Update Call becomes ended-calls-only

This deprecation is scheduled for 08/31/2026. Review the migration guide below and update your integration before the sunset date.

The override_dynamic_variables input on Update Call is deprecated, and Update Call becomes ended-calls-only. Changes made through Update Call, including data_storage_setting, now apply only to ended calls. Use the new Update Live Call API to override dynamic variables or change data_storage_setting on ongoing calls.
