This is just because we don't like to make our live miserable. Think about someone sending RFC2833 (=RFC4833) DTMF tones and then while the tone is playing back someone sends a INFO as well. Plus the support for RFC2833 tones is pretty good these days. Quote Link to comment Share on other sites More sharing options...
