RingCentral Pin Verification | Web Hosting Talk

Does anyone in these forums have experience with RingCentral (or any other phone service) that includes automated PIN verification?

We want to develop a functionality in WHMCS that will randomize customers who want to call and look for a system that we can use (ideally RingCentral because we're currently using it) that has some kind of add-on or API functionality Provide support pin available where the system can automatically check the caller before connecting to the operator.

We would appreciate feedback.
