Calling in Webex Teams (Unified CM) OverviewThe Calling in Webex Teams (Unified CM) solution lets you register Webex Teams directly to your CiscoUnified Communications Manager call control environment (on-premises enterprise, Business Edition6000/7000, or as delivered through an HCS partner solution).

In softphone mode, Webex Teams registers as a SIP device with the product type "Cisco Unified ClientServices Framework" or CSF for desktop, TCT or BOT for mobile, and TAB for tablets. Alternatively, WebexTeams can connect to Unified CM using CTI to control the user's endpoints.

This solution enhances the calling experience for end users, allowing them to directly make calls in WebexTeams through your Unified CM environment, use midcall features, and control their Unified CM registereddesk phone from Webex Teams.

When dialing from Cisco Webex Teams, users can use the same dial strings or prefixes as they do on theirdesk phones; CiscoWebex Teams functions like any other desk phone registered to your Unified CM. UnifiedCM calls that are established in Webex Teams use the configuration that's in place for your Unified CMdeployment (such as location, bandwidth settings, point to point media, and so on).

Calling Features for Calling in Webex Teams (Unified CM)This integration provides the following feature set in Webex Teams for desktop (Windows and Mac) and formobile (Android, iPad, and iPhone). Wherever possible, the feature listings in this table include a link to a

Desk Phone Control for Webex Teams for Windows and Mac

Any desk phones or Extension Mobility profiles that are associated with the user's Unified CM account arelisted as an available device to connect to in Webex Teams for Windows or Mac. If the device is selected,Unified CM calls that are dialed from or answered in Webex Teams use that desk phone. Users can start orstop the call, enter DTMF input (which the phone acknowledges), and use the midcall features that aredocumented in the preceding feature table. Users can also join meetings from Webex Teams in desk phonecontrol mode.

Joining a meeting while paired through Room, Desk,or Board devices

Desk phone control calls (outgoing: dial a directoryor PSTN number in Webex Teams, take the call onthe Unified CM device; incoming: answer the call inWebex Teams, take the call on the device).

1:1 calls that are placed directly in Webex Teams toa free user in the consumer organization, to a user inanother organization, or to a user in the sameorganization who doesn't have a directory number.(Numbers are not shared across organizations, so don'tappear in contact cards.).

User Experience Changes for Hybrid Call Service UsersFor users who are paired to a cloud-registered Room, Desk, or Board device:

• Unified CM registration in the Webex Teams app stays active.

• Incoming calls to a user's directory number are presented in Webex Teams and, when accepted,calls are answered on the desktop app and do not use the paired Room, Desk, or Board device.

• If the Webex device is configured in Control Hub as a Place that is enabled for Hybrid Call Service,the user can dial fromWebex Teams and the call then starts on the Webex device using that device'sdirectory number as the caller ID on the receiving end.

• If the Webex device is not in a Place that's enabled for Hybrid Call Service, the directory numberor PSTN dialing fails and an error message is presented in the user's Webex Teams app.

For users who are in desk phone control mode in Webex Teams:

• Media (audio and video) for 1:1 calls to users with contact cards and calls that are started from thesearch or dial view go through the on-premises desk phone.

• Media (audio and video) for group space meetings, Webex meetings (scheduled or ad-hoc), andcalls to users without contact cards go through the Webex Teams desktop app.

For scenarios involving a call going to voicemail:

• Incoming calls that don't go through Unified CM do not roll over to voicemail and continue to ringuntil the user answers or declines.

• Incoming calls that go through Unified CM (for example, to a user's corporate directory numberroll over to voicemail.

Protocol Handlers for CallingCalling in Webex Teams (Unified CM) registers the following protocol handlers with the operating systemto enable click-to-call functionality from web browsers or other applications. The following protocols startan audio or video call in Webex Teams when it's the default calling application on Mac or Windows:

• CLICKTOCALL: or CLICKTOCALL://

• SIP: or SIP://

• TEL: or TEL://

• WEBEXTEL: or WEBEXTEL://

If Unified CM is not connected when the app is launched for these protocols, Webex Teams waits threeminutes for Unified CM to connect. If three minutes passes with no connection, the call request stops. If usingSIP address to start a call (for example, sip:test@example.com), the call may go through the cloud orUnified CM, depending on your organization's SIP address routing configuration in Control Hub.
