i.e. a box where one plugs the telco line into one end and their home
phone system into the other end and which provides at least the service
of an interactive announcement: "Press 1 for Sue, Press 2 for Dave,
Press 3 for Paul......".
Nice-to-haves would be some sort of scalable call acceptance where
callers with certain IDs get routed right through to a specified
extension without hearing any announcement.
Is there anything like that currently available?

Per (PeteCresswell):
That being the case, the device in question would not need to serve
multiple extensions.
The "Press 1 for Sue, Press 2 for Dave, Press 3 for Paul......" is just
the challenge part. Really, there would be only one key that does
anything - buried at the end of the prompt.
A strong nice-to-have would be that the phone never rings if somebody
presses the wrong key, but that they would be offered the opportunity to
leave a message.

FWIW, my real agenda is to add challenge-response to my home phone.

In article <fb9gn8t43ia8ii5sl...@4ax.com>,
The generic answer is: Linux PC running Asterisk.
There are several turnkey installations avalable. Start googling!
freepbx, pbxinaflash and many others...
There are also many paid-for ones, but they're not as flexible as the
free ones ime.

Hexadecimal dial? Even 4 column DTMF only goes up to "D".

You will need some hardware with an FXO port for your landline. My
system uses only VoIP trunks, I might try adding a GSM trunk because I
think I have a compatible USB dongle that someone has written the code
for.
Total outlay, about $54 and almost negligible running costs.
Has the Raspberry Pi made as much impact in the US as it has here?

Per R. Mark Clayton:
this issue.
Given that their "TrueCall" black box can front-end an existing
handset system, that's a Good Thing.... as opposed to having to shell
out for each hand set.
I like the "Do Not Disturb" mode - assuming it has a timer on it and
does not have to be manually reset.
But it seems to fall short.
To wit:
- It only ignores blacklisted and "Unavailable" numbers. The robocalls
and solicitors I get on my cell phone almost always supply a number.
Being too cheap to pay the extra for CallerID on my land line I don't
know for sure about the calls we get there... but it seems reasonable
to assume it's the same situation.
- Per http://tinyurl.com/c6dx24a
"And it’s worth noting the TPS cannot stop calls from
international companies or from companies that choose to ignore
the rules."
Based on the lame-sounding letters I was getting from
the Pennsylvania (USA) attorney general's office in response to
reported DNC list violations, I suspect that most robo and solicitor
calls are international and made via VOIP providers.

If you could, you'd probably be pushing the limits of the CPU.

Truecall will do that, I think.

You can set a 1, 2 or 3 digit pass code which trusted callers can use
to get past the device. Other callers can leave a message.

Not really, if you chose your codec carefully. A Winmodem is essentially a

DAC/ADC in a box, with a relay for switching on/off hook. So all you need
to do is keep it filled with 8KHz audio - that's 64kbps in each direction.
If you're encoding simple formats like a-law or u-law you should be fine - I
agree that trying to do GSM or ADPCM could be more CPU intensive (but the
GPU may come in handy here). I've done a-law/u-law on a 233MHz 32MB MIPS
router, while GSM transcoding was a bit much.
The trouble seems to be the relative paucity of USB modems these days -
there are plenty of PCI winmodems, but not so many USB.
<further digging ensues>
It looks like Smartlink USB modems, like this one (probably vendor:product
0483:7554):
http://www.tmart.com/56K-USB-2.0-Fax-Modem-External-Dial-Up-PCI-Voice-V.92_p97534.html
have a Linux USB driver (sl-modem-source package in Debian/Ubuntu).
Some Smartlink AMR/PCI drivers support ALSA, but this one doesn't. However
it makes a very simple device /dev/slusb0 to which you can read and write
audio samples, with an ioctl for setting sample rate and on/off hook.
So it probably wouldn't be hard to plumb this into a console channel in
Asterisk to get a cheap FXO port. Echo cancellation might be an issue, I
don't know if Asterisk handles that. I'd hope Asterisk would do DTMF
en/decode, but worst case you could pulse dial with little effort (or simply
play back stored samples for proper DTMF).
There might be a way to hack it into an FXS port too (use the hookswitch
relay to switch ring current, or something).

No. It's about 90p cheaper.

Your argument is going to be that the OpenVox card is not decent,
but I've installed dozens of them and they're fantastic and I've had
better support from then than from Diguim. Combine them with the Oslec
echo canceller module and I hve not found anything to rival them.
Not applicable for the Pi though, but if you already have a PC running
with a spare PCI slot then it's a no-brainer.

No, it wasn't the OpenVox card I was thinking of (I wasn't aware of it).
