The method getClient() does not exist on Thruway\Peer\RouterInterface. It seems like you code against a sub-type of Thruway\Peer\RouterInterface such as sonrac\WAMP\Routers\Router.

        $callbackAdditional = null;

The assignment to $callbackAdditional is dead and can be removed.

        if ($this->groupControllerNamespace && $this->groupControllerNamespace

The expression $this->groupControllerNamespace of type null|string is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

            && is_string($callback) && count(explode('&', $callback)) === 2) {
            $callback = rtrim($namespace, '\\').$callback;

It seems like $namespace can also be of type string; however, parameter $namespace of sonrac\WAMP\Routers\RouterTrait::parseCallback() does only seem to accept null, maybe add an additional type check?
