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.

Each person can also connect their own Google account:

  • Sign in with Google or Microsoft: existing, active users can continue with Google or Microsoft instead of typing a password, when turned on for your account.
  • Google contacts: copy your Google contacts into your personal contact list, so those callers are named when they ring.
  • Google Calendar: your Google Calendar events join your meetings agenda.
  • Gmail: recent Gmail threads show beside each contact, so you have context before you call back.
  • Read-only and reversible: Google access is read-only, and it is removed when you disconnect.

Or use what's built in

Some teams already have Teams or Workspace for meetings and chat, and that works well alongside us. Others would rather keep everything in one place. Cannon VoIP includes its own video meetings, team chat, calendar and a built-in CRM in the same portal and apps as your phone system.

Video meetings
A permanent room link for your business, a waiting room, screen sharing, recording, and dial-in from any phone. Guests join from a browser with no account.
Team chat
Team channels, private channels and direct messages, with channel roles (Admin, Member or View only). Reply to a message, react to it, see who has read it, attach files, or write now and send later. New messages appear live, team chat works in the Android and iPhone apps too, and it shares one Messaging tab with your business texts.
Calendar
Month view and agenda in the portal and the Android and iPhone apps. Add a video meeting with a Join button to any new event, or subscribe from Google Calendar, Outlook or Apple with a private link.
Presence everywhere
Colleagues show live status like At lunch or On a call across the portal and apps, so you know who is free before you call.
Built-in CRM
People, companies, deals and pipelines, included in the $34 per extension price. Connect each person’s own Gmail or Microsoft 365 mailbox, so mail leaves from their real account and replies come back to their inbox. More on the CRM.
Appointments
Book, move and confirm appointments, with a public booking page, a confirmation text when booked and a reminder before. Appointments show on the portal calendar.

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.
