README

Framework-agnostic PHP library for parsing FreeSWITCH mod_xml_curl request fields and rendering package-owned directory XML projections.

Boundary

APNTalk owns authority. FreeSWITCH owns provider-local runtime behavior. This package owns only XML projection.

v0.1.0 is intentionally narrow:

• Directory sip_auth parsing and projection only.
• Reverse-auth, message-count, gateways, and network-list are parsed only enough for the caller to return not-found XML.
• No Laravel dependency.
• No Symfony dependency.
• No PSR-7 dependency.
• No APNTalk core dependency.
• No database, HTTP client, filesystem writes, or FreeSWITCH ESL behavior.

Install

composer require apntalk/freeswitch-xml-projection

Usage

<?php

declare(strict_types=1);

use APNTalk\FreeSwitchXmlProjection\Directory\A1HashCredential;
use APNTalk\FreeSwitchXmlProjection\Directory\DirectoryDocument;
use APNTalk\FreeSwitchXmlProjection\Directory\DirectoryDomain;
use APNTalk\FreeSwitchXmlProjection\Directory\DirectoryParam;
use APNTalk\FreeSwitchXmlProjection\Directory\DirectoryUser;
use APNTalk\FreeSwitchXmlProjection\Directory\DirectoryXmlRenderer;
use APNTalk\FreeSwitchXmlProjection\Http\XmlCurlRequestParser;

$request = (new XmlCurlRequestParser())->parse($_POST);

if (! $request->isDirectory() || $request->action()?->value !== 'sip_auth') {
    return;
}

$document = new DirectoryDocument([
    new DirectoryDomain(
        'tenant.example.test',
        [DirectoryParam::dialStringDefault()],
        [],
        [
            new DirectoryUser(
                '1001',
                A1HashCredential::fromPlainPassword('1001', 'tenant.example.test', 'secret'),
            ),
        ],
    ),
]);

echo (new DirectoryXmlRenderer())->render($document);

Security

• Prefer a1-hash over plaintext password.
• Never log rendered XML containing live credentials.
• Basic auth, mTLS, IP allowlists, rate limits, and audit logging belong at APNTalk's HTTP edge, not in this package.

See docs/security.md.

Fixture provenance

tests/Fixture/Requests/real-directory-sip-auth-redacted.php is based on a real redacted FreeSWITCH Docker mod_xml_curl directory sip_auth capture from 2026-05-09.

The capture used a local Docker lab with service lab01, container freeswitch, host networking, and a temporary local capture endpoint outside the repository. The full local docker/ lab is ignored to avoid committing logs and generated FreeSWITCH state; the sanitized capture evidence is tracked in docs/docker-capture-evidence.md. See docs/fixture-provenance.md.

Live smoke

An opt-in live Docker FreeSWITCH smoke harness is available for operators who have the local lab. It is not part of normal CI or composer check.

Chaos smoke

An opt-in Docker FreeSWITCH chaos harness is available for controlled local failure-mode validation. It is not part of normal CI or composer check.
