@PIM41 Go to https://cockpit.swisscom.ch there you will also find the call filter under the menu “Call settings”
@Sophia_3700 theoretically it would be quite possible to outsmart your approach. However, the ‘attackers’ would have to know exactly the numbers of your contacts and then spoof them.
Technically, this would be possible via a dubious app. Imagine a ToDo app or a gallery app wants access to your contacts. If these are then misused by the malicious developer or simply resold for financial reasons, this quickly happens…
The opportunity is m.A. however very small.

Completely correct and functional! The most pleasant thing is actually to pick up and not open your mouth. Or if you speak several languages, use one that is not that of the caller. And if he asks you if you don’t speak French or something else: and NO unfortunately not. For sales calls in Spain on the national network I speak German only. The conversation stops as if by magic.
Hello everyone, since I installed the Filter there have been 0 calls on my cell phone but for the landline there is still a leak and since I found the trick if it is insurance because I tell them that I have my aunt who is in insurance and it works wonderfully. But also never say the word “YES” over the phone because they record you and then you are reached!!! Either speak another language or say that you are under guardianship… To the wise.
For insurers, ask what offers are available for those over 80. The effect is radical.
Another advantage of picking up without saying anything: if it’s a robot calling, it cannot formally mark the line as “interesting” and connect it to the call center. This equipment calls all telephone numbers in sequence without distinction. I receive calls on equipment that has numbers that are not known to anyone, neither human, nor machine, nor service. It is therefore not a targeted call, but from the collection of numbers who answer to resell them.
So why dont you AUTOMATICALLY put all Swisscom customers on this Call Filter service??
Hello @Leildoten71
Swisscom prefers to leave the choice to her customers to activate the Callfilter or not.
In addition, with the opt-in approach, more extensive blocking criteria can be applied according to the Swiss Federal Unfair Competition Act (UCA).
Have a good day
So what % of Swisscom customers want to receive these nuisance calls.
In Swisscom’s extensive analysis on this have Swisscom found this to be a high number? I would have that it was close to ZERO? Sorry but your answer is silly and makes no sense. Certainly not customer led? On a separate but related issue. Does Swisscom gain revenue from these nuisance calls?
thank you for the very interesting contributions 
it is absolutely necessary to read this article which will undoubtedly be able to shed light on the doubts raised 
Switzerland’s Ban on Geoblocking Enters into Force on 1 January 2022
22.09.2021
On 1 January 2022, a new Article 3a of the Swiss Unfair Competition Act (UCA) will enter into force, aiming to prevent unfair geoblocking and price discrimination practices against Swiss customers in distance commerce offers.
Background of this provision is the so-called “Fair Price Initiative”, which was submitted as a federal popular initiative in 2017. The initiative sought to prevent that Swiss customers have to pay significantly higher prices for goods and services compared to customers in its neighboring countries. The initiative suggested, among other measures, a ban on geoblocking to ensure that Swiss customers are not discriminated against when purchasing goods and services online (“shop like a local”). In response to the initiative, the Federal Council drafted an indirect counter-proposal. This indirect counter-proposal, as amended and adopted by Parliament, entails revisions to the Swiss Cartel Act and the UCA.
Under the new Article 3a(1) UCA, a person acts unfairly “who, in distance commerce, without objective justification, in relation to a customer in Switzerland, on the basis of his nationality, place of residence, place of business, the location of his payment service provider, or the place of issue of his means of payment: (a) discriminates regarding price or payment terms; (b) blocks or restricts access to an online portal; or © redirects a customer, without his consent, to an online portal version other than the one initially accessed”. This provision does not apply to specific service offers listed in Article 3a(2) UCA, such as financial services, healthcare services, gambling services and lotteries, private security services, and audiovisual services (e.g. streaming services).
Furthermore, the use of geoblocking and price discrimination practices shall not be considered unfair if there is an “objective justification”. It remains to be seen how Swiss courts will interpret this term in the context of geoblocking practices. A price discrimination may be justified, for example, if higher shipping fees or customs duties apply when selling to a Swiss customer. Also, geoblocking may be justified if a seller or service provider has (objective) reason to believe that its offering to Swiss customers would infringe a third party’s intellectual property rights in Switzerland, or other rights of a third party (e.g. under a trademark co-existence agreement). Geoblocking measures may also be permissible if an offer to Swiss customers (e.g. online offers of pharmaceutical products) would violate Swiss law (e.g. regulatory law).
It is noteworthy that the new Article 3a UCA only seeks to prevent discrimination against Swiss customers, but it does not impose a duty to actually ship goods to, or provide services in, Switzerland. It also does not apply in relation to discrimination of customers outside of Switzerland.
The EU already implemented a ban on private geoblocking practices back in 2018 (EU Geoblocking Regulation), which served as an inspiration for Article 3a UCA. However, there are differences between the two legal frameworks. For example, the EU Geoblocking Regulation aims to protect consumers and companies only to the extent such companies can be considered end users of the offered goods or services. The wording of the new Swiss UCA provision does not contain such limitations, but rather applies to all “customers” in Switzerland. This includes consumers and companies as end users, but also individuals and companies procuring goods and services for further distribution or processing.
Whether or not the new Swiss ban on geoblocking will have a significant impact in practice remains to be seen in the future. Article 3a UCA will have to be enforced before civil courts. In many instances, however, a Swiss customer will likely not initiate such civil enforcement action, especially against businesses domiciled abroad. While also Swiss consumer organizations or the Swiss government could seek injunctive or declaratory relief, it may be expected that they will only do so in selected cases.
Nevertheless, international businesses offering goods and services to Swiss customers are well advised to verify their compliance with the new rules under Swiss law.

Hello @Sophia_3700 thank you very much for your question, due to the problem you always have to be vigilant. The scams are becoming more and more sophisticated and are affecting all telecom providers around the world.
But maintaining contacts with a logo and photos is certainly a good idea. Kind regards, MirkoP

I do it similarly to @Alfi48
If someone calls me on the landline with a number that isn’t in my contacts, I don’t answer at first. I’ll then see what kind of person called me. If the number isn’t written down anywhere, it can’t be that important.
If someone calls me on my cell phone with a number that isn’t in my contacts, I don’t answer it, but I write a text message back with the message: “Who are you, what do you want? I only accept calls from numbers that are mine are known!”. Most of the time nothing comes back.
So far I’ve always done well, and the call filter takes care of the rest.
Am I on the wrong track or are two topics mixed up here?
First of all, it’s about spoofing, which means that instead of the dubious call center’s own phone number, a reputable one is transmitted as a CLIP.
“The display shows you a familiar number, e.g. the Swisscom hotline”
If the cell phone receives this number as the sender, the corresponding photos and additional information from the address book are also displayed, creating a false sense of security.
However, the countermeasures are those that help with unknown call centers that are marked as dubious and do not pretend to be otherwise (spoofing).
