Unifying communications with Teams for a global manufacturer with 450+ sites

A leading global food manufacturer needed to modernise communications across its international offices and factories. With operations in multiple countries, the business required a solution that could support both scale and local compliance.

The company was managing five separate systems — legacy PBX, fax, contact centre, SMS and video conferencing — across multiple vendors. This created complexity, slowed deployment and increased the burden on internal teams. They wanted one cloud-based solution built around Microsoft Teams, delivered by a single global partner.

SCB Global consolidated these services into one Microsoft Teams-based communications platform hosted in Azure. Using its OPTO solutions, SCB Global unified telephony, contact centre and customer communications, while also supporting local number requirements and compliance in countries including China and Indonesia. A dedicated project management team helped deliver the rollout smoothly across global sites.

The new solution is on track to save the manufacturer tens of millions of dollars over the coming years. It also reduced vendors from eight to one and cut deployment times from 6–12 months to just two months maximum. The result is a simpler, more efficient and more scalable communications environment.

Whether you have a contact centre with 1,000 agents or you require some departments to have extra functionalities, we deliver a fully customisable solution within Teams

Simple setup and customisation

Get up and running fast with a setup that’s designed to be simple, not stressful. Customise queues, routing and agent settings to fit how your team works, without a big IT project.

Work distribution

Automatically route work to the right person, at the right time, based on skills, availability or priority. This keeps queues moving, reduces missed contacts, and helps every agent stay productive.

CRM integration

Connect OPTO4Contact to your CRM so agents have the context they need before they even say hello. Log interactions and keep customer records up to date, so nothing gets lost between systems.

Flexible channel interaction

Support customers across the channels they actually use, and switch between them smoothly when needed. It’s one joined-up experience for the customer, rather than separate conversations in separate tools.

Compliant call recording

Record calls securely to support quality, training and compliance requirements. Access recordings when you need them, with controls that help you stay aligned with internal policies and regulations.

Agent performance and analytics

Track performance with clear reporting on activity, outcomes and service levels. Use insights to spot bottlenecks, coach agents effectively, and improve the customer experience over time.

Pet supplies plus case study text here

Pet Supplies Plus is a privately held US pet supplies retailer with 460+ franchise stores. With 30 years in the industry and a strong focus on customer experience, they needed communications that could keep pace with a modern, distributed workforce.

A mix of hybrid working, an ageing on-site PBX estate, and the hassle of managing multiple PBXs across hundreds of locations pushed Pet Supplies Plus to look for a cloud-first alternative.

They wanted:

  • A “single pane of glass” approach to reduce complexity and improve control
  • One unified communications platform for stores and HQ
  • Microsoft Teams as the main collaboration hub (building on existing Office 365 licensing)
  • Key calling features inside Teams, including direct routing, IVR, call queuing and call routing

SCB Global deployed OPTO4Teams, a native Microsoft Teams integrated voice solution (in market since 2019, pre-pandemic) with enhancements beyond basic direct routing.

Delivery highlights:

  • Rolled out store-by-store across all 460 locations, keeping operations running as normal
  • Implemented by SCB Global’s project management team
  • Ran in multiple redundant Azure locations to prioritise voice quality and resilience
  • Seamlessly ported existing numbers from current carriers into Teams, using SCB Global’s telco experience to minimise downtime
  • Ensured business continuity with agreed cutover times and E911 support

Pet Supplies Plus now has a high-availability, modern communications setup fully integrated with Office 365 and Microsoft Teams.

Key outcomes:

Removed legacy PBX support, maintenance and on-site hardware

  • Improved collaboration between store teams and HQ inside Teams
  • Enabled smoother communication with customers and suppliers
  • Reduced costs by bringing communications into one system
