What is cloud PBX?
A cloud-based Private Branch Exchange (cloud PBX) is a phone system that delivers advanced calling features and unified communications using Voice over Internet Protocol (VoIP) technology. Cloud PBX systems are hosted by service providers, eliminating costly on-premises hardware since they are billed on a monthly or annual subscription.
Compared to traditional landlines, businesses get greater flexibility, scalability, and reliability with a cloud PBX service. It provides professional features like auto-attendants, call routing, integrations, and video conferencing.
With a cloud PBX solution, you only need an internet connection to make and receive calls, send messages, and work from anywhere.

Cloud PBX FAQs
How does a cloud PBX work?
A cloud PBX system is hosted and managed by a service provider rather than on-premises hardware. The provider delivers virtual PBX capabilities virtually over the internet using VoIP technology instead of analog phone lines.
Virtual PBXs allow for advanced functionality like auto-attendants, interactive voice menus, call routing, voicemail transcription, and more. Users simply need IP phones or softphones to make and receive calls through the cloud PBX.
Is it hard to set up a cloud PBX phone system?
No, a cloud PBX system is easier to set up than an on-premises PBX. There is no complex hardware to install. Just connect your IP phones and computers to the internet. The service provider completely handles the PBX configuration and functionality in the cloud.
Management uses an online portal to make changes, add extensions, manage call routing, etc. With just an internet connection, your team can benefit from virtual PBX features right away.
Can I connect my existing PBX to the cloud?
Yes, you can connect your current on-premises PBX to a cloud-based provider using SIP trunking. SIP trunks connect your existing PBX to the public switched telephone network (PSTN) via the internet instead of traditional phone lines or primary rate interfaces (PRI).
Blended SIP trunking with a cloud phone system deliver cost savings, geographic flexibility, and business continuity. It also lets small businesses gain enterprise functionality like HD video meetings, unified messaging, mobility features, and more while using your existing PBX investment. SIP trunking provides a hybrid approach to connect legacy systems to the cloud.
When migrating from an on-site traditional PBX, you can roll out your cloud PBX in phases to ensure your business communications are uninterrupted.
Is a cloud PBX service cost-effective?
Absolutely, a cloud-hosted PBX system eliminates expensive upfront hardware costs, ongoing maintenance fees, and real estate. The monthly subscription is typically much lower than purchasing an on-prem PBX.
You only pay for what you use instead of excess capacity. Cloud PBX systems seamlessly scale to match your changing business needs, keeping costs aligned to usage.
Productivity-enhancing features like auto-attendants, IVRs, call analytics, and integrations are built-in rather than add-ons. A cloud PBX delivers enterprise-level functionality for a small business price.
How much does a virtual PBX cost?
Expect to pay about $25-35 per user monthly for cloud-hosted PBX service. There aren’t typically upfront costs like servers, real estate, or personnel to configure it.
Nextiva’s cloud-based virtual PBX price starts at $18.95 per user monthly. Chat with one of our VoIP experts to get a customized quote based on your business needs.
The question isn’t how much a virtual PBX costs but rather how much your current PBX costs you. Want to see how much you can save? Get a no-obligation PBX price quote today!
Can enterprises use a cloud-based PBX?
Yes, enterprises are increasingly switching their legacy on-premises PBX in favor of cloud-based PBX systems for their performance, reliability, and flexibility. Leading service providers offer robust SLAs of 99.999% uptime and redundancy across multiple data centers.
Cloud PBX solutions can scale to support many extensions, sites, and users. It provides mobility, unified communications, call encryption, and virtual phone number capabilities suitable for large enterprises with distributed teams. The cost savings and management upside of using a cloud PBX service makes it viable for larger organizations.
