American Securities | Banking and Financial Services | 190 | $85M | United States | RingCentral | RingCentral Cloud Phone System | PBX, VoiP and Phone Systems | 2021 | n/a |
In 2021 American Securities replaced its on premises Cisco VoIP with RingCentral Cloud Phone System. The RingCentral Cloud Phone System was deployed as the firmwide PBX for American Securities, classified under PBX, VoiP and Phone Systems, and was provisioned to support corporate voice, unified messaging, and desk and softphone endpoints across the New York headquarters and linked Shanghai office connectivity.
Configuration focused on cloud call control and standard PBX capabilities, including multi-tenant admin portals, auto attendant and call queue configuration, handset SIP provisioning, softphone clients, and voicemail to email workflows. RingCentral Cloud Phone System was configured to align with existing IT provisioning processes, user lifecycle controls, and telephony administration run by the IT Infrastructure and Operations manager.
The telephony deployment was integrated into the broader networking stack, explicitly leveraging the Velocloud SD-WAN implementation and the dual internet VPN tunnels that replaced the MPLS link to the Shanghai office. Voice traffic routing and internet circuit utilization were coordinated with the SD-WAN fabric, and the phone environment was operated alongside the firm’s IAAS and VMware vSphere infrastructure to centralize connectivity and resiliency controls.
Operational governance was owned by IT Infrastructure and Operations, which consolidated vendor and system monitoring into an in-house SolarWinds platform to centralize operational telemetry for voice and network systems. Rollout and ongoing maintenance were executed as part of standard IT infrastructure responsibilities, with telephony administration incorporated into existing change control and vendor management processes overseen by the infrastructure manager.

eBay UK | Retail | 320 | $18M | United Kingdom | RingCentral | RingCentral Cloud Phone System | PBX, VoiP and Phone Systems | 2015 | n/a |
In 2015 eBay UK deployed RingCentral Cloud Phone System to replace a Cisco solution, consolidating voice services under a cloud PBX architecture. The RingCentral Cloud Phone System implementation is described in the context of PBX, VoiP and Phone Systems and covered the London office of roughly 60 locally based staff with provisioning extended to about 1,000 users across the wider global estate.
Implementation work was project managed by the Systems Administrator and focused on cloud PBX configuration, VoIP extension and handset provisioning, and call routing policy setup consistent with PBX, VoiP and Phone Systems functional practices. The rollout included provisioning of new telephony hardware and coordination of inter-network connectivity, while operating alongside existing on-premises infrastructure such as the local vSphere cluster, EMC storage appliances, SCCM OS deployment tooling and the Office 365 email environment.
Operational governance centralized telephony administration into the existing IT support and asset management workflows, with the Systems Administrator acting as first point of contact for provisioning during acquisitions and for issuing hardware and user accounts. Support processes were integrated into everyday IT operations, including inventory tracking for devices and incorporation of telephony provisioning into established end user support and network readiness procedures.

Firebirds Wood Fired Grill | Leisure and Hospitality | 1000 | $250M | United States | RingCentral | RingCentral Cloud Phone System | PBX, VoiP and Phone Systems | 2017 | n/a |
In 2017, Firebirds Wood Fired Grill implemented the RingCentral Cloud Phone System. The deployment adopted a cloud first PBX architecture under the PBX, VoiP and Phone Systems category, centralizing voice services for the corporate office and a restaurant estate across the United States, covering more than 50 locations and approximately 1000 employees.
Implementation focused on cloud PBX provisioning, call routing and IVR configuration, hunt groups and call queue management, voicemail to email and unified messaging, and softphone and desk phone provisioning across sites. The RingCentral Cloud Phone System was configured through a centralized administrative portal for dial plan management, number assignment and presence management, with network optimization practices applied to preserve voice quality.
Operationally the phone system was supported by internal IT staff who handled RingCentral Phone Support in parallel with Cisco Meraki network infrastructure and ServiceNow ticketing for incident and change management. The implementation coexisted with point of sale systems including Micros and with the suite of third party services used by restaurant operations and delivery order flows, with help desk and onsite teams responsible for provisioning and troubleshooting during New Restaurant Openings.
Governance emphasized centralized administration and ServiceNow based change control, with field support workflows routing phone related incidents to dedicated IT support roles. Rollout sequencing relied on remote provisioning followed by local on site verification by IT Support Specialists and Help Desk Technicians to maintain continuity for restaurant and corporate business functions.

Giordanos Enterprises | Leisure and Hospitality | 800 | $200M | United States | RingCentral | RingCentral Cloud Phone System | PBX, VoiP and Phone Systems | 2019 | n/a |
In 2019 Giordanos Enterprises deployed the RingCentral Cloud Phone System to consolidate its communications under a cloud-first PBX, VoiP and Phone Systems platform. The RingCentral Cloud Phone System implementation used the RingCentral MVP suite and the RingCentral Admin Portal as the primary management interface for voice, video, and team messaging capabilities.
The implementation configured functional modules for centralized call routing, overflow reroute logic, phone number procurement, device ordering and activation, templated call instructions for new restaurant sites, and RingCentral Meetings for video collaboration. Administrators built a provisioning template library in the Admin Portal to accelerate site onboarding and to standardize call handling rules across locations.
Operational coverage targeted Giordanos restaurant locations across the United States and centralized operational ownership with the corporate IT team and restaurant leadership. Provisioning workflows that previously required contacting the telecom carrier were absorbed into the RingCentral Admin Portal, enabling remote setup from anywhere and reducing manual carrier coordination.
Governance changes focused on shifting routine provisioning and policy control to the RingCentral Admin Portal, empowering IT to set up new restaurants in minutes and maintain consistent call routing templates. The change reduced device and phone number provisioning friction and streamlined communications governance between IT and restaurant operators.
Explicit outcomes reported by company leadership include faster provisioning, reduced time cost and aggravation for the IT team, more reliable customer call handling during peak carryout periods, and positive staff feedback on video meeting and calling quality. The platform also enabled senior leadership to spend less time managing communications hardware and vendors and more time on business initiatives.

Metropolitan Thames Valley | Non Profit | 1938 | $498M | United Kingdom | RingCentral | RingCentral Cloud Phone System | PBX, VoiP and Phone Systems | 2021 | n/a |
In 2021 Metropolitan Thames Valley implemented RingCentral Cloud Phone System as part of a coordinated communications and infrastructure program. The RingCentral Cloud Phone System is classified under PBX, VoiP and Phone Systems and was deployed alongside O365 and Microsoft Teams workstreams to modernize enterprise telephony.
The deployment centered on RingCentral SIP telephony with cloud call control, user provisioning, and call routing configured to support large scale user migration. Implementation activities included champion group creation and end user training to drive adoption, plus a formal service support handover to operations at the conclusion of the program.
Integrations were explicit with O365 and MS Teams, and the project included decommissioning of Microsoft Skype for Business as the legacy telephony signaling platform. The wider technical program also encompassed upgrades and moves of Serengeti and Oracle servers to Windows servers in corporate data centers, a data center migration and disaster recovery cutover including link and equipment moves, and a LAN and WAN refresh using CISCO ACI.
Program governance followed a strict project delivery model, running from Jan 2021 to Aug 2021 with responsibilities to manage scope, schedule, budget, and risk. The project team escalated risks and issues to project sponsors, liaised with suppliers for technical workstreams, and closed the telephony transition with service support handover and Skype for Business decommissioning.
