pass lambda to function that accepts function with templated types

I'm attempting to make a template function that takes a function as a parameter and the parameter function has arguments for the template to deduce.

Example time:

Here is a function that accepts a fixed function type and works

void func_a(void(*func)(int)) {
    func(1);
}
int main() {
    auto f = [](int x) -> void { printf("%i\n", x); };
    func_a(f);
    return 0;
}

Here is what I want to do, expanding on the first example (this won't compile)

template <typename... T>
void func_b(void(*func)(T...)) {
    func(1);
}
int main() {
    auto f = [](int x) -> void { printf("%i\n", x); };
    func_b(f);       // neither of
    func_b<int>(f); // these work
    return 0;
}

Ideally I'd like func_b to accept both a regular function and a lambda function like func_a does, but with template magics.
