[opensuse] Fritz!Box telephony in the US
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. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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. /Per -- Per Jessen, Zürich (4.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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.

Good point, yes.

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.

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.

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?

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.

Well, DECT does that today just fine. Three handsets, in two groups. Works very well. On one handset, I get two ringtones depending on the line.

Of course, that's always the case. Wol suggested DECT itself won't do it, but it will (when it carries SIP traffic). If you also want to benefit, you need a handset that supports it. (I presume "it" = SIP). We use a Gigaset C470IP with 2 x C430 and 2 x Cxxx (can't read the number anymore). The base station supports up to 5 handsets, Asterisk picks a handset and dishes out the ringtone depending on which number is being dialled. -- Per Jessen, Zürich (2.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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".

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.
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?
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 :-) - -- Cheers Carlos E. R.

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.

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.

Domestic ISDN no longer exists in the UK - ADSL over ISDN has never been available, so I suspect many people did what I did, upgraded to broadband and had to ditch ISDN. We're also moving steadily to FTTC (Fibre To The Cabinet), so a power cut to the street will probably take out the cabinet and kill the phone lines :-( New developments are FTTP (Fibre To The Premises) so they will be taken out by a power cut as a matter of course :-( (And of course, I can't get FTTC because I'm TOO CLOSE to the exchange.

Depends on the infrastructure. Cable systems offer phone systems via their DOCIS modems. However, the modem has a backup battery rated for 4-8 hours in case the mains go down.
I don't know whether it's changed, but I thought in the US you could take a mobile from one town to the next, and it would stop working.
Uh, no. There are 4 continental providers( AT&T, Verizon, Sprint, & T-Mobile) who generally have service within 10 miles of population areas(along interstates). I can use mine anywhere I have a Sprint signal and can roam usually as well. In fact, when most people move now they keep the mobile number the same and don't change it to their new area code. As for POTS(plain old telephone system), it's a national standard and the Universal Service Fund was designed for it and Power to ensure that all addresses can get both utilities(basically everyone pays for everyone to have access). Any phone sold in the US can work with any phone outlet. The 4 wire line only uses the Red/Green for the main line. You can use the Yellow/Black for a second line using the same wire. The reason US telcos want to get away from copper is that most wire servicing is done by union labor. That, and infrastructure costs more than a wireless signal in rural areas. In my area, there is a huge amount of homes with no access to cable or broadband. There are some WISPs(Wireless ISPs) but they are a slow & shared bandwidth system. One 3-10Mb/s access point can connect up to 200 users via 900Mhz or 2.4Ghz unlicensed. But, the more using it, the slower the overall speed. I get faster speed from my hotspot than my friend who is connected to a WISP. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not much use when it takes a couple of days to repair a line fault. IME power outages are rarely measured in hours. It's either minutes, or days.

Could you shove an, eg, Verizon SIM in your phone and connect to the Verizon network? I did get the impression things had changed, but I thought five, maybe ten years ago phones supported different standards and couldn't be moved between networks (contract phones here are usually locked to a provider, but that's software, not physically incapable).

Same - well, since about 1984. Before that, we didn't have phone sockets, they were physically wired into the network. But the GPO had to provide phone service to anyone, at a fixed price.
The reason US telcos want to get away from copper is that most wire servicing is done by union labor. That, and infrastructure costs more than a wireless signal in rural areas.

Here we have the new infrastructure companies rolling out fibre, so the old GPO (British Telecom) is being forced to upgrade to compete. We also have a big problem with metal theft, although they tend to target power rather than phone cables. Our most recent power outage was because thieves tried to steal a - I think - 250KV power line. It was THE power supply over a small river, and took out an area maybe four miles square. I think it took a week to repair. But, like with you, fibre is not being rolled out where the (private) companies don't think it's worth it. So decent broadband is clearly not considered an essential utility. Cheers, Wol -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Interesting. I had no idea that metal theft was a thing in Britain. I've seen it in the Mexican border areas, where railroad grade crossing gates don't exist because they'd be quickly stolen for the copper content. BTW, you mention that the thieves "tried" to steal a 250KV power line. They didn't succeed? If not, why? Did they survive? Why did it take so long to repair? Did a transformer need replacement?

Don't know any details. I think the cable blew up when they tried to cut it with a chainsaw. I had a previous experience, many years ago, that was similar. In that case, I believe the power cable was taking a lot more amps than it was meant to ... and when it got cut it shorted out horribly. That may well have only been a 25KV line, but most of our high voltage cables are three-phase, so if they short out an explosion doesn't sound unlikely - and it can easily blow up across its length so it ends up a LOT of cable needs replacing. Oh - and yes - metal theft is unfortunately very common. Mostly Eastern European criminal gangs come over here because it's not very well protected. Many churches have had their lead roofs stripped. War Memorials have their brass plates stripped. Power cables, train signal cables, etc etc. It's not as bad as it was because they've clamped down heavily on scrap metal dealers, but it still goes on ...

Here we have the new infrastructure companies rolling out fibre, so the old GPO (British Telecom) is being forced to upgrade to compete. We also have a big problem with metal theft, although they tend to target power rather than phone cables.

I think it took a week to repair.
Interesting. I had no idea that metal theft was a thing in Britain. I've seen it in the Mexican border areas, where railroad grade crossing gates don't exist because they'd be quickly stolen for the copper content.
It is an issue in Spain. Not metal in general, but copper. Some have died while trying to steal live lines. Often they steal the lines from street lines, that are underground. They cut the line at one end, they go to another end a kilometre away, and pull. Like tying it to a van and start it. The lights at the highway entrance to my city do not work since years, I believe the lines were stolen. Obviously replacing the lines is way more expensive than what they get. And they can also damage the tubing and other gadgets in the attempt. Of course it can take long to repair. I heard someone stole the catenary of a railway for kilometres. They can also steal the copper pipes from houses. The issue is diminishing, the police are getting more efficient at it. Like going for the scrape yards that buy it. One reason for going fibre is precisely to avoid the problem, but sometimes they cut the fibre to find out if it is copper. They are not engineers, after all. - -- Cheers, Carlos E. R.

Could you shove an, eg, Verizon SIM in your phone and connect to the Verizon network? I did get the impression things had changed, but I thought five, maybe ten years ago phones supported different standards and couldn't be moved between networks (contract phones here are usually locked to a provider, but that's software, not physically incapable).
There were 3 main standards in the US. AMPS(analog), GSM(AT&T, T-Mobile) & CDMA(Verizon/Sprint). You could sometimes switch a phone between carriers, but internet may not work. i.e. and AT&T phone on T-Mobile sometimes wouldn't work with data. Verizon and Sprint generally didn't allow switching nor had a SIM. Regs were changed about 15 years ago to start forcing them to do so. Now that most LTE phones that have a SIM(I have an old LG that's LTE but an internal, non swappable SIM), you can switch carriers normally so long as the contract is done and the phone is unlocked. iPhones are a good example.
But, like with you, fibre is not being rolled out where the (private) companies don't think it's worth it. So decent broadband is clearly not considered an essential utility.
Fiber is easy to install in urban areas like New York(although Verizon evidently reneged on something recently with the city govt) because you have a high density.

Not here. The installer told me to install my own UPS, which I did, of course :-( I know that recent installs are done with different hardware (mine has three boxes, the new has one), but I don't know if it has a battery or not.
I don't know whether it's changed, but I thought in the US you could take a mobile from one town to the next, and it would stop working.
Uh, no. There are 4 continental providers( AT&T, Verizon, Sprint, & T-Mobile) who generally have service within 10 miles of population areas(along interstates). I can use mine anywhere I have a Sprint signal and can roam usually as well. In fact, when most people move now they keep the mobile number the same and don't change it to their new area code.
You can roam now because they adhered to GSM, which is an European standard (pushed by the governments). Before that, from what I knew it was not possible to roam (no such concept), the systems were not compatible.
As for POTS(plain old telephone system), it's a national standard and the Universal Service Fund was designed for it and Power to ensure that all addresses can get both utilities(basically everyone pays for everyone to have access). Any phone sold in the US can work with any phone outlet. The 4 wire line only uses the Red/Green for the main line. You can use the Yellow/Black for a second line using the same wire.
POTS is almost an universal standard, the differences amongst countries are few, mostly on other areas (like call tones). It meant that an old phone from Graham times would still work on a today exchange. In standby the exchange supplies 48 nominal volts DC (actually more because lead acid batteries supply more, so rather close to 56 volts). When ringing it switches instead to an AC voltage that, from memory, is about 60 volts, Maybe 90. With an stablished voice connection the DC voltage dropped a lot, but was still enough to feed some electronics.
The reason US telcos want to get away from copper is that most wire servicing is done by union labor.
I doubt that, because they are doing the same on other countries that have no USA style unions, like Spain. There are many reasons, but basically they mean they get more money :-) - -- Cheers, Carlos E. R.

Actually, it was LTE not GSM. My LG has LTE & CDMA tho. I can't switch to AT&T and use their 3g/GSM. Also, older LTE phones use different bands. Verizon uses 700Mhz and Sprint at 1900Mhz, etc. Anymore it's cheaper for a phone to have all the LTE bands than not, but 2G/3G can still be an issue for when 4G is too weak. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't think I've quite understood your setup, but to compare with my own - the router needs power, it's on the UPS. Asterisk needs power, it's on the UPS. The switch in the house needs power, has no UPS. The DECT base station needs power, has no UPS. If we have no power, we have no telephone - other than the mobiles.

Ok, I'll try to explain. The fibre from the telco connects to a device called ONT (<https://en.m.wikipedia.org/wiki/Optical_network_terminal>). This device has a connector (RJ11?) that provides the POTS alike service, and an ethernet connector. The phone connector from the ONT is connected to the phone input of the DECT base, giving analog phone service to the house, and also to the old copper pair inside the house, although I do not use it. I think there is a separate bell near the patio. It is of course disconnected from the street copper pair. The ONT should be designed with a battery (included or optional), but it is not. The ONT obviously handles the SIP to phone conversion. I have no access to it, no configuration interface appears on the LAN, I think. The ethernet connection from the ONT goes to the router, which has the typical 4+1 mouths. One of these goes to the TV desco, another to my switch on a different room and floor. The router also has a phone output connector, which is not used in the currently ISP suplied configuration. The TV desco connects to the router on eth, and also to the digital TV antenna on the roof (IIRC), which is not used. Has an hdmi? output that goes to the TV set. Finally, there is a TV set :-) All those gadgets, including the TV, go to the same UPS. All of them, because the UPS sits on the floor at the side of the cabinet, and there is a single AC mains cable going into the cabinet. The switch and WiFI AP are on another room with the computers, so they get a different UPS. The router has its own WiFi AP, but I disabled it (bad coverage). Currently the ISP replaces ONT + Router + TV desco with a single box. So much fewer cables and AC power suplies.

Standard landline phones in the US are supplied power from the exchange: -42 volts, I believe. The ring signal is something like 25Hz AC applied on the DC lines at about 90 volts.

Dunno 'bout across the pond, but in North America, phones have used central office power for over a century. The CO provides -48V DC, nominal, actually close to 56V (on hook) to the phones.

That's the old style cable. Many years ago, they switched to 3 pair CAT 3 cable, with the phone on the blue/white pair. Incidentally, there was a network called StarLAN, which was designed to run on the other 2 pairs of the phone cable. StarLAN became the basis of 10baseT Ethernet. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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.
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
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.
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!
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.
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!

The Canadian system isn't as price-aggressive as the USA, but our system does 'work anywhere', for some values of the provider. The Big Three, Bell, Telus and Rogers, are truly national. The second tier are either aligned with (aka bought out by) the Big Three, (g.g.Fido) and are similar. The real second tier, that is those that still claim (some) independence (e.g. Freedom Mobil) only operate in and around the major cities. The 'around' is very liberal. Freedom's idea of 'Toronto' is basically the Golden Horseshoe round from Niagara/StCatherines, up with a sideways detour to Guelph and London, past the greater Mississauga, the Greater Toronto Area, a detour north to Newmarket and Barrie, then across past Scarborough, Ajax, Oshawa, Bowmanville, then north to Peterborough. This is the industrial and financial core of Ontario (and at a better then 60% level, or Canada). The population of the GTA is about 6.5 million; the aggregate of this coverage would more than cover that, getting on for perhaps 15 million. That covers a few dialling code areas :-) https://en.wikipedia.org/wiki/List_of_Ontario_area_codes WHAT WE DO NOT HAVE ... is a reduced price/reduced coverage option. I can't, for example, say that I want only to dial 416, 647 and 437 and pay only 15% of what I currently do. Anyway, dialling most of the GTA is a 'local' call as far as the Big Three telcos are concerned.

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

Well DUH, I have that anyway with my Android phone to my service provider anyway. It's part of the Android set-up sine neverwhen.

What I was speaking of was completely without any cellular service. That is, when I'm home, the Fritz rings my smart phone over wifi.

In the US you can try using Freedompop. They offer 200 minutes, 500 texts, and 200(AT&T phone) or 500MB(Sprint) data for free each month. I have one I use for Craigslist.

First: As someone pointed out you need a service provider of some sort to provide the connection to the world wide telephony system. This lets you map a phone number to the mechanisms discussed below. Please note: I'm perfectly well aware that you can do this yourself with additional hardware running Asterisk https://www.asterisk.org/ and connectivity yourself, in effect being your own service provider. People do that. It is not a minimalist solution. As I've mentioned, I make use of voip.ms but there are other service providers. Every trade show I go to there are the latest fly-by-nights. Some seem to last longer, some make it to google: http://landing.thinktel.ca/SIP-trunking/ Google for those nearest you, but do check out voip.ms for comparative cost. Second, given that you have an internet based VOIP service, please realise that service is accessible ANYWHERE you can get internet connectivity. This might be: - at home, wired - at home, wifi - at a friends house, wifi - on the street using municipal wifi if your city supports that - at Starbucks or any number of coffee shops or restaurants that supply wifi - in the waiting lounges of airports and train stations where wifi is available - in libraries - in pay-for-use internet cafés Given connectivity you might take any one of the following options: at home, I have an internet/Ethernet connection from my cable router to a Linksys ATA box that cost me $35 at a local store. That has a regular RJ45 plug. I can either plug a standard phone set into that or connect it to my existing household phone wiring (after disconnecting at the connection to the Bell wiring into the house) and have the phone service at all the regular phones though the house. at home, my cable router also handles wifi and I can access the service provider for phone calls from any device that has wifi: my Samsung phone, my tablet, for example. With my phone I can configure it so that the dialler that is built into that handset can also make voip calls over wifi. https://www.youtube.com/watch?v=bJ9lOp5L7sU I have mine set to 'ask for each call'. Strictly speaking, you don't even need a service provider for you cell phone. You can use the wifi-to-SIP alone. That is what I do with my tablet. I run Zoiper, https://www.zoiper.com/ one of a wide number of VOIP applications for Android, and I believe it runs on other platforms PC/Windows, PC/Linux, PC/OSX and IOS. My tablet does not have GSM or LTE - NIX. only wifi. By using Zoiper and my voip.ms account I can make calls from anywhere I can get a wifi connection. That included the town hall of a small town in rural Wales[1]. So it you want to be minimalist, the least hardware you need is that free 7" tablet that the bank gave you when you signed up for an account. All the rest is software. OBTW: if your service provider cooperates you can send SMS TXT messages over VOIP. [1] Although I was using the London node so as to eliminate echo, to the people I was calling in Toronto it seemed as if I was calling from home. no long distance feel to the call.

Whether or not you run Asterisk, you still need a connection to the telephone network. (provided you need it). If you don't need the telephone network, you can still call peer-to-peer.

That is a big "if".
