The requirements point to tenant-wide recording with the least custom design. Cisco's Webex Contact Center voice settings include a global call recording setting that records all inbound and outdial calls when enabled. That setting is administered centrally, which matches the requirement that only administrators configure recording and that recordings apply to the entire company. Flow-based recording is more flexible, especially when consent or conditional recording decisions are required, but it is custom logic and not the simplest global policy. Queue-level configuration is useful when different business lines need different recording behavior, but this scenario explicitly says all inbound calls across the company. Scheduled recording is suitable when recording depends on a time window, queue, team, site, or agent scope. Since the company wants all inbound calls recorded and wants to avoid custom configurations, global configuration is the cleanest Cisco-supported method.
