Hi guys,

We currently have 2 dwellings on the same property, all sharing one standard phone line. I'd like to move to VOIP, and am looking at running the 3CX PBX software. What I would like is to have all the analogue phones in each of the houses to be one extension on the PBX, so 1 extension per house. I've been looking at various VOIP gateways as a means of connecting the exisitng analogue phones to the 3CX system but am unsure what device I need. They all seem to be talking about incoming PSTN lines, not connecting existing analogue phones to the network.

Does anyone have any advice as to what hardware I should be using? Would the Lynksys PAP2T device as seen here http://www.kiwilink.co.nz/voip-hardware-setup.php be suitable for what I'm trying to achieve?

Any help would be greatly appreciated. Thanks in advance.

The PAP2T will work fine but is now an end of line adapter and has been replaced by the SPA2102 which is a far superior product. The most significant downside of the PAP2T is that it doesn't support T.38 for fax and can also only use G.729 on a single line, you can't do G.729 on both ports simultaneously.

How do you plan on connecting 3CX to the PSTN? Will you be using SIP trunks or an FXO adapter of some sort to connect to an existing POTS line?

There is also no need to buy the hardware from Kiwilink - there are plenty of places who sell ATA's.

Hi Sbiddle, thanks for your reply.

I'm hoping to do away with our POTS line, and just sign up with a VOIP provider using our broadband connection. Would the SPA3102 allow me to set up each of its RJ-11 ports to be exposed as seperate VOIP extensions for 3CX?

Cheers.

Yes. Both ports can be individually registed as individual extensions.

Before you go down the 3CX track is there any reason why you have chosen this software? What VoIP provider do you plan on using?

Excellent thanks. Mainly chose 3CX as its Windows based and I already have a Windows machine running that could be used. I'm guessing you'd recommend Trixbox? What features / advantages would it have over 3CX? Haven't decided on a provider yet, was looking at VFX, I take it they are who you would recommend?

First off there is no official support for 3CX from WorldxChange - you would have to contact them first to see what the current status is with support and the ability to connect a 3CX system to VFX.

There are pros and cons with every PBX solution out there, it's really just a matter of matching your requirements with the features that each offers. There is no single best solution.

You you actually need PBX functionality? You can make things more simple by just having a couple of separate VoIP lines.

Understand

There are also alternatives to the above.
- you can transfer calls between VFX lines, its a standard feature
- you would have a different number for the second house - so possibly an advantage
- you can transfer out of voicemail to the other line

So really comes down to the end result of what you want to achieve.

If you do decide on WorldxChange, I am one of their Dealers, so can help you with a few ideas and get you setup.

3CX works fine and is certified on our DVX platform, be sure to ask for an Asterisk account when signing up. You can simply use the username/password to the applicable settings in 3CX.

+1 You don't need PBX, just ATA with two FXS

$180 Dynalink RTA1046VW has two FXS (for two analog telephones) So you may take two accounts (lines) from one SIP provider. In additional, it has a PSTN FXO port (for traditional land line) and a wireless access point. I did try calling from one FXS to another FXS (from one phone to another) through Voxalot. Worked fine. Supports call transfer, conferencing..though could be registered with only one SIP provider at the same time. if you need to have more than one SIP provider you may use again Voxalot (www.voxalot.com)

I use 2talk and they have a feature for extensions where you can transfer calls between the different numbers on your 2talk account.
If you have a number on there for both houses then you could transfer calls between these 2 numbers by assigning them an internal extension.
May save you the overhead of putting in a full pbx.

Have you looked at the Grandstream ATA devices? These interface into SIP and also have the RJ11 for failover or for direct POTS line access.

I got myself a Linksys SPA2102 and have tried it connected directly to 2talk which works well, and I'm also playing around with connecting it to a local box running 3CX which works really well also. Just a case of playing with the setup and weighing up the pros and cons of running a local pbx. Pretty impressed with how easy 3CX was to setup and administer. Its all good fun, learning lots

Will give the linux / asterisk solutions a go too, got no shortage of old computers lying around to play with. Thanks to everyone for their help.

Just be aware that Grandstream has a history of making poor quality products. The performance of their ATA's is only average at best and I wouldn't touch one. There are plenty of other devices like the SPA3102's that offer POTS failover that are of far better quality.
