Ok ! I figured out what the problema was !
I use the spanish Default IVR. I was also selecting Spanish as the Tone Language.
?WHAT THE HECK IS TONE LANGUAGE? Well, that's what I started asking myself before I realized that each language also has a set of tones (ring tones) asociated with it, correct? So I Spanish does not have one setup, or maybe switching to it has a bug.
If Tone language is indeed the tones asociated with a language pack, I suggest naming that RingTone Set, and not asociating it with a language, unless for some geographic regions there are different tones. If that's the case, then please include the english tone set for spanish also
Thanks guys, I am once again a happy user.
