Customer XYZ has deployed Bring your own PSTN option to route calls to his Webex...

A reorder tone followed by call drop at call ingress is usually a telephony signaling or trunk acceptance symptom, not an Analyzer or queue-configuration symptom. In a Bring Your Own PSTN design, the customer's PSTN carrier and session border controller are responsible for delivering calls toward Webex Contact Center through the agreed voice path. Cisco's Webex Calling and Local Gateway documentation emphasizes trunk status, SIP connectivity, registration or certificate state, and SBC reachability as the first checks when calls fail before application routing. If the call cannot be successfully established across the customer's SBC or Local Gateway, Webex Contact Center will not have a usable interaction to queue, analyze, or route. Analyzer becomes useful after the platform has received enough call data to create records; it is not the first place to diagnose a reorder tone at ingress. Channel and queue association should still be reviewed later, but the symptom points first to SIP trunk status on the SBC.
