# Time zone and call analysis are guarded defaults · Learn it in 5 minutes

- The campaign admin tree includes time zone dialing options, and the default-settings topic says call analysis and voice detection level ship with vendor defaults. Changing defaults can raise a compliance warning. The same topic says US domains watch abandon rate for 30 rolling days and UK domains for 24 hours, and that a Five9 representative sets which kind of domain you have.
- This lab will not invent the legal calling window or the numeric abandon default. Both move, and both are jurisdiction-specific. Open the current page and the current rule before you widen either one.
