Hi The update is that chan_ss7 worked flawlessly on my link with mostly default settings. So that means the link is not making error. Perhaps there is a bug in libss7 or some config problem. I will update. Thanks for looking at this. Here is my working chan_ss7 1.4.3, wanpipe 3.5.18 and asterisk 1.6.2 config files that work with Sangoma A108 card. # cat /etc/asterisk/ss7.conf [linkset-siuc] enabled => yes enable_st => no use_connect => yes hunting_policy => even_mru context => ss7 language => da t35 => 15000,timeout subservice => auto [link-l1] linkset => siuc channels => 1-15,17-31 schannel => 16 ; The first CIC firstcic => 1 enabled => yes echocancel => no echocan_train => 350 echocan_taps => 128 [host-debian] ; The host is enabled enabled => yes opc => XXXXX dpc => siuc:XXXX ; Syntax: links => link-name:digium-connector-no ; The links on the host is 'l1', connected to span/connector #1 links => l1:1 [devices] wanpipe1 = WAN_AFT_TE1, Comment [interfaces] w1g1 = wanpipe1, , TDM_VOICE, Comment # cat /etc/wanpipe/wanpipe1.conf [wanpipe1] CARD_TYPE = AFT S514CPU = A CommPort = PRI AUTO_PCISLOT = NO PCISLOT = 4 PCIBUS = 5 FE_MEDIA = E1 FE_LCODE = HDB3 FE_FRAME = NCRC4 FE_LINE = 1 TE_CLOCK = NORMAL TE_REF_CLOCK = 0 TE_SIG_MODE = CCS TE_HIGHIMPEDANCE = NO TE_RX_SLEVEL = 430 LBO = 120OH FE_TXTRISTATE = NO MTU = 1500 UDPPORT = 9000 TTL = 255 IGNORE_FRONT_END = NO TDMV_SPAN = 1 TDMV_DCHAN = 0 TE_AIS_MAINTENANCE = NO TDMV_HW_DTMF = NO TDMV_HW_FAX_DETECT = NO HWEC_OPERATION_MODE = OCT_NORMAL HWEC_DTMF_REMOVAL = NO HWEC_NOISE_REDUCTION = NO HWEC_ACUSTIC_ECHO = NO HWEC_NLP_DISABLE = NO HWEC_TX_AUTO_GAIN = 0 HWEC_RX_AUTO_GAIN = 0 HWEC_TX_GAIN = 0 HWEC_RX_GAIN = 0 [w1g1] ACTIVE_CH = ALL TDMV_HWEC = NO MTU = 8 It may be noted that wanpipe1.conf for libss7 and chan_ss7 is the same with both having TDMV_DCHAN = 0 # cat /etc/dahdi/system.conf loadzone=us defaultzone=us #Sangoma A108 port 1 [slot:4 bus:5 span:1] <wanpipe1> span=1,1,0,ccs,hdb3 bchan=1-31 echocanceller=mg2,1-15,17-31 Note that in dahdi/system.conf all channels are defined as bearer channels. chan_ss7 deals with the "D Channel" or signchan in its internal space as defined in ss7.conf -------------- next part -------------- An HTML attachment was scrubbed...
