Many enterprises run CUCM and Teams side by side. Cisco CUBE can be the single SBC connecting both to carriers and to each other.
In this course you will pair CUBE with a real Microsoft 365 tenant, configure the Teams-specific SIP and TLS requirements, enable media bypass, and route calls between Teams users, CUCM phones and the PSTN.
10 h video + 14 h labs, about 3 weeks at 6–8 hours per week.
