[asterisk-r2] Invalid Multi Frequency Tone

[Vinícius Fontes]

Changed the variant to ITU, now the phone I dialed rings once and the call is dropped. Here's the call trace: http://pastebin.com/jCr4hSsb

I liked the idea of using a different variant, altought the problem is intermittent and doesn't happen always. I noticed it happens a lot more on incoming calls. Do you suggest any other variant worth testing?
