Abstract
Techniques are described herein for blocking robo-calls, spam calls, and telemarketing calls, which are becoming an industry menace. Such calls are blocked by tightly integrating a Software-Defined Networking in a Wide Area Network (SDWAN) controller with a Do Not Call registry. Analytics are used to analyze traffic call patterns, security insights are leveraged such as known malicious Internet Protocol (IP) and domain addresses, and a Call Barring feature may also be applied. This information may be pushed to edge devices to ensure robo-calls do not terminate on SDWAN-led voice endpoints.
