Understanding VoIP PBX and cloud voice services
Businesses need a phone system that operates reliably, integrates with CRM platforms, and helps manage sales effectively. On the market, there are two main solutions: Voice over IP-PBX and cloud voice services. Let’s explore the differences and determine which solution is more advantageous.
TL;DR
- VoIP PBX – a local IP-PBX hosted on your server or physical hardware. Ideal for companies that need full control over their phone system.
- Cloud Voice Services – a virtual PBX with no servers or complex setup required.
- Cloud systems scale faster, require no capital investment, and update automatically.
What is VoIP PBX and how it works
VoIP PBX (Voice over IP Private Branch Exchange) is a phone system operating over IP. It can be:
- Physical (hardware) – e.g., Yeastar S20 with SIP connectivity.
- Virtual on a server – e.g., 3CX on-premise.
Key features of VoIP PBX:
- Supports both internal and external communication via the Internet.
- Flexible call routing, IVR, and call queues.
- Works with SIP trunks and local carriers.
When to choose VoIP PBX:
- You have your own server and IT team.
- The business operates in areas with unstable internet connectivity.
- Strict security compliance is required (e.g., government organizations).
Cloud Voice Services – benefits and features
Cloud Voice Services are virtual PBX systems delivered as SaaS. Examples: CallGear, RingCentral, 8×8.
