Customer XYZ has deployed Bring your own PSTN option to route calls to his Webex Contact Center environment. Callers calling in are reporting getting a reorder tone followed by a call drop.

Which action helps to identify the cause of the issue?

Show Suggested Answer Hide Answer
Suggested Answer: A

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.

A is solid, but B is important too. Channels need to be linked.

I think option A is the best choice. SIP trunk status is crucial.

Wait, why would they get a reorder tone? Sounds odd!

I wonder if looking at the Queues configuration could help. I vaguely recall something about how misconfigurations there can lead to call drops, but I need to double-check that.

Reviewing the call logs with the Webex Contact Center Analyzer sounds like a solid option. I feel like that could give us more insight into what's happening with the calls.

I remember a practice question where we had to verify channel associations in Webex. That might be relevant here too, but I'm not confident it directly addresses the call drop issue.

I think checking the SIP trunk status on the Session Border Controller could be a good first step, but I'm not entirely sure if that's the only thing we need to look at.
