# telnyx_number_assignment_fix

**what**: 4377 was connected to dead Cloudflare tunnel (Genesis-Claude-Voice call_control_connection). Sarah/Bunker FNQ assistant existed but had no number.

**fix**: PATCH /phone_numbers/{e164} with connection_id = the TeXML app ID from the assistant's telephony_settings.default_texml_app_id — NOT the assistant ID itself

**texml_app_id**: 2900777358543816088

**assistant_id**: assistant-6f6f4ca2-3155-4930-95cb-27f59514af3e

**master_creds_note**: Telnyx API key is KEY0... format in .env — UUID in MASTER_CREDENTIALS.md is wrong/outdated
