When your Microsoft Teams account is connected to your CallHarbor phone service, you can make and receive business calls directly in Teams. This article shows which calling features are available to you.
There are two ways features are delivered:
- Built into Teams. These work in the standard Teams calling screen with nothing extra to install.
- The CallHarbor app for Teams (optional). Adding the app inside Teams gives you extra phone system features, such as voicemail and star codes.

Extra features with the CallHarbor app for Teams
If the app has been added to your Teams, you also get:
| Feature | Good to know |
|---|---|
| Voicemail alerts | See when you have a new voicemail |
| Voicemail access | Listen to your voicemail inside Teams |
| Star codes | Use them before or during a call |
| Shortcut buttons | One-click buttons for the features you use most |
| Quick commands | Type a slash command in Teams to trigger a feature |
| Phone portal access | Open your CallHarbor user portal from inside Teams |
| Call back | Return a call straight from the call card |
| Schedule a meeting | Set up a Teams meeting with the caller from the call card |
| Save a contact | Add the caller to your contacts from the call card |
Things that work differently than a desk phone
- Hold music. Callers on hold from Teams hear the Teams hold music, not your company's phone system hold music.
- Park. Parking a call in Teams uses the Teams park feature, so the steps differ from parking on a desk phone.
- Adding outside callers. If you can't add an outside number to a call or meeting, ask your Microsoft 365 administrator whether you have Teams Audio Conferencing.
- Voicemail. If you don't see voicemail in Teams, the CallHarbor app may not be installed for you yet.
