Fritz!Box telephony in the US

ken
While hoping that the FCC doesn't kill network neutrality, I'm thinking
about setting up VoIP at home to kiss my monthly phone bill good-bye. 
I've read up a bit on the router made in Germany called the Fritz!Box
which purports to include in it the hardware and software and that it
will work with US phones (the old, standard landline phones every
American over twelve should have seen).  Does anyone have first-hand
experience using VoIP with the Fritz!Box in the US?  I'm considering
their model 7590.

Thanks.

Hi Ken

you don't need a Fritzbox or similar to do VoIP, but you do need a
provider to connect you to the regular phone network.  To hook up a
plain analogue phone for VoIP, all you really need is a little
converter (often called "ATA") box a la  Linksys SPA112 or the
Grandstream ATA-486.  If you going to talk to the rest of the world,
you pick a provider and they'll give you your SIP credentials to
configure the box with.  

The Fritz 7590 will do analogue telephony too, but I seem to remember
something about the wiring in a US phone being different.  Not a big
deal IIRC.

I don't remember Canadian POT phones (which are the same as USA phones, I
believe) being different from Spanish phones. The system on UK was
different, because they separated a ring wire - at least when I looked
decades ago. There could be other subtle differences, specially regarding
modems.

Cordless phones are currently different, yes (DECT).

Good point, yes. DECT is worldwide now, but the frequencies in the US
are different.

Correct.
My local phonecos, Bell and Roges who took over from Sprint some while ago,
rovided this service but I found it was comparatively expensive.  Other
intrernet providers that lease cable capacity from Rogers offer a voip service.

But the independents who specialise can probably give you the ebst rates.

I use  VOIP.MS
https://voip.ms/en/rates/international

Depending on your location and local legislation you may have number mobility.
It applies where I am and I kept the same number in all my dealings with Bell,.
Sprint, Rogers and now voip.ms.

When I signed up I also decided to take a  new business line number.  They asked
me where I would like it to be "local" to, Toronto, New York, Los Angeles or
London, Paris, Berlin?  Same price.  They have nodes all across north America
and western Europe

I have the Linksys at home.

I also have a voip app on my cell phone and tablet.
And voip.ms has nodes, as I said, all across north America and western Europe.

Heck, If I'm in rural Wales visiting a relative there and visit a coffee shop
that has internet service I _could_ make use of the Toronto node, if I forgot
the London numbers, using my Android tablet and Zoiper, but there would be a bit
of delay/echo from crossing the Atlantic back and forth!

I was astounded to find that the rate with voip.ms for calling my relatives in
the UK/landlines[1] was the same as calling locally.  Forget LD plans!  Heck,
it's the Internet for ${DEITY}'s sake!

[1] Trying to call UK cell pones is a mess!
But then compared to the North American system the UK phone system is and always
has been a bit of a mess.

My telephone company is giving me "fake" POT: it is VoIp behind the
scenes. Some people manage to find out the SIP configuration details and
use it. But then the ISP changes something and stops working for a while.

Why? I'm curious.

Swisscom does the same, but have agreed to make the SIP credentials
available if people ask.

That's true, there are a number of those ATA boxes.  There are a few
features, though, which sell the Fritzbox ahead of them.  One is that
the Fritz is an integrated unit-- with others, e.g., the SPA112, I lose
a LAN port (already in short supply) and need yet another mains outlet
(with room enough for a power supply).  Fewer cables is always better. 
Secondly, and much a selling point for me is that with the Fritz I can
connect my smart phone because the Fritz has wireless built in... in
effect the smart phone becomes a DECT except that it also works wherever
the phone gets internet, whether at home or across the country.  Third,
all of the features are integrated together and all difficulties I might
have go to the same tech-support number.  I've found all too often, and
all too painfully, that when I have two or three different
products/units all needing to work together, their different
tech-supports play hot potato with the problem... each separate
tech-support monkey simply, continually blames the other
product(s)/units(s) for the problem and the problem is never resolved. 
Gimme instead one tech support call for the whole appliance, all the
software and all the hardware.

Right.  I'm also looking for recommendations on that service from the
Noble Group Mind.

Yeah, the sketchy docs I've read say (I think) that there are two
flavors of POTS, Annex A and Annex B.  This is configurable in the
7590... so I've been told.

Annex A and Annex B (of ITU-T G.992.1) are about the ADSL "flavour".
annex A is for plain POTS, annex B is for ISDN.

True.  There are about eight different bands used in different countries
throughout the world.  I've had lots of different cordless phones, but
never used a DECT phone.  Maybe I'm missing something, but I don't see
the point in DECT phones anymore if a smart phone can serve the same
purpose.  (?)

It has some of the functions of a smartphone, but connects only to the
house POT line.

It is a cordless phone, but follows a standard.

In the US, although there are typically four wires in the cable going to
the house or business, POTS uses just two of wires (the red and the
green), one of which is the "tip" and the other the "ring".  I had ISDN
in my house for a while and even then only two wires were used... but
that was probably on the "smaller" ISDN protocol.  Does the UK use three
wires...?  or all four?

Same in Spain, although I have never known the colours or names. It is just
the two middle ones of the connector.

I think some homes used one of the other wires for some house purpose,
probably related to internal calls or transfers.

I have also seen cables with only the two central wires.

The line to the house had two wires, as everywhere, but at the House there
was a box with a capacitor, to separate the ring signal on a third wire. I
don't know if this was everywhere, but the British magazine I followed
certainly described this wiring. I don't know the reasoning, either.

That meant that the phones could omit the internal wiring to separate the
bell, and thus, could not be used outside of Britain.

I hope someone can confirm or deny :-)

There is some truth in that, I've wondered about doing it for a while,
but it's not as convenient.  For instance, we have 2 handsets for the
home# - can I make that ring through to two smartphones, pick one and
the 2nd one will stop ringing?  I would also want my office phone to
ring through to my smartphone, but with a different ringtone.

I think the issue between US and German phones (maybe others too) was
the wiring in the RJ11 plug.

The external wiring up to the terminator box is only 2 wires, but the S0
bus needs 4 wires.

Which means that, unlike the early cordless phones, any DECT phone will
connect to and provide basic phone service over any base station. I've
done that, connecting handsets from one manufacturer to a base station
from another.

In the early days of cordless phones, they only worked with the base
station they came with.

DECT won't do that. The base station will cause all handsets to ring,
and answering any handset will stop all the others from ringing. There's
no way, to the best of my knowledge (and I have tried) to connect one
handset to two base stations simultaneously.

At least one UK line provides power - our phones are designed to stay
working even if the electricity supply to the house is cut. How it
actually works I don't know - I believe it works at 50V.

Same in most places.

Here it's usually up towards 90V.  Anyway, yours will probably go away
too - in Switzerland, residential lines using analogue and ISDN are
being turned off in two weeks.  All migrated to VoIP.  Germany is
taking a little longer, and I expect it'll happen in the UK too.
