Our collectors network ( of obsolete telephone equipment ) has quite a few
users of AstLinux with both 4 port analog cards ( TDM400/410 ) as well as T1
cards and channel bank. Older HP thin clients with expansion frames that
support 1 PCI card are in use. FXS modules require 12VDC, so the units that are
powered off 12VDC ( up to T5720 ) are more suitable. The SE version of AstLinux
has to be used, as these are 32 bit.
Certainly not a "bleeding edge" application, but it works well.
As to PSTN connections, in North America, IMO the best choice is voip.ms. They
support both SIP and IAX into Asterisk/AstLinux. I have used them with IAX for
10 years, with hardly a burp on their end!
YMMV

Hello,
I'm not sure this is the place to ask this so I'd appreciate pointing me to the
right place if not.
I would like to build or buy an embedded system with fxo, fxs and ethernet
interfaces and a processor that can run astlinux.
Are you aware of such over the shelf hardware?
Thank you.
Hi Doron,
Not knowing your technical background makes it difficult to define a specific
answer, but maybe a little info.
Short answer, I'm not aware of an x86_64 box with FXO/FXS ports.
Though a plain x86_64 box should work with a SIP voice network, we have some
examples in the docs:
Generic 64-bit, x86_64 Boards and Appliances
https://doc.astlinux-project.org/userdoc:documentation#generic_64-bit_x86_64_boards_and_appliances
Getting AstLinux running and functioning as a router/firewall/vpn is fairly
straightforward.
On the other hand, getting the PBX (asterisk) configured from scratch takes
some effort. We have tools to help configure phones and such, but getting the
first phone and upstream SIP provider configured takes time and research.
While PCIe cards that support FXO, FXS exist, some sort of SIP telephony
gateway device will also get you FXO/FXS with less trouble and more hardware
options.
An alternative to physical FXO, open an account with an internet SIP provider
and obtain a phone number and billing by the minute. Do the math, but is it
usually not expensive.
