You can configure some services in a better way to help you solve this issue.

If you define your view service like:

    $di->set('view', function () {
        $view = new View();
        $view->setDI($this);
        $view->setViewsDir(__DIR__ . '/views/');

        $view->registerEngines([
            '.volt'  => 'voltShared'
        ]);

        return $view;
    });

You can define your voltShared service improving the volt compiler with custom functions in this way:

$di->setShared('voltShared', function ($view) use ($di) {
    $config = $this->getConfig();

    $volt = new VoltEngine($view, $this);
    $volt->setOptions([
        'autoescape'        => false,
        'compileAlways'     => true,
        'stat'              => true,
        'compiledSeparator' => '_',
        'compiledPath'      => $config->application->cacheDir.'volt/',
    ]);

    // We add some custom functions
    $compiler = $volt->getCompiler();
    $compiler->addFunction('gettext', function ($resolvedArgs) {
        return 'gettext('.$resolvedArgs.')';
    })

    return $volt;
});

I'm guessing you are trying to use a raw PHP function here, so correct me if I'm wrong. Unfortunately I forget the exact reason this is (I learned a long time), but you have to manually register PHP functions in the Volt Engine in order to use them. This can be done using the addFunction method of the Engine will allow you to add them. I thought it had been resolved that this wasn't needed anymore, but it was reported in https://github.com/phalcon/cphalcon/pull/12841.

Anyways, using addFunction: I've used the below to get around this:

foreach (get_defined_functions()['Internal'] as $functionName) {
    $voltEngine->addFunction($functionName, $functionName);
}

You have to put this in the code that initializes the volt engine.

Reading documentation shows that echo command is using {{ }} instead of normal PHP tag <?= ?>:

{% for header in headers %}
<th>
    {{ gettext(header) }}
</th>
{% endfor %}
