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.
