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.

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. With Virtual PBX you are spared the investment in expensive hardware of your own and benefit from attractive 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).
