So should a PeerConnection object establish a separate audio channel when created specifically for sending RFC 4733 DTMF event codes to legacy phone networks, with a corresponding API? Or can event codes be sent over the same audio channel as any other audio stream? I didn't follow the RFC enough to answer that question. Also, how long and how loud should the events be? Should all event codes be supported, or only 0-9, *, and #, or those as well as A-D? -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
