I have an issue with the detection of the DTMF tones. When I try with audio archives through my computer, I have no problem, but when I connect my phone, nothing is detected. I don´t know why.

What I have in mind is to connect one phone to my arduino board, with voicemail active, then if there is an incoming call, the voice mail pick up the call and because of this is allowed to dial the tones. For example 001 wich turns on the heating.

But without detection through my mobile I am blocked, what can I do?

Thanks for your help in advanced
