for the phone etc - our computers should be OK as they're laptops so have their own batteries.

Thanks
