Why is Business Voice Virtual PBX from UPC Business so cheap, and what is the difference compared to a conventional fixed network connection?

Virtual PBX from UPC Business allows you to run your telephone via your Internet connection. So you can circumvent the traditional domestic connection. The Virtual PBX connection is based on a Business Internet Fiber Power connection, which is why it can be offered so cheaply.

Does Virtual PBX by UPC Business work with a conventional telephone device?

Conventional telephone devices (analogue or ISDN) can no longer be used. You require IP-enabled telephone devices (SIP telephones) for a Virtual PBX connection. You will be given the option of choosing from various models during the order process. Our installation partner will configure all the devices during the on-site installation.

Do I need a PC to use Virtual PBX by UPC Business?

No, that is not automatically necessary unless you use a softphone that is installed on your PC. Virtual PBX allows you to dial any telephone in the world with your IP phone, without needing a PC. You can also be called from any connection in the world at any time.

How can I make calls with Virtual PBX by UPC Business?

You need a Business Internet Fiber Power connection with a bandwidth of 200/20 Mbit/s, 500/50 Mbit/s or 1000/1000 Mbit/s.

How can I use Virtual PBX by UPC Business for my company?

Virtual PBX from UPC Business allows you to replace your existing physical telephone system with what is known as a cloud solution. This means you are using a virtual and outsourced modern telephone solution. As long as you have an efficient Internet connection, this provides you with global access to the telephone system wherever you are. You can also use the telephone system when you are on the move or abroad with your mobile phone (via app) or from a PC/laptop (via web portal) – just as if you were physically present in your office. Virtual PBX saves on investment in expensive hardware and has the advantage of lower call costs. Within your organisation all participants can call each other for free, even between company locations.

Is the call quality as good as with traditional telephony?

Yes, Virtual PBX by UPC Business allows you to make calls with the call quality you would usually expect. To ensure this quality, voice transfer is prioritised over the other data packages (quality of service – QOS).


Prices displayed do not include VAT.

The prerequisite for an Internet, telephone or Digital TV connection is a return path-compatible cable connection from UPC or one of our partner networks. In leasing contracts, the costs of this connection (generally CHF 36.90 per month) are mostly contained in the additional costs.

The Business Flatrate is designed for standard connection use by business customers. If usage deviates considerably from standard use or if there are reasonable indications that the connection is being used for special purposes (e.g. machine-machine, direct dialling or continuous connections, video telephony, call centre services, permanent monitoring services or extensive analogue data transmission), UPC reserves the right to suspend the service at any time, to restrict it or to take another suitable measure.
Calls to Swiss and foreign service and business numbers incurring costs (e.g. 0869x, 0878x, 18xy, 084x, 090x) and to Internet dial-up numbers and access numbers for prepaid and calling card offers are excluded from the Business Flatrate. Usage fees charged by service providers will also be billed to the customer.
