I'll get to my real pain point - anyone know of a replacement VOIP solution like Hangouts dialer that isn't subscription based? I've been giving my Hangouts number to people forever because its more convenient to have every device I have ring when someone uses the old PSTN but its not worth a recurring bill to me.
