All your questions on Pro Office.

Can I set up guest Wi-Fi?

Yes, you can have two Wi-Fi networks, one for your business and another dedicated to guest Wi-Fi.

Can I connect my payment terminal?

Yes, you can connect your payment terminal to the Fiber Box via a LAN or Wi-Fi connection.

What is a Wi-Fi Box extender?

The Wi-Fi Box extender allows you to increase the coverage of your existing Wi-Fi network, while keeping its parameters perfectly identical: network name, Wi-Fi keys, etc. By placing it in a proper location, your Wi-Fi Box extender will optimise the reception and quality of your Wi-Fi on all your connected devices.

How can I reach 10 Gbit/s?

To achieve maximum speed, the following conditions must be met:

  • a cable connection via LAN (Wi-Fi being limited in speed); 
  • use of the 10 Gbit/s port on the Fiber Box;
  • a device compatible with a speed of 10 Gbit/s

If all these conditions are met, you can achieve speeds of between 7 and 8 Gbit/s in both directions. The advantage of 10 Gbit/s is that it allows a very large number of devices to be connected to the internet at high speed, rather than just one device at maximum speed.

I already have a fixed IP address; will it change when I switch to Salt?

Fixed IP addresses are not transferable from one operator to another; therefore, it will change.

Is my existing phone compatible with Pro Office?

All certified DECT handsets (CAT-iq.2.0) are compatible with Pro Office. In addition, all RJ11 (analogue telephone) devices are compatible with Pro Office and can be connected to the FXS port of the box. SIP phones (RJ45 devices) and older ISDN phones are not compatible.

Do you provide voicemail?

Yes, our Pro Office service includes one voicemail box per phone number, i. e. 5 voicemail boxes. To activate it, go to your customer account, under «"Subscriptions»", click on a phone number and then go to the «"Voicemail»" tab. Then carry out the activation. You can change your access PIN and set up your mobile number to receive call notifications via SMS.

At Salt Business, it’s all about trust. 

What our business customers think about Pro Office.

Since my employees and I have been very satisfied with Salt's service so far regarding our mobile lines, I decided to trust them for a fixed line internet access as well. This was the best decision I have made recently because I benefit from exactly the same features I have been using, but at a lower price.

We wanted to change our internet provider when Salt launched their business service. Their all-in-one offer (broadband Internet + telephony) at an extremely attractive price immediately won us over! In addition, their online management tool is simple and efficient and their business support team went out of their way from the very first days to ensure that their services were working properly. Honestly, coming from another operator, I didn't expect such a good service! Thank you!

At Babycoeur, we pride ourselves in delivering excellent customer service and advice. So far, we have found the same quality of service and expertise with Salt Business for our mobile lines. A big well done to Pro Office. The Salt team has always been very committed and proactively follows our case. Thank you Salt team, thank you Assia!

EFOR GROUP, through its companies CVO-EUROPE and SOLADIS, has been a Salt customer for many years in the field of mobile telephony and, for some months now, has also been taking advantage of its fiber Internet offer. Our life science consulting and data processing activities require reliable, fast and accessible technology in the field, both in Switzerland and abroad. These criteria have been successfully met by Salt, both with its mobile network and its internet offering. We are also very satisfied with the fast and efficient support provided by the Salt teams and especially by our Account Manager, Philippe, who always finds the best solutions.

Our shop «Turi Shop» has been based in Brüttisellen (ZH) for 11 years. We receive many phone requests from customers, we have a checkout terminal which requires an internet connection and we also often work with large files online. That is why we rely on a stable and fast internet connection. After comparing various offers, we chose Salt because of its great value for money, its personal and helpful customer support and its state-of-the-art technology. Whether you have a question on mobile telephony, fixed telephony or internet, you are always just a call away from the right person and are not put on hold needlessly. That is the very definition of service. Fantastic!
