[cisco-voip] How difficult is hybrid call (connector) setup ?

Tue Jul 2 23:01:59 EDT 2019

I would highly recommend watching this CiscoLive session: "Cisco Webex
Hybrid Services (formerly known as Spark Hybrid Services) Call Service
Connect Architecture and Design - BRKCOL-2202"

Luca does a great job explaining how it all works.
