The order of PSTN usages in a voice routing policy is critical: usages are evaluated in order and, once a match is found in one usage, later usages are never evaluated, so a catch-all usage such as International must be placed after more specific usages.

Checked 2026-09-30

The usages are applied in order, and if a match is found in the first usage, then other usages are never evaluated.
