Hi,
I'm finalising the wiring for a new house build, the wiring is exclusively CAT6.
Internet connection is via TCL cable, (as far as I know there is no Chorus cable in the street at all).

I'm trying to decide which equipment to select for providing VoIP phones (Naked broadband plan).

I want a single local phone # to be able to ring multiple VoIP phone outlets in house (similar to conventional phone).
- Can this be done by just programming same configuration into both ports on SPA112/SPA122? or does it need to be setup with the VoIP provider. (2Talk or WorldXChange)

Option 1.
TCL Cable Modem -> SPA122 -> 2 x Analog phones
                                          -> Network switch/router/hub -> PC's + Media Server + TV
This should provide good call quality as the SPA122 handles all QoS priority management. No need for QoS setup on
internal network hub.
Issues.
Need to identify phone/data outlets on wall faceplates so as to prevent connecting ethernet equipment to phone outlets.
SPA122 - Can this have same number for both ports? (so both phones ring together?)
           - or need to make a special multi-drop patch cable to connect multiple circuits to same port

Option 2.
TCL Cable Modem -> Router -> SPA112 -> 2 x Analog phones
                                         -> TV, Media Server
                                         -> Network switch(Gigabit) -> Computers
Similar to Option 1 but cheaper (SPA112 cheaper than SPA122) already have router.
Setup slightly more complex as need correct QoS configuration on router.
Issues.
Need to identify phone/data outlets on wall faceplates so as to prevent connecting ethernet equipment to phone outlets.
SPA112 - Can this have same number for both ports? (so both phones ring together?)
           - or need to make a special multi-drop patch cable to connect multiple circuits to same port

Option 3.
TCL Cable Modem -> Router -> VoIP handsets (Seimens Gigaset and/or Cisco SPA301)
                                         -> TV, Media Server
                                         -> Network switch(Gigabit) -> Computers
Simplest from the wiring perspective - all circuits the same.
Most expensive VoIP more expensive than ATA
Same question about sharing incomming calls across multiple handsets.

All comments / suggestions welcome
Thanks
Colin

You can plug multiple analogue phones in to an ATA - up to about 5 seems to be OK, but will depend on the ATA and the phones used. It will work like an existing POTS landline.

All the various RJ45 outlets around the house should come back to a central patch panel. From there, you can patch each one to be either a phone or ethernet outlet as required.

Had you considered a router with ATA built in? That would then handle all the QoS requirements easily, and give you a couple of analogue phone lines. Something like a Cisco SRP521 would do the trick, and if you decided to go for WxC VFX (Xnet) for phones, then they can auto provision it for you.

I'd still say that wiring for POTS from a central ATA is your easiest and most cost-effective bet. Or just put in a DECT Cordless system next to your ATA, and put chargers around the place with handsets.

Yea just run the ports backt o your patch panel. Then on your patch panel, on the back run some cables between pins 4 for say 5 spare ports and pins 5 on the same ports. You can then patch one of those ports into your ATA and the others into the numbers ports which go out to the rooms.

Get yourself some siemens gear =) The base unit is completely separate from the charging cradle for the DECT phones. The base will take the registration from your provider and then you can select what phones incoming calls should ring and then make calls out like any normal phone. Probably not as cheap as using an ATA and analogue phones but why waste wall outlets when you don't need to. One base can have up to six handsets on it.

Not sure I see any real issues just use an ATA as the house will be wired anyway pretty easy to number a socket. Just have a central place where all the network gear and modem will be with the terminating sockets that correspond to the sockets throughout the house. I personally would design it so all of that is in some sort of cupboard.

Yes basically your "option 1" but the ATA has different phone numbers for each outlet so if you don't want to join the blue pairs on your patch panel ports then use a 3-way RJ11 joiner to get analogue phones onto same number. Definitely worth keeping the whole setup hidden away in a cupboard or wall cabinet.

Time to find a new industry!

Wire the House for data only, then get an Atcom IP01 PBX or something similar then use either an IP phone or
ATA and analog phone for each extension, that way you can use 1 Phone number for the whole house while still being able to do multiple simultaneous calls in and out and if go with 2talk as your provider you can use IAX2 so no issues with nats or firewalls.
Of course you can do all that with 2talks cloud system anyway utilizing the free 028 numbers with out a IP PBX which might be easier.

This isn't super relevent, but make sure you make provision to change from TC to the national optical fibre network thingy that's starting to be rolled out without having to drill holes or pull walls off to get at stuff.

I forget the name, it's too early in the morning.

You can acheive that with the gigaset gear. Which is IMO the best option. POTS is out. IP is in. Why bother converting IP back to POTS?!

I agree, just that Pots and ATA are still much cheaper than the Gigaset gear but if money is not an issue....

It isn't that much more though really. It is a drop in the hay compared to the house build so why skmip on something that is important. An a510ip base station with handset is just over 200 dollars and then the handsets are less than 100 each. What is being spent on the home theatre system? So again, why skimp out on comms?
