| - **From your records to Fish Audio**: take the `Call-ID` from your CDR and list sessions with `GET /v1/agent/sessions?sip_call_id=…`, which returns the matching session. If your SBC logs custom headers, `X-Fish-Session-Id` from the INVITE gives you the session id directly. |

Qualify carrier-CDR lookup for unanswered outbound calls.
The nearby call-type table states that an unanswered outbound call has sip_call_id: null, but the lookup instruction still says that the filter returns the matching session without this condition. An INVITE Call-ID from an unanswered outbound call therefore cannot find the session through sip_call_id. Qualify all three descriptions to apply only when the session stores sip_call_id. Keep X-Fish-Session-Id as the alternative when the SBC or PBX logs it.

| - An empty password next to a set username keeps the stored password, so you can edit other fields without re-entering secrets. Setting a username for the first time requires a password. | ||
| - An empty `termination_uri` removes the termination and makes the number inbound-only again. | ||
| - `termination_headers` replaces the stored map; omit it or send `{}` to remove all custom headers. |

Align the SIP configuration update contract with the documented request.
The OpenAPI document has no PUT /v1/agent/phone-numbers/{phone_number_id}/sip-config operation. Its only phone-number update operation is PATCH /v1/agent/phone-numbers/{phone_number_id}, which uses PublicPhoneNumberUpdatePayload and does not define termination_headers. Generated clients therefore cannot represent the documented update.
Add termination_headers to the request schema for the supported update operation and document that operation, or change the guide to use the existing request contract.

Align the documented voice.expressive default with the schema.
This description says the default is true, but AgentVoiceConfig.properties.expressive specifies false. Confirm the effective default and correct the conflicting value so users know whether they must enable expressive delivery.
