Mosbah, Apologies, I didn't READ all of your post. 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" http://www.voip-info.org/wiki/index.php?page=Asterisk+variables Maybe one of the LibSS7 devs will jump in and refer to the right section of the manual.

What Switch (make,model,software) handles Subscriber B? ISUP Switch A will let ISUP Switch B know (if it was configured by people with a notion of the matter) the redirected number plus the ISUP redirection parameters but it is completely unknown in your equation how Switch B and Asterisk relate to eachother. Is Asterisk=Subscriber B or is there any gateway involved which follows any standard (e.g. ISUP<->SIP)? http://www.dialogic.com/webhelp/IMG1010/10.5.1/WebHelp/Description/SIP/sip_d iversion_scen.htm regards, Florian Von: asterisk-ss7-bounces at lists.digium.com [mailto:asterisk-ss7-bounces at lists.digium.com] Im Auftrag von mosbah abdelkader Gesendet: Montag, 22.
