Hi, im trying to setup my first SS7 link, i decided to use libss7 and asterisk speclal trunk. I downloaded libss7 and asterisk-ss7 29.12.2006 and succesfully compiled. Im using Tormenta 2 Quad card, with tor2 module. My /etc/zaptel.conf: span=1,1,0,ccs,hdb3 bchan=1-15,17-31 dchan=16 loadzone=pl defaultzone=pl My /etc/asterisk/zapata.conf: [trunkgroups] [channels] language=en context=demo switchtype=national nsf=none pridialplan=national prilocaldialplan=national signalling=ss7 usecallerid=yes hidecallerid=no callwaiting=yes usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes canpark=yes cancallforward=yes callreturn=yes echocancel=yes echocancelwhenbridged=yes rxgain=0.0 txgain=0.0 group=1 callgroup=1 pickupgroup=1 immediate=no signalling = ss7 ss7type = itu linkset = 1 pointcode = 3353 adjpointcode = 14230 defaultdpc = 14230 cicbeginswith = 1 networkindicator=national sigchan = 16 cicbeginswith = 1 channel => 1-15 cicbeginswith=17 channel => 17-31 The link comes up, but i cannot receive call, caller is automaticlly disconnected, i have in demo context s, which should match this number... And from time to time i got HDLC abort - what it can be? - there is output from log: [Jan 2 12:16:55] VERBOSE[12847] logger.c: -- Registered channel 1, SS7 Signalling signalling [Jan 2 12:16:55] DEBUG[12847] chan_zap.c: Failed to read gains: Invalid argument [Jan 2 12:16:55] DEBUG[12847] chan_zap.c: Failed to read gains: Invalid argument [...] [Jan 2 12:16:55] VERBOSE[12847] logger.c: -- Registered channel 30, SS7 Signalling signalling [Jan 2 12:16:55] DEBUG[12847] chan_zap.c: Failed to read gains: Invalid argument [Jan 2 12:16:55] DEBUG[12847] chan_zap.c: Failed to read gains: Invalid argument [Jan 2 12:16:55] DEBUG[12847] chan_zap.c: Updated conferencing on 31, with 0 conference users [Jan 2 12:16:55] VERBOSE[12847] logger.c: Found [Jan 2 12:16:55] VERBOSE[12847] logger.c: == Starting SS7 linkset on span 1 [Jan 2 12:16:55] DEBUG[12847] channel.c: Registered handler for 'Zap' (Zapata Telephony Driver w/PRI) [Jan 2 12:16:56] VERBOSE[12847] logger.c: -- codec_zap: using generic PLC [...] [Jan 2 12:16:57] DEBUG[12871] chan_zap.c: Got GRA from CIC 1 to 15.
