Large organisations rarely have one carrier. This course covers how to connect several SIP providers across regions through CUBE, and how to route calls between sites, platforms and carriers predictably.
You will build a multi-site, multi-carrier design with least-cost and resilient routing, then prove it under failure in the lab.
12 h video + 18 h labs, about 3 weeks at 6–8 hours per week.

“We consolidated six carriers using the design method from this course.”
“The failover lab exposed a gap in our production design before a carrier outage did.”
