FAQs about business phone systems

A cloud private branch exchange (PBX) system enables business phone system functionality without owning or maintaining all necessary equipment. When you choose a cloud PBX system, housing the PBX system becomes the responsibility of your service provider. 
Cloud PBX providers typically charge a monthly cost. This covers off-site housing of infrastructure, managing the technology to maintain the phone system, and feature updates.
This means that by moving your business communications to the cloud, you get all the standard PBX features—fax, voicemail, paging, call routing, call recording, business SMS, and more—at a lower, more predictable cost. Plus, with RingCentral, you also get an all-in-one solution that covers team collaboration, messaging, video chat, analytics, automatic updates, and administration services.
RingCentral’s cloud PBX solutions also boast built-in redundancy that ensures no loss of functionality,  enterprise-grade security for businesses of all sizes, and infrastructure hosted in top-tier data centers.
Cloud PBX makes it possible to make and receive calls using any device. Team members can use their laptops, desktops, or mobile devices for real-time communication. A strong internet connection is all you need, and you are good to go!
The timing of a migration from an on-premises PBX to a cloud phone system should be a strategic decision. Many organizations consider factors such as asset depreciation, migration logistics, and ongoing maintenance and upgrade costs.
However, aligning strategically with the business's goals usually takes precedence. As companies integrate AI into workflows, transition from capital to operating expenditures, expand into new countries and regions, or embrace mobile workstyles, the timeline to migrate from an on-premises PBX to a business cloud phone may accelerate.
Large enterprises with many users, locations, and lines may face complexity when migrating from an on-premises PBX to the cloud. Those organizations may have disparate systems that require consistent connectivity or operate in industries where on-premises hardware is necessary to comply with regulations. Others may need a phased, strategic approach, moving users, locations, or lines at different times to ensure business continuity and to manage the capacity of their IT teams.
These well-laid plans can span years as these large enterprises shift to a cloud-based solution. Cloud business phone providers that enable hybrid deployments, allowing some users to stay on-premises while others reside in the cloud, provide the flexibility that most enterprises need to successfully execute a cloud migration.
Businesses have different requirements when it comes to streamlining workflows, improving productivity, and enhancing communications. 
RingCentral can help by allowing you to integrate phone, SMS, and faxing capabilities into your favorite business apps like Google, Microsoft, and Salesforce. We also offer open APIs, SDKs, and widgets that you can utilize to create integrated apps that work for your business’ unique needs. Check out the RingCentral App Gallery for more information about what you can do with our cloud communications platform.
There is an abundance of cloud options available for consideration, each requiring careful evaluation to align with your business and financial requirements. 
When evaluating cloud business phone systems, be sure to consider tools like:
  1. Seamless integration capabilities with key business tools such as Salesforce, Hubspot, Zendesk, and others.
  2. Robust administration and analytics features enabling remote troubleshooting and usage management.
  3. Comprehensive user experiences across mobile, desktop, and deskphone environments catering to both basic and advanced users.
  4. Expanded functionality encompassing telephony, SMS/MMS, and internet fax services.
  5. A proven track record of reliability and security.
  6. Streamlined migration pathways to the cloud, accommodating phased transitions from on-premises setups, particularly relevant for larger deployments.
