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).

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.

The JS-200 runs a very old ( 1.4 ) version of Asterisk

I have set up more than 30 nodes using the HP thin clients, many using the available cheap T5720 units. Install the latest AstLinux in the flash, and follow the advice for a PSTN provider. I prefer voip.ms here in the US, and they also will deliver via IAX, which I prefer as SIP has so many hacking attempts I just don't want to deal with it.
AstLinux in our private peer to peer network, along with many also having a PSTN connection, is easy to set up, easy to support remotely, and with a flash based system very reliable.
also Astlinux has a built in facility for an in place upgrade. It also doesn't have the PITA configuration of a PIAF. Standard Asterisk conf files are used
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.

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.

And you would lose the Italian equivalent of 911. In the US, everybody

it is kind of a 'non-issue' :)

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

2) Ditch the 'room warmer' and find something really small and cheap to

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

3) For the IP phones, check out ebay.com. Last year, I picked up 3 Polycom

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.

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.

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:
