kstmostofa / laravel-esl
A Laravel package for FreeSWITCH ESL connection.
Requires
- php: >=8.0
- illuminate/support: ^8.0|^9.0|^10.0|^11.0|^12.0
README
A Laravel package for connecting to and interacting with a FreeSWITCH ESL (Event Socket Library) server.
Features
- Easy configuration for FreeSWITCH ESL connection details.
- Fluent API for sending commands to FreeSWITCH.
- Handles connection and authentication automatically.
- Provides a
Esl
facade for convenient access. - Includes a custom exception for robust error handling.
- Automatic resource management (disconnection).
Installation
You can install the package via Composer:
composer require kstmostofa/laravel-esl
The package will automatically register its service provider and facade.
Configuration
To publish the configuration file, run the following command:
php artisan vendor:publish --provider="Kstmostofa\LaravelEsl\LaravelEslServiceProvider"
This will create a config/esl.php
file in your application's config directory. You can then configure your FreeSWITCH ESL connection details in your .env
file:
ESL_HOST=127.0.0.1
ESL_PORT=8021
ESL_PASSWORD=ClueCon
Usage
You can interact with the FreeSWITCH ESL server in two primary ways:
Using the Esl
Facade
The Esl
facade provides a quick and easy way to send commands.
use Kstmostofa\LaravelEsl\Facades\Esl; use Kstmostofa\LaravelEsl\EslConnectionException; try { // Execute the 'status' command $response = Esl::execute('status'); echo "FreeSWITCH Status:\n"; print_r($response); // Originate a call $uuid = Esl::execute('originate user/1000 &echo'); echo "Call UUID: " . $uuid; } catch (EslConnectionException $e) { // Handle connection or authentication errors Log::error('ESL Connection failed: ' . $e->getMessage()); }
Using a Custom Connection
For situations where you need to connect to a different FreeSWITCH server on-the-fly, you can use the connection()
method before executing a command. This will not affect the default connection configuration.
use Kstmostofa\LaravelEsl\Facades\Esl; use Kstmostofa\LaravelEsl\EslConnectionException; try { // Use the default connection from your config $defaultStatus = Esl::execute('status'); // Connect to a different server for a specific command $customStatus = Esl::connection('10.0.1.5', 8021, 'another_password') ->execute('status'); } catch (EslConnectionException $e) { Log::error('ESL command failed: ' . $e->getMessage()); }
Available Command Methods
The package provides the following helper methods for common API commands to make your code more readable.
// Get the server status $status = Esl::status(); // Get a list of all active channels $channels = Esl::showChannels(); // Get a list of all active calls $calls = Esl::showCalls(); // Get the global sofia status $sofiaStatus = Esl::sofiaStatus(); // Get the status of a specific sofia profile $profileStatus = Esl::sofiaStatusProfile('internal');
For any command that does not have a dedicated helper method, you can use the execute()
method directly:
// For example, to get the server uptime $uptime = Esl::execute('uptime');
Using Dependency Injection
You can also type-hint the EslConnection
class in your controllers or other classes to have it automatically injected by Laravel's service container.
use Kstmostofa\LaravelEsl\EslConnection; use Kstmostofa\LaravelEsl\EslConnectionException; use Illuminate\Http\Request; use Illuminate\Support\Facades\Log; class CallController extends Controller { private $esl; public function __construct(EslConnection $esl) { $this->esl = $esl; } public function makeCall(Request $request) { try { $destination = $request->input('destination', 'user/1001'); $uuid = $this->esl->execute("originate sofia/gateway/my_gateway/{$destination} &echo"); return response()->json(['message' => 'Call initiated.', 'uuid' => $uuid]); } catch (EslConnectionException $e) { Log::error('ESL command failed: ' . $e->getMessage()); return response()->json(['error' => 'Failed to initiate call.'], 500); } } }
Response Parsing
Currently, the execute
method returns the raw response body from the FreeSWITCH API command. Future versions will include a more sophisticated parser to return structured data.
