Common Questions about Cloud Phone Systems
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.
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.

How are cloud phone systems different from on-prem 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.

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.
Can I migrate from my current hosting provider to Yeastar
.
Yes. In most cases, migrating to Yeastar cloud PBX is a straightforward process designed to minimize effort and disruption. You can migrate your existing PBX configuration, with core settings applied through guided steps rather than manual reconfiguration.
Yeastar also supports auto-provisioning for IP phones, making it easy to reconnect supported devices without on-site setup. SIP trunk settings, extensions, and call routing can be quickly re-applied or adjusted through the web-based management interface, allowing you to move services with confidence while keeping your existing numbering and integrations intact.
For more complex environments, the centralized management tools help ensure a smooth transition with minimal downtime.
