Session Continuity

When a user abandons a USSD flow and dials back within the configured timeout, the package can resume the previous session.

How It Works

Each state entry persists continuity metadata (state, timestamp, optional payload).
On a fresh dial-in with no input, the machine checks if the previous session is still valid.
If valid, the user receives a prompt asking to resume or restart.
Their selection routes either to the stored state or the initial state.

Configuration

Update config/ussd.php:

'continuity' => [
    'enabled' => true,
    'timeout' => 900,
    'resume_prompt' => 'Pick up where you left off?',
    'resume_option_key' => '1',
    'resume_option_text' => 'Resume previous session',
    'restart_option_key' => '2',
    'restart_option_text' => 'Start over',
],

Custom Prompts

Publish the language files and edit resources/lang/catalysteria/laravel-ussd/en/messages.php to localize resume text.
