Managing Manufacturing Phone Systems with Microsoft Teams: Advice from a Microsoft MVP  

Over the years, I’ve worked with manufacturing businesses across multiple industries, supporting Microsoft Teams deployments, hybrid telephony environments, and large-scale communication strategies. 

And one thing is consistent: manufacturing communication is rarely simple, and almost never centralised. 

Most organisations don’t start with a clean architecture. Instead, what they have is a mix of legacy systems, newer platforms like Microsoft Teams, multiple carriers, and often additional tools such as contact centre platforms or Webex in certain regions. 

Individually, these systems work. But together, they create complexity. 

Deloitte’s 2025 Smart Manufacturing research highlights that more than 80% of manufacturers are investing in digital connectivity. That shift is driving demand for communication systems that are integrated, scalable, and operationally aligned. 

The challenge isn’t adopting new technology. It’s making everything you already have work together. 

Common Communication Challenges in Manufacturing Organisations

Across manufacturing organisations, I consistently see the same patterns emerge. These aren’t theoretical challenges, they are real operational issues that impact IT, operations, and leadership. 

Manufacturing environments evolve over time, and communication systems often lag behind that evolution. 

1. Manufacturing Multi-Site Complexity Without Central Control

Manufacturing organisations typically operate across multiple sites, often globally. Each site may have different carriers, different routing logic, and different systems in place. 

For IT teams, this creates fragmented management and duplicated effort. 

For operations, it creates inconsistency in how communication works across sites. 

I’ve seen scenarios where identical processes behave differently depending on location simply because telephony isn’t aligned. 

Recently, I worked with a global pharmaceutical company reviewing their telephony setup. It was obvious this was their first attempt at globalising telephony – a complex task. As we developed the Microsoft Teams environment, we noticed repetitive requirements across regions, such as Dial Plans and Voice Routing Policies, not to mention local regulations. Addressing these needs region by region was essential, especially considering rules like E911 in the USA. Creating a design diagram is only the beginning. 

2. Microsoft Teams in Manufacturing Is Only Part of the Solution

Across the manufacturing sector, Microsoft Teams is increasingly being adopted to connect office-based and frontline workers, extending communication into operational environments, as highlighted in UC Today’s coverage of Microsoft Teams for manufacturing. 

However, in practice, Teams rarely replaces existing systems entirely. 

Instead, it sits alongside legacy telephony, contact centre platforms, and other tools. 

From my experience, the challenge isn’t the presence of multiple systems. It’s the lack of orchestration between them. 

For instance, I collaborated with a customer who was among the first to successfully implement Microsoft Teams throughout their organisation. At that time, certain applications, such as contact centers, PA systems, tannoy systems in manufacturing areas, and door access controls, were not yet supported. As Microsoft Teams developed further, features like the SIP Gateway and partner solutions from Algo Communications addressed some of these needs. However, Microsoft Teams cannot serve as an all-in-one platform; integration with other services will always be necessary. Although this integration isn’t completely seamless, it shouldn’t impact the overall user experience. 

3. Manufacturing Routing at Enterprise Scale

Routing is one of the biggest challenges at scale. Manufacturing organisations need routing that adapts to shifts, roles, and operational workflows. But in many environments, routing is fragmented across systems and managed manually. 

With thousands of users, even small changes become complex and time-consuming. 

This creates delays, errors, and inefficiencies across the organisation. 

4. Lack of Visibility Across Manufacturing Systems

One of the most common issues I see is a lack of visibility. 

In a large-scale environment supporting thousands of users, I’ve seen situations where troubleshooting a single call required checking three or four different systems—each providing only part of the picture.  

When something goes wrong, there’s no single place to diagnose the issue. IT teams must check multiple systems, which slows down troubleshooting. 

Industry Today highlights how communication gaps between frontline workers and central teams impact efficiency across manufacturing environments. 

Without visibility, organisations cannot optimise or scale effectively. 

The Business Impact of Fragmented Manufacturing Communication Systems

In practice, these challenges don’t show up as “technical issues”, they show up as operational friction across the business. 

From what I’ve seen working with manufacturing organisations, the impact is felt differently depending on the stakeholder. 

Operational Inefficiency and Delays 

When communication isn’t aligned to how the business operates, delays become inevitable. 

Calls don’t reach the right teams quickly enough, particularly across: 

• Shift changes  

• Site handovers  

• Escalation scenarios  

In one multi-site manufacturing organisation, delays in routing between regional plants meant that issues which should have been resolved in minutes were taking significantly longer, simply because calls weren’t being directed to the right team first time. 

At scale, those delays compound. 

Increased IT Complexity and Overhead 

For IT teams, fragmented environments create a constant operational burden. 

Instead of focusing on optimisation or innovation, teams are: 

• Managing multiple platforms independently  

• Repeating changes across systems  

• Troubleshooting across disconnected environments  

In one environment, a simple routing change required coordination across three different platforms, each owned by different teams. 

That’s not sustainable at enterprise scale. 

Inconsistent User Experience Across the Business 

From a user perspective, communication becomes unpredictable. 

• Office users rely on Teams  

• Operational users rely on legacy systems  

• Contact centre teams operate separately  

This leads to: 

• Inconsistent call handling  

• Poor interoperability between teams  

• Increased reliance on workarounds  

Over time, this impacts adoption and confidence in the system. 

Limited Scalability 

Every new requirement introduces more complexity. Whether it’s: 

• A new site  

• A new user group  

• A new workflow  

…each addition increases the management overhead. Without a unified approach, complexity grows faster than capability. 

Lack of Visibility and Control 

One of the biggest long-term impacts is the lack of visibility. 

Without a single view across the environment: 

• Troubleshooting is slower  

• Performance is harder to measure  

• Optimisation becomes reactive  

This aligns with what’s widely reported across the industry—communication gaps between frontline and central teams continue to impact efficiency, as highlighted in 

Why This Matters Now 

Research from Forrester Consulting shows that organisations using Microsoft Teams effectively for frontline workers can achieve a 25% reduction in operational errors over time. 

But from what I’ve seen, those benefits only materialise when communication is: 

• Integrated  

• Managed centrally  

• Aligned to how the business operates  

Otherwise, complexity offsets the gains. 

The Trends Shaping Manufacturing Communication 

Across the manufacturing organisations I work with, there are several consistent trends emerging. These aren’t theoretical, they’re driven by real operational pressure. 

1. Communication Is Becoming Core to Operations

With over 80% of manufacturers investing in digital connectivity (Deloitte, 2025), communication is no longer a supporting function. 

It’s becoming a core operational layer. 

This means communication systems now need to: 

• Support real-time decision-making  

• Integrate into workflows  

• Scale across sites and regions  

In practice, this shifts the requirement from “voice system” to operational communication platform. 

2. Hybrid Environments Are the Long-Term Reality

Despite efforts to standardise, most organisations are not consolidating into a single platform. 

Instead, they are: 

• Extending Microsoft Teams  

• Retaining legacy systems where needed  

• Supporting additional platforms such as Webex  

In one organisation I worked with, Teams had been successfully deployed globally, but regional teams continued using existing systems for operational reasons. 

Rather than forcing consolidation, the focus shifted to connecting those environments. 

3. Scale Is Increasing Faster Than Control

As organisations grow: 

• More users are added  

• More sites are connected  

• More systems are introduced  

But control mechanisms don’t evolve at the same pace. 

This leads to: 

• Increasing routing complexity  

• Reduced visibility  

• Slower change cycles  

This is often the tipping point where organisations realise their approach needs to change. 

4. AI Is Driving a New Set of Requirements

AI is beginning to reshape communication, particularly in areas like: 

• Intent-based routing  

• Workflow automation  

• Voice-driven interaction  

But AI introduces a new dependency: it requires connected systems. 

From what I’ve seen, organisations that haven’t addressed fragmentation struggle to adopt AI effectively. 

Those that have a unified environment are far better positioned. 

My Top Tips To Future-Proofing and Scaling In Manufacturing 

The organisations that get this right aren’t necessarily the ones with the newest technology. They’re the ones that take a structured approach to communication. 

1. Start with Operational Design

Before looking at technology, define: 

• How communication should flow  

• How escalation should work  

• How shifts impact availability  

In one organisation, mapping these workflows uncovered multiple inefficiencies that had nothing to do with the platform itself. 

2. Avoid “Rip and Replace” Thinking

In manufacturing, replacing systems outright introduces risk. Instead: 

• Keep what works  

• Replace where necessary  

• Connect everything together  

This approach aligns far better with how manufacturing organisations evolve. 

3. Introduce Centralised Control Early

Without centralised control: 

• Complexity grows  

• Changes become slower  

• Consistency becomes harder  

The earlier this is introduced, the easier it is to scale. 

4. Treat Routing as a Strategic Capability

Routing determines how the business responds. It should be: 

• Centralised  

• Flexible  

• Designed around real workflows  

5. Build Visibility Into the Core Design 

Visibility shouldn’t be an afterthought. It should be built into the architecture from day one.  

6. Design for Multi-Platform Environments

Microsoft Teams is central, but not exclusive. You need to account for: 

• Legacy systems  

• Contact centre platforms  

• Webex or other UC tools 

7. Prepare for AI

AI will increasingly influence communication. But it depends on: 

• Connected systems  

• Clean data  

• Centralised routing

 The Shift: Why Manufacturing Organisations Need a Centralised Communication Management Layer

In the environments where I’ve seen this approach implemented successfully, the turning point has been the introduction of a layer that sits above the individual systems—rather than trying to force everything into one. 

This is what I refer to as a management layer. Instead of replacing systems, it changes how they are managed. 

1. Connect Microsoft Teams, Legacy Telephony, and Contact Centres

Rather than removing Teams, legacy platforms, contact centres and carriers, it connects them into a single environment. 

2. Centralise Enterprise Routing and Communication Policies

Centralising control means routing, policies, and logic are managed in one place. This removes duplication, inconsistency and manual overhead. 

3. Create a Single Source of Truth Across Communication Systems

You gain end-to-end visibility, cross-platform insight, real-time reporting. 

4. Enable Scalable Change Across Global Manufacturing Environments

It enables scalable change. This is the biggest shift. Instead of making changes in multiple systems and coordinating across teams, you manage everything centrally. 

The Key Benefit 

From what I’ve seen, this approach aligns far more closely with how manufacturing organisations operate. 

It allows them to: 

• Modernise incrementally  

• Retain existing investments  

• Scale without adding complexity

Manufacturing Case Study In Practice: How Fortive Simplified Global Voice Management

Fortive is a strong example of how businesses are addressing these challenges in practice. 

Fortive was operating a highly fragmented voice environment, managing 12 carriers across different regions, alongside Microsoft Teams, legacy SIP infrastructure, a Five9 contact centre, and additional systems such as IVR and fax. With over 5,000 Teams users and high call volumes, this created significant complexity, with routing spread across multiple platforms and no central visibility. 

In this case, Fortive addressed this by introducing Callroute as a management layer across their existing environment. 

Rather than replacing systems, Callroute enabled them to connect all 12 carriers, integrate Microsoft Teams with legacy and contact centre platforms, and centralise routing into a single, consistent control layer. At the same time, it provided a unified view across their entire voice estate. 

The result was a shift from fragmented systems to a single, orchestrated environment – simplifying management, improving visibility, and enabling the business to scale without adding complexity.
