Your Phone System, Where You Already Work

Real calls inside Teams, sign-in with Microsoft 365, and directories that keep themselves current from Workspace.

Published August 7, 2026 · Cannon VoIP Team

If your company lives in Microsoft Teams or Google Workspace, your phone system shouldn't feel like a separate world. Cannon VoIP connects to all three of Microsoft's and Google's productivity layers, Teams, Microsoft 365, and Google Workspace, so calling, contacts, and sign-in follow the tools your team already uses all day.

Real phone calls, inside Microsoft Teams

Through Direct Routing, your Teams users can make and receive real phone calls, actual business numbers, not just Teams-to-Teams chat calls, using Cannon VoIP for connectivity instead of buying Microsoft calling plans. We host and maintain the carrier-grade routing infrastructure centrally; your team just sees a dial pad in Teams that works.

What Microsoft 365 connection adds

Single sign-on
Sign in to the portal and apps with your existing Microsoft account instead of another password to manage.
User sync
New hires added in Microsoft 365 / Entra ID show up in the phone system automatically, no double data entry when someone joins or leaves.
Contact sync
Personal and shared-mailbox contacts appear in your phone system's directory, so callers are recognized and colleagues are a click away.
Notifications through your own mail
Voicemail and system emails can be delivered through your own Microsoft 365 tenant via OAuth, from your domain, through your mail flow.

And for Google Workspace shops

The same idea, Google-flavored: contacts and users sync from Google Workspace so your directory stays current on its own, when someone's added or updated in Workspace, the phone system already knows.

Setup happens with our team, connecting either platform takes an admin consent step on the Microsoft or Google side, and we walk through it with you during onboarding. Also connected: 11 CRM and helpdesk platforms.

Teams calling is a favorite of the firms on our law firm page, worth a look if that is your world.
