Cloud VoIP PBX for SMEs: complete guide 2025

Traditional phone systems have become a burden for many small and medium businesses: high maintenance costs, rigid lines and no remote work support. A cloud VoIP PBX solves all of these problems, often at a lower cost than legacy infrastructure.

What is a cloud VoIP PBX?

A cloud PBX is a business phone system managed entirely on remote servers. Instead of hardware in your office, all call routing logic, queues, IVR menus and extensions are managed over the internet via VoIP (Voice over IP).

Key advantages over traditional PBX

• Lower costs: no hardware to buy, predictable monthly fee, lower call rates
• Total flexibility: add or remove extensions in minutes, from anywhere
• Remote work ready: staff answer with the same business number from home or mobile
• Scalable: from 2 to 200 extensions without changing infrastructure
• Advanced features: IVR, priority queues, call recording, CRM integration

How much does a VoIP PBX cost?

Costs vary by user count and features. Typically:

• Monthly fee: €5-20 per extension, all-inclusive
• No hardware activation costs (a good internet connection is enough)
• Average saving: 30-60% vs traditional solutions

Virtual numbers and number portability

With VoIP you can have geographic numbers in Italy and across Europe — all managed from the same system. In most cases you can also port your existing number without changing it.
