# Fax

Fax-channel option payload for Document API distribution.

> **Compilation status:** This type is defined in `Business\SAIF.Business.Policy.Audit.ApiCalls\DistributionMethod.cs`, which is present in this library's source directory but is **not** listed in the `<Compile>` item group of `SAIF.BOF.Business.Policy.Audit.ApiCalls.csproj`. It is a source-included artifact and is not part of the compiled `SAIF.Business.Policy.Audit.ApiCalls` assembly's public surface.

## Purpose
- Describe fax recipient details, cover-sheet text, and attachment naming for fax delivery.

## Context
- Namespace: `SAIF.Business.Policy.Audit.ApiCalls`
- Assembly/package: `SAIF.Business.Policy.Audit.ApiCalls`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| DistributionMethodType | `public string DistributionMethodType { get; }` | Exposes `Fax` as the discriminator for this delivery-channel payload. |
| AttachmentFileName | `public string AttachmentFileName { get; set; }` | File name assigned to the faxed document. |
| CoverSheetNote | `public string CoverSheetNote { get; set; }` | Note text printed on the fax cover sheet. |
| ToCompanyName | `public string ToCompanyName { get; set; }` | Recipient company name shown on the fax cover sheet. |
| ToFaxNumber | `public string ToFaxNumber { get; set; }` | Destination fax number the document is sent to. |
| ToName | `public string ToName { get; set; }` | Recipient name shown on the fax cover sheet. |
| ToPhoneNumber | `public string ToPhoneNumber { get; set; }` | Recipient phone number included for fax-delivery follow-up.* |

## Behavioral notes
- The class inherits `DistributionMethodType` from `DistributionMethod<Fax>`.

## Constraints and usage notes
- Phone-number validation and delivery handling are delegated to the downstream service.

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or
> contextual evidence where direct confirmation was not available in source artifacts. Statements
> marked with ** could not be confirmed; treat as unknown until verified.
