I didn't know there were any tape-based units still being made. I've been using
a PhoneMate for almost 20 years, and I like it fine.

The prolem with many "digital" machine (including mine) is that the
greeting, and the incoming messages sound like Darth Vader's voice.

"Luke, I am your father. Do we need milk?"

This is compounded by the use of cell phones.

I've heard a couple of cases where the digitized message contained a
codec artifact that my cell phone codec could not deal with. The
message played to that point, then was garbage from there on out.
Locally, or from an analog land-line, there was no problem.

Once you get compression down to 7200 Hz 2-bits adaptive-whatever-law,
if the audio makes a change the math can't deal with, sync is lost forever.

I think this utter crap goes under the fancy name of Linear
Predictive Coding, which does SERIOUS compression of a phone audio
signal. To call the sound robotic is an insult to talking robots
worldwide. Whenever I hear it I start lusting for a +/-6dB 300-3.5k
response analog line.

If you want a standard Phillips cassette-based answering machine,
you have to cruise the thrift stores and yard sales, or if your time
is better invested elsewhere, hit ebay.
Failing that, what's wrong with using an old PC for an answering
machine? Other than it being a collection of largish devices (metal
box, 13" monitor, and keyboard and mouse dangling someplace), the
power supply fan making noise, and it taking maybe 50 to 100 watts
(with monitor off) just waiting for a call, vs. 5 watts for a dead
quiet answering machine.

Absolutely true for the 2.4 kbps Inmarsat stuff we were using around 1990. Pretty true for the vast majority of 10kbps stuff we've been living with over the past decade. Marginally true for the 12kbps stuff we've seen over the past 5 years or so. Not true at all for the newest high bandwidth stuff which will probably become the next generation's "toll quality" benchmark.

Hi folks,

I have to replace an answering machine. tHe all digital ones I hear
seem to sound like utter garbage over the phone. SUre wish they made
the old type with the endless loop cassette and the regular cassette
to store the incoming messages.

NO folks, not going to put a windows PC and sound card on voicemail
duty, looking for a stand alone box.

WHo's having good luck with what out there for tape based units still
on the market? REmote access would be a plus but not necessary.
Audio quality does matter to this old grouch however.



I went to a voice mail service through the phone company a couple years ago.
Best $5/month I've ever spent. Once it's set up I don't have to fool with it
& nobody gets a busy signal. It sounds like the phone sounds AFAIC.
YMMV
