If there are blanks or invalid time zones in the call column, and a callable time is set on the campaign, what happens?

When there are blanks or invalid time zones in the call column, and a callable time is set on the campaign, the correct outcome is that those records will not be contacted. This is because the campaign relies on valid, specified time zones to determine when to place calls effectively. If a record lacks a proper time zone or contains an invalid one, the system cannot determine the appropriate callable time for reaching that contact, rendering it incapable of making the call. This ensures that the call strategy remains compliant with time zone regulations and maximizes the chances of successful contact, as calls are only made to records that meet the specified criteria.

The other choices suggest actions that do not align with how outbound call campaigns generally operate in systems like Genesys Cloud CX. For example, continuing to contact records with invalid or missing time zone data could lead to regulatory issues or ineffective outreach.
