Hello all,
I'm new here and I'm interested in building a small PBX with asterisk at
home. I have one single PSTN line and ethernet cabling in place. I
already have fairly decent PC that I can use (AMD FX 8350 16GB of RAM
and RAID 10 SATA disks). I make and receive 10 calls a day on average. I
want 4 IP phones connected to the ethernet network. When there is a
incoming call, all phones must ring and the first that takes the call
makes the others stop ringing, but lets them available for internal
calls.
Given the requirements above, what's a cheap but working PCIe card / USB
adapter I could buy for this kind of PBX? Do I need things like echo
cancellation? Do I need FXS ports?
Thanks in advance,
Lucio.

Hey Lucio,
You will need a FXS port. I would recommend setting up something like Cisco SPA3102.
The SPA3102 can be found cheap on Ebay, and will be easy to setup in Asterisk.
http://www.infoworld.com/article/2633694/data-modeling/your-pstn-and-you--linksys-spa-3102-and-asterisk.html
Once the FXS is set up, it's just a matter of adding a ring group/pickup group:

You could have used a system that is a bit less powerful. But anyway, I
guess that those are not that expensive nowadays. For that kind of load,
even a much smaller server would do.

This is a slight confusion. The SPA3102 has both an FXS and an FXO port.
What you need is an FXO port - a port to connect to the PSTN as a phone.
An FXS port allows you to connect an analog phone. It is something you
could have used for local extensions. But you already have IP pohnes.
Again, I guess you meant the FXO port of the device.

Yes, I did.
My bad, always get the two confused. *sigh*.

You need an FXO port for each exchange line, and an FXS port for each analogue
telephone you want to connect to the PABX. (If you want to use proper
hardware SIP phones, then you don't need FXS ports.)
You can get inexpensive PCI / PCIe cards which accept up to 4 modules, either
FXO or FXS, from the usual place online. They are drop-in compatible with
Digium cards. I would never use one of those in a mission-critical,
production environment, but they are fine just for experimenting with.

I don't know this 'translates' to Italy, but this is what I would advise
somebody in the US to consider, assuming you have a reliable Internet
connection.
0) I hope you mean you want to run Asterisk at home instead of 'Asterisk
at Home.' A@H was an ancient distribution from around 2005.
1) Rent a DID (a 'PSTN number') from a reputable SIP provider. This
eliminates the need for a PCI/USB interface and you won't disrupt your
'business' while you figure out how to configure and test your Asterisk
server.
In the US, you can rent a DID for about $1.50 per month and about a $0.01
per minute of 'talk time.' For 10 calls per day, this should beat the hell
out of a 'landline' monthly standing fee.
In the US, it costs less than $20.00 to 'port' your existing number if you
are really in love with it.
2) Ditch the 'room warmer' and find something really small and cheap to
run. I live in San Diego and we pay $0.32 per kWh. I'd guess running your
rig would cost me $50.00 to $100.00 per month just in electricity -- and
probably that much again in the summer for additional Air Conditioning.
Take a look at Soekris net4801. It's pretty old (but very reliable) and
it's CPU will limit you on what OS you can run, but it will give you an
idea of how small (and cheap to power) an 'Asterisk server' capable of
handling a couple of simultaneous calls can be.
For a more modern server, look for something small and cheap based on
something like an Atom processor. Maybe a used laptop. If the battery is
still good, you've solved your UPS problem as well. Although, if you lose
power, you've probably lost your Internet connection as well so you could
only make calls between extensions.
3) For the IP phones, check out ebay.com. Last year, I picked up 3 Polycom
SP 501's for $20.00 each. A little dated, but a great phone.

And you would lose the Italian equivalent of 911. In the US, everybody
over the age of 6 has a cell phone stapled to the side of their head, so
it is kind of a 'non-issue'

I gotta agree with most all of this. Asterisk has been shown to run on a Raspberry Pi and the Raspberry Pi 2 and will handle a few simultaneous calls. Another resource is http://www.plugpbx.org/
For home use, I would think either would be a good low power way to run Asterisk. Unless you just really need the land line, ditch the analog line and go voip from start to finish. |

I picked up a cheap JS200-FX on ebay: http://x100p.com/products/js200fx.php for $30, and it works great for a home install. Very low power draw as well.

The HP 5720's also have a 120-240 volt power supply, so it should work almost worldwide
Somewhat larger than a Pi, but in a decent case that could easily be mounted on a wall somewhere and connected to the LAN
Other newer units with multiple NIC ports and AstLinux can also be your router /firewall
Unless one is running a 100 seat call center, no need for one of those huge juice hogs anymore.

Good day,
i am using a raspberry pi 2, where i am running asterisk 1.8. it runs really well.
to interface the 2 PSTN lines i am using 2x linksys spa3102
costs:
-raspberry with case and power supply 50€
-spa 3102 25€ each.
total=100€
also i do have a couple of sip trunks with betamax.
the PBX serves 10 users, i have seen 7 concurrent calls, at g711a.
it is really cool machine.

I would get hold of some lower-power hardware, that system seems hugely
over-specified for what you want to do.
A raspberry pi & a Cisco SPA-3102 would be a good solution. Cisco don't
make the 3102 any more but there are still plenty of them around. I
believe Grandstream still make ATAs as well but I've never thought very
highly of them. As others have said, it's an FXO port you need.
You want to avoid transcoding on low power hardware such as a raspberry
pi so set everything for a codec such as g711a or g711u (Asterisk, the
IP phones you use and the SPA3102).
