What is a hosted PBX phone system?

A hosted PBX is a business phone system that lives in the cloud instead of in a closet. Vast Networks owns and operates the call-processing platform, delivers it over our private fiber network, and manages every update, patch, and feature for you — so your team gets enterprise calling without buying, housing, or maintaining a single piece of phone hardware. You add a seat, plug in a phone or open the softphone app, and you are live.

Hosted PBX vs. on-premises PBX

A traditional on-prem PBX means capital outlay for hardware, a server room, ongoing maintenance contracts, and a forklift upgrade every few years. Hosted PBX flips that to a predictable per-seat subscription with no hardware to own. Capacity scales instantly, new features arrive automatically, and there is nothing on-site to fail — Vast Networks runs the platform and backs it with a carrier-grade voice SLA.

Why deliver voice over private fiber?

Voice quality is only as good as the network underneath it. Many cloud phone providers send your calls across the public internet, where jitter, packet loss, and congestion cause dropped words and choppy audio. We carry hosted PBX traffic over our own private fiber backbone with sub-5ms voice latency, so every call sounds clear and connects reliably — even during peak hours.

Enterprise features, included

Auto attendants, IVR menus, ring groups, call queues, hot desking, voicemail-to-email with transcription, on-demand call recording, conference rooms, and CRM integrations all come standard. Your desk phone, desktop app, and mobile softphone share a single extension, so staff answer and place calls from the office, home, or the road with one identity.

Is hosted PBX right for your business?

Hosted PBX is the simplest path to modern business calling for growing and distributed teams, multi-site offices that want one unified system, support and call-center operations, and anyone retiring aging on-prem hardware. If you want enterprise phone features, zero maintenance, and the freedom to work from anywhere, hosted PBX is built for you — starting at $15 per seat with 24/7 US-based support.

Hosted PBX FAQs

Common questions about hosted PBX, pricing, number porting, and remote work.

What is a hosted PBX?

A hosted PBX is a cloud-based business phone system. Vast Networks owns and operates the call-processing platform and delivers it over our private fiber network, so you get enterprise calling features without buying or maintaining any on-site PBX hardware. You simply add seats and connect desk phones or softphone apps.

How is hosted PBX different from an on-premises phone system?

On-prem systems require you to purchase, house, and maintain hardware and upgrade it every few years. Hosted PBX moves all of that to the cloud for a predictable per-seat subscription, scales instantly, updates automatically, and has nothing on-site to fail — all backed by a carrier-grade voice SLA and 24/7 support.

How much does hosted PBX cost?

Hosted PBX starts at $15 per seat per month and includes the full enterprise feature set — auto attendants, IVR, call queues, voicemail-to-email, call recording, softphone apps, a DID with E911, and number porting. Final pricing depends on seat count and any add-ons, which we confirm in your quote.

Can I keep my existing phone numbers?

Yes. We handle no-hassle number porting for your existing local and toll-free numbers and coordinate the cutover so there is no downtime. Your customers keep dialing the same numbers they always have.

Can my team work remotely with hosted PBX?

Absolutely. Every seat includes desktop and mobile softphone apps that share the same extension as the desk phone, so staff can make and receive business calls from the office, home, or the road — ideal for remote and hybrid workforces.

Do I need special equipment or technical staff?

No. Because the platform is fully managed in the cloud, there is no PBX hardware to install or maintain. You just need IP phones or the softphone app and an internet connection — and our 24/7 US-based team handles configuration, updates, and support for you.
