We turn PBX partners into Teams Phone partners.

Making Teams Phone Feel Like a PBX Again — and Unlocking a New Channel

For years, thousands of businesses have relied on local and hosted PBX systems like 3CX, Mitel, Avaya, and similar platforms. Around them sits a large, capable ecosystem of installers, maintainers, and service providers who understand voice — and understand small businesses.

Microsoft Teams Phone changes the destination.

But it doesn’t change the people responsible for keeping phones working.

The problem: Teams doesn’t look like a PBX

For many PBX-focused partners, Teams Phone presents a barrier:

• The Teams Admin Center is unfamiliar and complex

• Configuration is spread across multiple Microsoft portals

• Routine PBX tasks don’t map cleanly to Teams concepts

• Supporting customers requires deep Microsoft tenant access

As a result, many capable voice partners hesitate — not because they lack skills, but because Teams Phone doesn’t feel like the PBX systems they manage every day.

A familiar control panel for a new platform

Haptap Call Manager changes that.

Call Manager presents Teams Phone through a PBX-style control and configuration interface, making it immediately accessible to:

• PBX installers and maintainers

• Voice-focused MSPs

• SMB telephony specialists

Day-to-day tasks — users, numbers, call flows, queues — are managed in a way that feels familiar, even though Microsoft Teams remains the underlying platform.

A new route to the Teams Phone market

This opens up a significant opportunity.

Many existing PBX partners:

• Already support SMB customers

• Already manage voice services

• Already have trusted customer relationships

As those customers increasingly use Teams every day, Teams Phone becomes a natural next step — for convenience, simplicity, and consolidation.

Call Manager allows PBX partners to participate in that transition without becoming Microsoft specialists.

Why operators should care

For operators delivering Operator Connect or Direct Routing, this channel is powerful:

• Deep SMB reach

• Strong voice expertise

• Proven service relationships

By pairing operator-grade voice services with a PBX-familiar control experience, operators can:

• Extend their reach through an established channel

• Preserve service quality

• Accelerate Teams Phone adoption in the SMB market

The bigger picture

Teams Phone doesn’t replace the PBX ecosystem.

It evolves it.

The winners will be those who make Teams Phone feel familiar, easy to manage, and accessible to the people who already run voice services today.
