A widget that executes background logic without presenting a visible user-interface panel belongs in the Headless area of the Agent Desktop layout. Cisco's custom desktop layout framework separates visible layout regions, such as panels or persistent areas, from headless widgets that run logic in the background. The requirement says the custom widget should trigger a CRM screen pop when an SMS arrives. That is event-driven background behavior; the agent does not need to see a standalone widget tab or panel for the code to work. A Panel object would be appropriate for visible content placed in the desktop interface. Navigation is used for navigation entries or visible application areas. Persistent is for UI that remains visible across desktop contexts. Headless is deliberately designed for invisible logic, event listeners, and background integrations that react to contact events, making it the correct object for this SMS-triggered CRM screen-pop logic.

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.

The registration refresh interval is derived from the expires value multiplied by the refresh ratio. In Cisco IOS XE Local Gateway configuration for Webex Calling, the registrar command commonly uses an expires value and a refresh-ratio. With expires 240 and refresh-ratio 50, the gateway refreshes registration at 50 percent of 240 seconds, which is 120 seconds, or exactly two minutes. Option B uses refresh-time, which is not the documented parameter used in the provided command style. Option C would refresh at 60 seconds because 50 percent of 120 is 60. Option D would refresh at 150 seconds because 50 percent of 300 is 150. The correct answer is therefore the command that sets expires to 240 with refresh-ratio 50 over TLS using the sips scheme. This aligns with Cisco's registration-based Local Gateway model, where the SBC must keep SIP registration active toward Webex Calling.
