Landline telephony IP - questions and answers

Hello everyone

In mid-March, I informed the media together with our head of technology Heinz Herren about the planned replacement of TDM telephony (conventional technology for telephony: analog standard) at the end of 2017. This has led to many questions. I would like to answer your questions for the private customer market here:

A few facts first:

Swisscom will definitely support conventional landline telephony by the end of 2017. Anyone who only wants a landline telephone connection today can order this offer until the end of 2017.

Swisscom has decided that all customers who order a Vivo Casa will be switched to IP landline telephony. We will only offer new product offerings together with the new IP fixed-line telephony. Exciting offers await you in 2014!

Landline telephony IP from Swisscom is not internet telephony like Skype is, for example. Although we use the IP protocol, calls within Switzerland run over Swisscom’s own network. If a customer from another provider receives a call, the call will be forwarded via the usual channels.

The router is the central element for all our services (voice, Internet and TV). Therefore, the router must always be on in order for the services to be used. We are working on being able to offer other devices in addition to the new Internet box in the future.

Router and energy consumption: Since 2012, the customer’s power consumption has been improved by 50% in all new TV boxes thanks to a low power mode and in the latest generation of routers, which has been available from Swisscom since the end of 2013, various power saving settings have been integrated that make it possible Allow users to permanently or temporarily switch off unneeded functions, such as WLAN and network functions (NAS). And for someone who just wants to make phone calls, there will be an extremely small, energy-saving solution, for example. Calculations show that by replacing conventional technology with IP-based landline telephony, the overall energy balance is positive.

Do you need an internet subscription to be able to make phone calls after 2017? No. This means that the customer has a broadband connection, but only the IP fixed-line telephony service is activated. Since no internet service is activated, you don’t have to pay anything for it.

The advantage of landline telephony IP is, among other things, significantly improved voice quality when a conversation is conducted between two telephony IP connections and the end devices are IP capable. We will be offering several new IP-enabled devices in the near future. At the same time, we are working with other manufacturers to find solutions so that third-party devices are also supported.

Restrictions today: Today there are certain services such as alarm systems or lift telephones that rely on TDM telephony. Since the switch to fixed-line telephony IP is a global trend, the manufacturers of such solutions are working on replacement solutions that are IP-capable.

Schindler already has more than a thousand lift systems in operation that run via GSM/SIM cards (machine-to-machine). OTIS Switzerland is in the pilot phase. Several alarm system manufacturers already offer IP-capable alarm systems.

Owners of such services should therefore contact their solution seller (supplier) and ask for an IP-enabled version.

Existing landline telephones: All telephones that support frequency tone dialing can continue to be used by connecting them to the router. These devices do not achieve improved voice quality. ISDN telephones are no longer supported and therefore cannot be used.

Customers with an ISDN-Anschluss also receive landline telephony IP and can continue to receive multiple numbers and voice channels with the Multiline option. To do this, they are migrated from an ISDN Anschluss to an analogue Anschluss. Therefore, in many of these cases, the house installation needs to be adapted because ISDN uses special cabling. In this case, Swisscom requires the use of a technician.

Can multiple telephone sockets be used in the house? If a so-called BBR (broadband ready) installation already exists: Yes. If not, the house installation can be adapted at the customer’s request and for a fee. However, we recommend switching to our new, cordless IP landline telephones, which can then be connected directly to the new Internet box, for example.

Hello GuidoT,

I have a question about the VOIP service features:

What about these service features? Is there anything planned (RES/SME)???

1.Callback when busy (CCBS)

2.Callback for failure to report (CCNR)

3.Three-way conference (3PTY)

4.Tariff information during the connection AOC-D (important for telephone billing for PBX solutions)

  1. Tariff information at the end of the AOC-E connection (important for telephone billing for PBX solutions)

  2. However, sipgate has expanded the function of the ‘call forwarding’ service feature. Instead of only offering one forwarding destination, as is usual in the landline network, the VoIP provider provides three call destinations. Incoming telephone calls are then forwarded in the sequence of the stored telephone numbers and the defined time interval until the call is accepted.

7.Another function unknown in the landline network is the ‘parallel call’. It causes incoming calls to reach every telephone connected to the VoIP Anschluss. Their locations - whether at home, in the office or on the go - are irrelevant. The call is made wherever it is answered first.

Swisscom’s landline telephony IP is not internet telephony like Skype is, for example. Although we use the IP protocol, calls within Switzerland run over Swisscom’s own network. If a customer from another provider receives a call, the call will be forwarded via the usual channels.


How is this to be understood: the SIP connection (n-Stack) goes via the IMS or Centrix system and then to the p-Stack (TDM) (within Switzerland, however, the connections run via Swisscom’s own network)?

or via Metronet?

Is HD telephony between GSM HD and VOIP HD planned, when???

Unfortunately, since none of you Swisscom members could answer these questions for me, I’ll take this one now

opportunity was.

Hello
Thanks for the questions. If I have some questions, I first have to ask my colleagues from IT and Network. But I’ll do it today. In addition, I can only answer questions about private customers at the moment. But I will draw the attention of my SME colleagues to your questions. Give me a little time and I’ll write the answers here.

What I can already say. We will enable HD conversations between landline IP and mobile. However, this will not happen until 2015 at the earliest. But it’s on our to-do list.

We will also add some functions in May. We plan to continually develop the service further. But it has to make sense. We won’t build features that only a few customers need. It is a mass market product for private customers. I won’t publish an exact list until May because I don’t want to promise anything that won’t come by then (there are always reasons that require short-term changes).

I don’t think it’s relevant how the conversations technically flow through the systems. From my point of view, it is important for the customer that the calls do not take place over the normal Internet, as with Internet VOIP providers, but only in the protected Swisscom network. If a Anschluss from a competitor is chosen, it will be treated in the same way as today. But I can also ask here how it works technically.

And while we have question time… in the future power customers like me (still ***** with ISDN)

get the data for VoIP (SIP login data)?

Only then would it make sense for me to switch to AllIP, since I have a Fritz!Box for telephony

use (now mixed ISDN and VoIP externally and ISDN/DECT/Analog internally for fax) and connect it to Swisscom

Router hangs.

I would tear my hair out if I then used the analogue connections on the Swisscom internet box

would have to connect (modern - antique - modern) and would have to lose the convenient functions of VoIP.

Thank you and have a nice day

Clear questions, clear answers:

At this time we have no plans to release voice service login details. Why not? We are not a VOIP provider over the Internet, but our voice service must have the same service quality as the old TDM telephony (or ISDN). But we are conducting a study to determine what conditions we need to create so that we can release the data. Second point is security. Even if I point out the risks to every customer who receives the access data and have them sign, problems will still arise in case of doubt. We are currently preventing this in the interests of our customers.

You can share these arguments or not. At the moment that is our view.

You will be able to use ISDN until the end of 2017. I can’t say today whether you can use a VC for that long. As a private customer, you will no longer receive new products on ISDN. And maybe you really want to get rid of ISDN this afternoon 😉

Which VOIP convenience functions are you missing?

Show original language (German)

Thanks for the quick reply…

Of course the security risk is higher (although a lot of not uncritical data can be obtained via the Kundencenter) because you can also mess up via email if you use it (e.g. to get bank details or other login details with Fishing). but it doesn’t cost as much money as telephony (although if someone plunders my bank account it will probably be even more expensive).

Well, I would miss HD voice (if I have to connect my Fritzbox to the analog port on the Internet box), conference (with some VoIP there are more than three) and above all the fast dialing and the fast signaling on the device with number and names (which I only got after 1-2 rings with analog and IMMEDIATELY with ISDN).

In addition, with the Fritzbox I can still keep my “expensive” comfort ISDN telephones internally.

Or will Swisscom give me two or more Siemens Gigaset DX 800s (now I have the DX 600 purely ISDN)?

And, I can make internal calls from internal ISDN / Dect.

Sorry, I’m just one of 100,000 customers who doesn’t just install themselves with the otherwise good 08 15

want to be satisfied with the solution. But I also understand that Swisscom is only for me and the “ten” others

Techheinis can always provide the extra solution straight away.

Swisscom (from good experience so far) has always had an ear for us.

I also lose emergency operation security, because even with ISDN I can still make calls without electricity using an emergency authorized ISDN device (remote power from Swissom as with analogue).

I don’t know how long it runs, but without the diesel unit it works for me after 5-10 minutes

AllIP is over, the UPS in the cupboard won’t last any longer, for routers, switches, Fritzbox etc.

Show original language (German)

Please. 🙂

There are always risks. That’s so. But at the moment we don’t want to contribute to increasing this.

Thankfully, power outages in Switzerland are very rare. We see that most customers then switch to mobile. But yes, there are also disadvantages to modern technology.

Yes, ISDN phones are a problem. These definitely cannot be used any further. But there will certainly be offers in the near future that are just as convenient. I can’t say more yet. It will probably take another 1-2 years. The market is in transition.

Hello,

I’m also someone with ISDN, it was touted as the technology of the future when we were building a house in 1996 (which apparently will no longer be the case in 2017), and back then I had the advantage of being able to surf the Internet and make phone calls at the same time ( which wasn’t the case with analog back then, but is today).

In connection with the possible switch to Swisscom TV 2.0, the question naturally arises as to whether there is a way to still be able to use the existing cabling (ISDN NT)/existing ISDN sockets, or the various ISDN devices in the house. Now my ISDN house cabling is connected to a VDSL2 over ISDN splitter (and then the ISDN-NT1+2 a/b box), what about the new box? Could you attach an IP-capable device that would then continue to feed the ISDN system (Fritzbox?)? Or can/must we use the two analogue connections that we still have in the house?

What about IP telephony? Are two parallel calls possible like with ISDN, or are we going back to the time when one person who made a lot of calls could block the others?

What does the offer for IP telephones look like? Do they also have radio telephones that can be connected to each other (house telephony, up to 6 devices)?

Before I actually switch from ISDN to IP, questions like these are still relevant to me.

With IP telephony you can operate two independent telephone numbers.

Menno, what kind of UPS do you have there? Mine only runs for 15 minutes if things go well…

I have several spread out around the house so I can keep the voltage constant, one is at the link below.

Since we’re still doing film editing, it’s not a big deal if the fuse goes out and since not every room in the apartment has its own fuse, a problem quickly arises.

http://www.steg-electronics.ch/de/article/apc-br1200gi-493383.aspx

The high wattage is only required for a short time when switching on, because some UPSs still have a PC and iMac connected.

N.B. There are also cheaper ones in the color white which are tip top for normal requirements.

Yes, I also have those in the box, for the Swisscom router, 1 small 5 port switch and the Fritzbox and the NT2AB but after 15 the power is out…

I still have a 2000 on my PC, which is about 10 minutes later (PC shuts down after 5 minutes)

But I still have an i smartphone… and the Swisscom cells are supposed to last another 1-2 hours (maybe

I’m lucky because my cell is on the telephone switchboard and they definitely have a big one

Diesel in the basement) or I go straight to the telephone exchange on the other side of the street (but there is

probably no staff left to open it…) smile…

In my case, only the Swisscom router and the IP telephones are connected to a UPS and they don’t need that much power in the event of a power failure. The IP handheld telephones also have a built-in battery and it lasts for several days either way.

2 different numbers is not the point of the matter, or only for external phone calls. With ISDN you can also make 2 phone calls at the same time on the same number, ie. someone calls us on the main number, and while the call is still in progress, someone can call the main number again and the call can be answered at the same time. Does something like that work with IP too?

Show original language (German)

With AllIP I will attach the two AB ports from the Swisscom router to the Fritzbox 7390

the 1st completely normal AB-AB and the 2nd with a Bbox from Auerswald to the internal port (although it is a

crap, but works great). So I can continue to use the internal fax from FB

and I also have the ISDN telephones and a DECT network on the internal S-Bus and on the 2nd internal AM

I can also send faxes from the multifunction printer.

Show original language (German)

Thanks. At least there still seem to be options instead of having to replace all ISDN telephones.

Most of our ISDN telephones are radio telephones with the DECT standard, so you can even register them with an IP base station. We only have one ISDN fixed telephone, fortunately, and the ISDN base station is also “for Lau”.

Or then there is the route via Fritzbox, and the entire ISDN house line depends on that, so I have to investigate further.

My only “worry” is whether it will still be possible to make two simultaneous phone calls (to the same number) with IP. I would find it difficult if that no longer worked.

This is still possible with the MultiLINE option.

I can tell you in a week… I think it could work with two Roussau, on the analogue

Maybe port too… but I can test that in a week

No, two Rousseau alone are not enough. Also in connection with the analog port on the router.

Only with the MultiLINE option are two connections possible at the same time.

I tested it a long time ago…
