# ProvisionVoicePhoneNumberSMSAPI mirrors erdo_voice_phone_number_sms_provision:


> it files the SAME approval-gated action the chat agent files — same action key, same input, same dedupe subject, same card — so /v1 is never a second ungated way to spend money at a carrier registry. A \`pending\_approval\` response means a card now awaits a human and nothing was registered.
