What is Hosted VoIP?

Hosted VoIP: Hosted VoIP is a phone service where all the hardware, software, and infrastructure is maintained by a third-party provider (like VestaCall) in the cloud — rather than at your business location. You pay a monthly subscription and access the phone system via apps and IP phones.

How It Works

The VoIP provider hosts servers, manages software updates, ensures uptime, and handles all telephony infrastructure. Your business connects to this hosted system via the internet. Employees use web apps, mobile apps, or IP desk phones. The IT team manages users and settings through a web-based admin portal — no server room needed.

Business Use Cases

Small businesses with no IT staff use hosted VoIP to get enterprise phone features without managing hardware. Growing companies use hosted VoIP to add users instantly without hardware procurement. Companies with multiple offices use hosted VoIP to unify communications across locations with one provider and one bill.
