From healthcare to high-tech, the cloud is transforming the way organizations communicate and collaborate—internally as well as with customers and partners. By accessing one centralized communications system in the cloud, businesses and government agencies can leverage the benefits of voice over IP (VoIP) telephony combined with productivity features such as business SMS, online meetings, team messaging, and mobility.

Organizations looking to move communications and contact center functions to the cloud naturally have concerns over availability and security. Nothing is more vital to an organization than these core communication functions. Consequently, it pays to choose a cloud communications provider with not only numerous satisfied customers but also the advanced network architecture required to ensure security and high availability.

Industry-leading Cloud Communications

Recognized as a leader in the Gartner Magic Quadrant for Unified Communications as a Service (UCaaS), Worldwide for the 5th consecutive year, RingCentral has a proven track record of supplying cloud business communications services to hundreds of thousands of customers worldwide. More than a decade in the making, the RingCentral platform combines voice, business SMS, audio and HD video conferencing, fax, web meetings, team messaging, and contact center capabilities, as well as integrations with leading cloud apps such as Salesforce®, Microsoft Office 365™, and G Suite.

To provide customers with carrier-grade reliability, RingCentral created a robust global network backbone—and built relationships with leading carriers—to ensure we control not only the virtual PBX infrastructure in the data center but also the quality and cost of the network connections that our service uses.

This network comprises a robust redundant service delivery architecture that is built from the ground up to ensure the highest quality of service, reliability, scalability, and security. It currently handles over 1 billion minutes of voice traffic per year, and our facilities have more than twice the capacity currently used by our customers.

In addition to strong security designed to protect customers' communications and data, RingCentral carrier-grade reliability and high availability includes security measures that help to ensure customers' service is not disrupted by any threat.

Hardened, Geographically Dispersed Data Centers

Data centers located on both US coasts house the core RingCentral technology infrastructure and connect with our international data centers to provide our global network. Designed to provide industry-leading availability and security, these facilities are paired in an active/ active architecture to support failover and switchover, as well as the ability to sustain service in a single data center when needed (i.e., one per pair, not one globally). The infrastructure is co-located with all the major US telecommunications carriers. This redundant architecture supports a 99.999% SLA and provides virtually unlimited capacity for growth. Our service operations are audited against the SSAE-16 criteria for security and availability, and audit reports are available to customers.

Each RingCentral data center is supported by redundant power and protected by an array of security measures to control, monitor, and record access to the facility. All equipment areas are monitored and recorded using CCTV, and all access points are controlled. Every data center is staffed with security officers on duty 24 hours a day. Visitors are screened upon entry to verify identity, and access history is recorded for audit by customers.

Anti-DDoS Measures

There is no definitive way to prevent VoIP DDoS attacks—whether service is on premise or hosted in the cloud. However, the RingCentral architecture includes a number of anti-DDoS measures, including border session management that is resilient to many forms of attack and packet malformation.

RingCentral security measures designed to prevent DDoS include:
  • Session border controllers with anti-DDoS measures
  • Protecting against spoofed messages by validating the value of "Call-ID," "Tag," and "branch" while processing control NOTIFY messages
  • A caller identification system that authenticates calling numbers via certificates
  • Detecting malicious service usage patterns
  • Technology layers that include:
» Intrusion detection systems
» System logs
» Fraud analytics

  • Internal operation processes that provide:
» Service-level monitoring
» System hardening
» Change Management
» Regular vulnerability scans

RingCentral is continually upgrading these protections. Future plans include implementing a secondary DNS and a traffic scrubbing/DDoS mitigation service.
Intrusion Protection

In addition, an advanced suite of intrusion prevention technologies—including advanced border session management—protects against malformed packets and fuzzing techniques, which can be used to confuse or overwhelm border controllers resulting in service disruption, system restart interruption, and endpoint resets. RingCentral deploys best-of-breed network protections that are optimized for VoIP data. These protections, together with RingCentral's Operations team continuously monitoring systems for anomalies help to prevent service disruption, fraud, and service hijacking.

RingCentral's NAT traversal functionality overcomes the typical set of firewall traversal problems in VoIP systems with network address translation (NAT) support for static IP configuration and "Keep-Alive" SIP signaling. This maintains user addressability without requiring our customers to open broad ranges of VoIP ports on their networks.


The RingCentral service architecture supports hundreds of thousands of users, and is designed to handle 2x capacity. The modular pod design offers remarkable flexibility and enables us to seamlessly integrate additional pods as our subscriber base continues to grow.

Unlimited numbers of new user groups can be added at any time, without the need to take the entire system offline to rebuild databases and add new servers. There are thousands of network application triggers that alert us when a reallocation of resources is required, and the entire system is constantly monitored for any bottlenecks or other blockages.

In addition, the pod architecture incorporates a virtual chassis deploying a direct-path algorithm that enables multiple individual physical switches to act as one via a high-speed link—they can couple or uncouple depending on system demands. The result is optimal traffic flow, superior flexibility, and instantaneous scalability.

Regardless of system load, the RingCentral platform is robust enough to handle unforeseen spikes in activity. Additionally, that capacity is always fully available as we separately operate a full-scale laboratory environment offline to thoroughly test any network changes before we roll them out, meaning our expansion activities never affect our customers' phone service.
