Ascensos Limited | Professional Services | 2587 | $81M | United Kingdom | Calabrio | Calabrio ONE | Employee Engagement | 2023 | n/a |
In 2023, Ascensos Limited deployed Calabrio ONE for Employee Engagement to schedule and manage its agent workforce across seven contact centre locations in the UK, Romania, Turkey, and South Africa. The deployment covers scheduling for approximately 2,500 agents who handle roughly 170,000 contacts per week, with a channel mix that is predominantly voice 59 percent, followed by email 20 percent, live chat 10 percent, social media 10 percent, and WhatsApp 1 percent. Calabrio ONE serves as the central Employee Engagement platform for resource planning and workforce performance at Ascensos.
The configuration emphasizes Calabrio ONE automated workforce management capabilities, including scheduling, forecasting, workforce optimization, agent engagement features, business intelligence, and a self service agent application. Agents use the self service app to manage about 4,700 breaks and 1,100 holiday requests weekly, while team managers schedule roughly 1,700 offline activities such as meetings, one to one sessions, and return to work coaching. The solution provides a 12 month forward view of schedules, self scheduling options, shift swaps, and automated notifications for overtime opportunities.
Deployment leverages Calabrio ONE true cloud architecture to orchestrate scheduling and forecasting across multiple sites and client accounts, enabling centralized workforce performance administration while supporting local team manager workflows. Operational coverage explicitly includes resource planning, team management, and front line agents across Ascensos contact centres, with use cases tied to meeting client service level agreements. The implementation uses Calabrio ONE analytics and WFM modules to align agent availability with demand patterns.
Reported outcomes from the rollout include 375 hours saved per week in resource planning effort, cited as equivalent to 13 full time employees, and an estimate that three minutes are removed from each action, equating to 22,500 minutes saved weekly. Ascensos also reports increased staff engagement driven by schedule flexibility and transparent access to overtime and shift options through Calabrio ONE. Governance shifted toward agent self service scheduling, manager curated offline activities, and centralized WFM oversight.

Mersey Care NHS Foundation Trust | Healthcare | 11498 | $965M | United Kingdom | Calabrio | Calabrio ONE | Employee Engagement | 2025 | n/a |
In 2025 Mersey Care NHS Foundation Trust implemented Calabrio ONE as an Employee Engagement application to underpin its 24/7 urgent mental health Crisis Helpline. The deployment was delivered in partnership with NHS Informatics Merseyside and ITGL and was scoped to support clinicians across more than 170 clinical services sites serving Cheshire and Merseyside, with commissioned coverage extending into North Wales and the Midlands.
Calabrio ONE was configured to provide core capabilities for contact analytics, automated transcription, contact summarization, text to speech, real-time dashboards, call recording, and configurable call routing based on urgency. Calabrio Analytics is used to generate 150 word summaries within ten minutes, to flag repeat contacts, and to produce live and historical reports for queue management, abandoned call analysis, and agent availability, enabling clinicians to reduce after call administration.
The solution was integrated with Cisco Webex Contact Center and the Webex platform to deliver multichannel voice handling, real-time data flows, and board level proof of concept verification based on analysis of over 1,000 calls. The architecture supports third party integrations and was designed with flexibility to enable generative AI oriented workflows, while providing clinicians with non technical user interfaces such as real time demand visuals and live reporting for acuity management.
Operational governance emphasized clinician usability and clinical prioritisation, with routing rules to ensure critical calls are escalated to the right clinicians immediately and dashboards to prompt clinical escalations and resource mobilisation. Analytics and recorded contacts have been embedded into supervision and team based learning processes to identify training needs and to audit repeat contact patterns, and the platform supports wellbeing monitoring by identifying clinicians exposed to high volumes or abusive contacts.
Outcomes reported by the Trust include identification that 21% of contacts handled by clinicians are clinical, and discovery that 15.3% of contacts are repeat callers. Calabrio ONE reduced time spent on after call notes through automated transcription and summarization, increased workforce capacity across skill sets, and supported the helpline as it scaled from an average of 2,000 to 9,000 calls handled per month with half a million more registered users since 2020.

In 2021 Vanderbilt University Medical Center implemented Calabrio ONE to support Employee Engagement for its 300 seat call center, establishing an institutional workforce management capability tied to call center operations. The deployment centered on Calabrio ONE Workforce functionality and was led by a newly created Workforce Management team responsible for operationalizing forecasting and staffing strategy across leadership and agent populations.
Configuration work concentrated on forecast models, staffing and scheduling, timekeeping and vacation rules, and real time monitoring and reporting workflows. Calabrio ONE Workforce was configured to deliver daily schedules, intraday adherence monitoring, and agent behavior reporting, and training was delivered to both leadership and agents on the Calabrio ONE application and associated workforce procedures.
Operational coverage included the Vanderbilt University Medical Center call center in Nashville TN, with the workforce team providing daily leadership reporting in morning meetings and ongoing schedule and occupancy oversight for approximately 300 seats. The implementation impacted call center workforce operations, contact center leadership, and agent timekeeping and staffing processes.
Governance and process changes included creation of written policies and procedures for timekeeping and vacation, the establishment of daily operational review rituals, and role based training for workforce managers and supervisors. The program emphasized using Calabrio ONE Workforce data to inform forecasting and staffing decisions with the objective to maximize utilization and provide optimum service levels and occupancy for the call center.
