In this article, you’ll learn:
- Why adding cloud voice is now significantly easier for UK MSPs, when the right channel‑first partner is in place.
- How PSTN and ISDN switch‑off pressures are accelerating voice migration, and what MSPs should prioritise to reduce risk and disruption.
- What to look for in a UK channel‑first communications provider, beyond products alone, including migration support, enablement, and operational simplicity.
- How MSPs can add voice to their portfolio without increasing operational overhead, while improving customer stickiness and recurring revenue.
MSP customers are shifting to hybrid work, AI‑enabled workflows and secure, cloud‑based communications at speed. The global UCaaS market is currently estimated to be worth $78.2 billion and is forecasted to grow to $276.9 billion by 2034. Demand is continuing to rise and MSPs must meet that need with ease.
But growth also comes with increased pressure. MSPs are faced with the prospect of migrating legacy estates, protecting margins, simplifying operations and meeting rising expectations around compliance and security. It has the potential of making the choice to adopt voice solutions complicated.
These pressures make partner choice one of the most important strategic decisions an MSP can make. The right vendor relationship isn’t simply about incorporating more products. Relationships are built on t’s about clarity, predictability, and support that removes both friction and reduces operational risk.
Voice migration made simple
Migration is often the biggest barrier MSPs face. As John Murphy, CEO of Gamma Business, said in Gamma’s 2026 Partner Kick Off webinar:
“Partners need to be able to focus on new business while migration happens in the background, not instead of it.”
With the PSTN switch off set for 2027, there are over 500,000 business lines that still rely on analogue services. If MSPs want to protect their customers from any unnecessary disruption, their needs to be support and guidance in place to make migration seamless.
Vendors should be carrying the operational weight, rather than passing it on to their partners. Frameworks such as Gamma Edge include the Migrate pillar, which simplifies legacy transformation that reduces strain on resources. Solutions are modernised with minimal risk, allowing MSPs to enjoy a lighter workload while enhancing customer stickiness.
Onboarding, training and sales support
If MSPs want to add voice to their portfolio, they’ll need the right amount of support. In turn, this support needs to feel human and useful. But above all, it must be simple to action.
The best kind of partnerships are the ones that remove friction at every stage. That’s what defines the difference between a partner and a vendor.
Dedicated onboarding support from sales specialists allows MSPs to sell, deliver and scale with confidence. These partners need to enable, rather than just supply.
73% of MSPs anticipate their revenue to increase in the coming years, yet fears remain over operational constraints and complexity. Simultaneously, 98% of organisations would be exposed If their MSP was subject to a cyber security incident. This reflects how MSPs need to adopt compliance-aligned voice solutions that minimise risk and safeguard communications.
Gamma’s partner‑first philosophy aligns strongly with these expectations. Listening, understanding and responding means there are clear outcomes MSPs can repeat in a customer conversation.
When backed by practical enablement, structured support, and a consistent voice, this kind of clarity reduces friction and helps MSPs win more deals with less effort.
The importance of brand relationships
Modern MSPs want partners with credibility and influence. They need to be resilient to help MSPs meet rising customer demands for security, compliance, and platform stability.
Gamma’s global brand relationships, especially with the likes of Cisco, give MSPs direct influence over UCaaS product evolution. Close collaboration with Cisco’s Executive Committee shapes roadmaps around products such as Webex for Gamma allows MSPs to benefit from a roadmap tailored to their needs.
Long-term success is never based solely off enterprise priorities.
The established partner community also helps shape roadmaps through aggregated feedback and AI-driven insight tooling. Co-development via Product Advisory Boards means future innovations are shaped with partners in mind.
MSPs, when working alongside Gamma, get a vendor that listens and acts with transparency. The real value lies ‘below the waterline’, with regulatory knowledge and governance being a key differentiator as security and compliance become more important.
Big-brand influence, strong compliance, a partner-shaped roadmap, and global reputation all create a more trusted, influential ecosystem for MSPs. It’s never just about technology.
Voice: A low-effort, high-return opportunity for MSPs
MSPs who choose to add voice today aren’t stepping into complexity. They’re arriving at one of the most profitable, strategically aligned parts of the cloud stack.
With the right partner, migration becomes background work. Compliance turns into an advantage, alongside the big brand relationships that differentiate propositions. MSPs gain certainty over roadmap direction with every conversation, and growth becomes a predictable entity.
Gamma’s partner‑first approach ensures that MSPs can sell more, grow faster, and operate with less friction. Backed by a vendor who listens, responds, and continually invests in partner success, the opportunity to add voice is easier than ever.
No matter where an MSP is on their voice journey, the path forward is simpler, clearer and far easier to scale.
Quick Answers: Why Adding Voice Is Easier Than Ever With the Right Partner
What does it mean to add voice services as an MSP?
Adding voice services typically means offering cloud‑based business telephony — such as hosted PBX, SIP trunking, or Microsoft Teams voice — alongside existing IT, connectivity, and managed services. For MSPs, voice becomes part of a broader communications stack rather than a standalone product.
Why is voice easier for MSPs to add now than in the past?
Voice is easier to add today because modern UCaaS platforms, operator‑led migration tools, and partner enablement programmes reduce the technical and operational burden on MSPs. When migration and compliance are handled by the provider, MSPs can focus on selling and customer outcomes instead of delivery complexity.
How does the PSTN and ISDN switch‑off affect MSPs and their customers?
With the UK PSTN switch‑off approaching, many businesses still rely on legacy phone systems. MSPs are under pressure to help customers migrate to cloud voice without disruption. Providers that invest in large‑scale migration frameworks and guidance make this transition far simpler for partners and end customers.
What should MSPs look for in a voice partner?
MSPs should look beyond pricing and features and assess whether a provider is truly channel‑first. Key factors include migration support, onboarding and training, sales enablement, compliance expertise, and a clear product roadmap shaped by partner feedback, not just enterprise demand.
Is adding voice still profitable for MSPs?
Yes. Voice remains one of the most commercially attractive parts of the cloud stack when delivered correctly. It supports recurring revenue, increases customer stickiness, and often acts as a foundation for wider communications and managed services conversations.
How does a channel‑first provider make voice simpler to sell?
Channel‑first providers are built around reseller success. They invest in enablement, migration tooling, and partner programmes that remove friction at every stage, from presales to deployment, making voice easier to position, deliver, and scale.
