SENTRY is designed to authenticate a call between the originating phone number and the intended called party. When a call is forwarded through an additional routing step, the original authentication pairing may no longer be maintained.
As a result, SENTRY's behavior in enterprise call forwarding scenarios cannot be definitively guaranteed. If your organization uses complex call routing or forwarding workflows, we recommend discussing the specific use case with your First Orion account team to determine the best approach.
