I believe the control stack handling media (which could well be chan_dahdi) does send received media along to any other involved channel constantly and the receiver chan_sip just discards it (while busy sending media from internal tone generator = fake ringing, treatment tone or comfort noise) unless early media capability is explicitly requested instead of those alternatives, latest when the B-channel enters a connected state when the signaling stack updates the channel variable to twoway audio after receiving the SS7 ANM message from the far end. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Kind regards, Florian<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-left:solid blue 1.5pt;padding:0cm 0cm 0cm 4.0pt'><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Von:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> asterisk-ss7-bounces@lists.digium.com [mailto:asterisk-ss7-bounces@lists.digium.com] <b>Im Auftrag von </b>Nyamul H</span><span lang=DE style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>assan<br><b>Gesendet:</b> Mittwoch, 22.
