I've experienced a similar DTMF issue with recent asterisk 1.4 versions (1.4.32, 1.4.33.1), I'm not sure about 1.6.2.X. What happens here is that the DMTF activated features, like disconnect (default *) or blind transfer (default #) stops working after a while. Agents are able to transfer or hangup a few calls and then it stops working. Doing some debugging I could see that asterisk knows (receives) the DMTF too but the features are not triggered... Anyone else has run into this? Regards, -- Ing.
