Hi, I have 5 E1's connected to my asterisk box. These are connected to 2 STP's (pointcodes 1 and 2) through a MGW. Behind the STP's there's an MSC (pointcode 3). Our box is assigned pointcode 4. The first channel of the first 4 E1's are signalling channels. The first 2 E1's are set towards STP1, the 2 following towards STP2. The fifth one is not clear to me where it is going (Does it matter? There;s only CIC's on this E1) How would I go about configuring chan_dahdi.conf? I'm using the patched asterisk 11.5.0 with the patched libss7 as described in https://issues.asterisk.org/jira/browse/SS7-27?focusedCommentId=208465&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-208465 Here's what I currently have: [channels] switchtype=EuroISDN context=incoming group=1 ss7type=itu signalling=ss7 networkindicator=national linkset=1 pointcode=4 adjpointcode=1 defaultdpc=3 sigchan=1 sigchan=32 ss7type=itu networkindicator=national linkset=2 pointcode=4 adjpointcode=2 defaultdpc=3 sigchan=63 sigchan=94 ss7_called_nai=national ss7_calling_nai=national ss7_internationalprefix= ss7_nationalprefix= ss7_subscriberprefix= ss7_unknownprefix= echocancel=yes echocancelwhenbridged=no echotraining=no pridialplan=unknown prilocaldialplan=unknown cicbeginswith=34 channel=2-31 cicbeginswith=66 channel=33-62 cicbeginswith=98 channel=64-93 cicbeginswith=130 channel=95-124 cicbeginswith=161 channel=125-155 For some incoming IAM's I see this in the logs: [Aug 13 09:07:31] VERBOSE[31407] sig_ss7.c: [Aug 13 09:07:31] Linkset 0: Processing event: ISUP_EVENT_IAM Linkset 0! It seems like asterisk can not detect the linkset on which theis message entered. Any thoughts and/or recommendations? Thanks, Frederic
