Microsoft Teams Calling for business

Microsoft Teams connects your people. We connect the calls that keep business moving.

We provide integrated PSTN calling for Microsoft Teams in 80+ countries, backed by enterprise-grade infrastructure and voice solutions built to match the way people work today.

You get full flexibility with Operator Connect or Direct Routing, backed by a team that knows how to design and support complex deployments. This isn’t off-the-shelf. It’s voice built for the way your business actually works.

We’ve been doing this for over 15 years. We’ve worked with everything from legacy PBXs to hybrid cloud environments and compliance-heavy sectors. When the setup is complex or the region is difficult, we step in where others tend to step away.

You work directly with experienced engineers, not ticketing systems. From initial planning through to live service, we stay hands-on because that’s what makes the difference.

Choose the right path

Direct Routing

For more complex voice environments, Direct Routing offers full control and flexibility. You can connect your existing SBCs, SIP trunks, and voice architecture to Microsoft Teams, with room to customize every part of the setup.This path is often the right fit for enterprises with regulatory constraints, on-prem systems, or integration needs that Operator Connect can't fully support. We handle the architecture, deployment, and ongoing management so your team doesn’t have to.

Operator Connect

If you're looking for simplicity at scale, Operator Connect offers a direct route. You can assign numbers and manage users through the Teams Admin Center while we take care of the provisioning, infrastructure, and support. It’s a streamlined option that gets you up and running quickly without sacrificing control or coverage.Ideal for organizations rolling out Teams Phone across multiple regions or looking to replace legacy contracts with a single global provider.

Testimonials

I know that at any point I can pick up the phone and immediately get through to someone on Pure IP. [Pure IP’s work] was done extremely well, to a very high standard and the delivery was excellent. Now we have the cloud service we need operating perfectly.

Pure IP has been an instrumental partner in the global telephony migrations I have worked on over the past few years. Their expertise and services have been a key driver in streamlining what is sometime a complex journey to Microsoft Teams. By moving to Operator Connect with Pure IP, the businesses I’ve worked with have significantly reduced their dependency on on-premise telephony, making operations much more efficient. Their support has been invaluable in these transitions.
