What is a Cloud PBX?

Cloud PBX (Cloud-based Private Branch Exchange) is a phone system that operates in the cloud rather than using traditional on-premises hardware.

It leverages VoIP (Voice over Internet Protocol) technology to handle incoming and outgoing calls over the Internet. Instead of physical phone lines, users connect to the Cloud PBX using IP phones, softphones (software-based phones), or mobile devices with dedicated applications.

Cloud phone systems are hosted by service providers, eliminating costly infrastructure since they are billed on a flexible subscription plan.

Common Questions about Cloud Phone Systems

How does Cloud PBX works?

.

A cloud-based PBX operates entirely over the Internet and is managed remotely. Its deployment and setup are effortless, relieving businesses from IT burdens.

Typically, the cloud phone service is obtained via subscription with a service provider. With this setup, calls can be made and received using IP phones, mobile devices, or other compatible devices. Voice traffic is transmitted over an Internet connection, which connects to data
centers located within the cloud.

To see an intuitive diagram of how it works.↗

How are cloud phone systems different from on-premises ones?

.

  • Infrastructure: On-premises systems require physical hardware installed and maintained on-site, while cloud phone systems operate in the cloud without the need for on-site equipment.
  • Maintenance and Updates: With on-premises systems, businesses are responsible for maintaining and updating themselves. Hosted phone systems handle these tasks at the service provider’s end.
  • Scalability and Flexibility: Cloud phone systems allow businesses to add or remove users and features with just a few clicks. On-premises systems may require purchasing and configuring additional hardware.
  • Cost Structure: On-premises systems involve upfront capital expenditures and ongoing maintenance costs. Cloud PBX operates on a subscription-based model with predictable monthly fees.
  • Reliability and Redundancy: Virtual PBX often have built-in redundancy and multiple data centers, ensuring high availability.
  • Remote Accessibility: Cloud phone systems allow users to make and receive calls from anywhere with an internet connection.

Why choose Yeastar Cloud PBX?

.

  • More than a PBX: Yeastar Cloud PBX is an all-in-one solution for modern business. Empower your team with inbuilt call center solution, Linkus,
    omnichannel messaging, and more advanced VoIP features in one package.

    more savings.
  • Open Ecosystem: Yeastar phone system is integrated with Microsoft Teams, popular CRMs, and more 3rd-party platforms to drive teamwork productivity and customer experience.
    Moreover, we are setting foot on the contact center market, introducing WhatsApp and SMS integration to the P-Series Phone System for an omnichannel messaging experience.

Can I connect my existing PBX to the cloud?

.

Yes. Yeastar allows you to connect your existing on-premises PBX to the cloud using SIP trunking. Instead of traditional phone lines or primary rate interfaces (PRI), your PBX need to connect to the public switched telephone network (PSTN) through the internet.

SIP trunking offers a hybrid solution that enables the integration of legacy systems with cloud-based services. That means you have the option to gradually migrate to the cloud PBX, ensuring uninterrupted communication for your business.
