So I am to change my answer as follows: Switch A becomes rather irrelevant here, except for the point of certifying you the calling party number to be network provided and verified (else, you don’t trust calls CLI for voicemail authentication and reverse charged services). Switch B must be configured right to send the redirection parameters to the ISUP powered Asterisk PBX. Let’s say it will. Now I am not in a position to KNOW the code of LibSS7 to tell you what ISUP information element is stored in which channel variable. I suggest you to dump ALL possible ones with a NoOp function in your incoming context. You can find the variables here under the paragraph “Predefined Channel Variables”<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'><a href="http://www.voip-info.org/wiki/index.php?page=Asterisk+variables">http://www.voip-info.org/wiki/index.php?page=Asterisk+variables</a><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'>Maybe one of the LibSS7 devs will jump in and refer to the right section of the manual.<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'>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><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><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Von:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> florian@gruendler.net [mailto:florian@gruendler.net] <br><b>Gesendet:</b> Montag, 22.
