Dear Kristian It helped me too much, now i'm realy sure that my chan_ss7 doesn't send ACM after an IAM. It just sending directly CPG Alerting. This behaviour isn't in ITU standarts and therefore the incumbend telecom operator here in Switzerland rejects there calls and sends inmediatelly an REL. chan_ss7 answers to that with an RLC as also expected. So I have to find out now, under which conditions chan_ss7 wants to send an ACM etc...... Thanks again a lot BR Ercan -----Original Message----- From: asterisk-ss7-bounces@xxxxxxxxxxxxxxxx [mailto:asterisk-ss7-bounces@xxxxxxxxxxxxxxxx] On Behalf Of Kristian Nielsen Sent: Donnerstag, 22.
