Real Phone Calling, Native to the Teams App Your Staff Already Use
Enterprise calling inside Teams, at a fraction of what Microsoft charges per seat for Calling Plans.

Your team already lives in Teams for chat, meetings, and files. We connect enterprise-grade voice directly into that same interface — a real Microsoft Teams voice integration, not a bolt-on app — so making and receiving real phone calls feels native, without the per-seat cost of Microsoft Calling Plans, and without losing the call center features Calling Plans don’t include at all.
What This Microsoft Teams Voice Integration Includes
Dial and answer directly from the app your staff already have open.
Priced to make sense at 50, 100, or 250+ seats, the larger you are, the bigger the gap.
A Hamilton-area team handles setup, changes, and support, not an offshore ticket queue.
Microsoft’s own Calling Plan add-on works, but it prices per seat with limited call center features layered on top for an extra fee. A dedicated Microsoft Teams voice integration through UCSTAK starts from the phone system side instead, so routing, queuing, and recording come standard rather than as upsells.
Setup doesn’t touch your existing Teams tenant configuration in any risky way. Numbers port over on a schedule you control, and staff keep using the same Teams client they already have open all day — there’s no separate softphone app to install or train anyone on.
If you’re already comparing vendors, ask what happens to call recording, queue reporting, and IVR menus once you’re inside Teams. Those features are often where a bare-metal Microsoft Teams voice integration and a full managed phone system diverge the most.
