Overview of Hybrid Call Service
When deploying a new service for your users that connects your Unified CM calling environment with the cloud, we strongly encourage you to deploy Calling in Webex Teams (Unified CM). The newer service closely follows familiar Jabber deployment models where Webex Teams registers directly to Unified CM as a soft phone. No extra Expressway connector infrastructure nor firewall traversal capacity is required beyond what is needed for remote access (MRA). Hybrid Call Service is still the recommended deployment model for providing cloud-registered Webex video devices with a Unified CM directory number or extension.
With Hybrid Call Service, you can get the capabilities of Cisco Webex services but also continue to use Cisco Unified Communications Manager, Business Edition 6000 or 7000, or a Cisco Powered™ cloud service from a certified Cisco Hosted Collaboration Solution partner for call control. Hybrid Call Service integrates your call control so tightly with Cisco Webex Teams Message and Cisco Webex Meetings that your end users will never know they are not a single service. It connects the Cisco Webex cloud calls and the unified communications system so that they work together.
With Hybrid Call Service, your users can
Make calls from their desk phones or the Cisco Webex Teams app using the same dial plan
Receive incoming calls in both their desk phones and the Cisco Webex Teams app and answer the call on either
