FAQ: Will BYOC support inbound trunk redundancy and failover?
BYOC allows customers to define multiple trunks, potentially to more than one carrier. Should a carrier or trunk experience an outage, calls inbound on these trunks would fail. The remaining trunks would continue to route calls in to Genesys Cloud.
However, many carriers support carrier-level failover, which you can leverage to redirect calls to alternate trunks.
