Webex Teams Calling Cucm



Full Demonstration of Integration between Cisco Unified Communications Manager and WebEx Calling. Includes the Cisco Webex Calling service for cloud-based calling, Cisco Webex client application, Cisco Directory Connector for identity integration, and Local Gateway IOS-XE router for PSTN access as well as on-premises to cloud calling integration. Cloud Connected PSTN (CCP) facilitated by a provider partner is another option for PSTN access. The first option is purely cloud based ie Webex Teams app uses whatever webex calling plans you have, Ie if you have Webex calling (with Local gateway) enabled you can still make calls to CUCM and PSTN. The second option registers your webex teams app to CUCM as a CSF device. Can also leverage MRA to register off premise. Cisco Webex Calling ensures your team calls are high-quality, cross-platform, and reliable. Free online cloud calling, video conferences, audio calls.
