hi i have problems with chan_ss7 to work with EWSD . i have tried many configuration with and without crc4, with different clock sources without success, i always get NOT_ALIGNED message i have also tried ss7 dump, but there wasn't any output many thanks for any help, and sorry for my english ;) ############status dmesg ADDRCONF(NETDEV_CHANGE): w1g1: link becomes ready wanpipe1: Global TDM Ring Resync wanpipe1: Card TDM Rsync Rx=0 Tx=2 wanpipe1: RAI alarm is OFF wanpipe1: OOF alarm is OFF mtrr: type mismatch for f9000000,800000 old: write-back new: write-combining voicegw*CLI> ss7 link status linkset siuc, link l1, schannel 1, sls 0, NOT_ALIGNED, rx: 0, tx: 4/4, sentseq/lastack: 127/127, total 4754816, 4754912v i am also getting this message WARNING[4390]: mtp.c:513 t2_timeout: MTP2 timer T2 timeout (failed to receive 'O', 'N', or 'E' after sending 'O'), initial alignment failed on link 'l1'. here are my configs #dahdi system.conf #autogenerated by /usr/sbin/wancfg_dahdi do not hand edit #autogenrated on 2009-06-03 #Dahdi Channels Configurations #For detailed Dahdi options, view /etc/dahdi/system.conf.bak loadzone=us defaultzone=us #Sangoma A108 port 1 [slot:4 bus:3 span:1] <wanpipe1> span=1,1,0,ccs,hdb3,crc4 #span=1,0,0,ccs,hdb3 bchan=1-31 wanpipe1.conf #================================================ # WANPIPE1 Configuration File #================================================ # # Date: Wed Dec 6 20:29:03 UTC 2006 # # Note: This file was generated automatically # by /usr/local/sbin/setup-sangoma program. # # If you want to edit this file, it is # recommended that you use wancfg program # to do so. #================================================ # Sangoma Technologies Inc. #================================================ [devices] wanpipe1 = WAN_AFT_TE1, Comment [interfaces] w1g1 = wanpipe1, , TDM_VOICE, Comment [wanpipe1] CARD_TYPE = AFT S514CPU = A CommPort = PRI AUTO_PCISLOT = NO PCISLOT = 4 PCIBUS = 3 FE_MEDIA = E1 FE_LCODE = HDB3 FE_FRAME = CRC4 FE_LINE = 1 TE_CLOCK = NORMAL TE_REF_CLOCK = 0 TE_SIG_MODE = CCS TE_HIGHIMPEDANCE = NO LBO = 120OH FE_TXTRISTATE = NO MTU = 1500 UDPPORT = 9000 TTL = 255 IGNORE_FRONT_END = NO TDMV_SPAN = 1 TDMV_DCHAN = 16 TDMV_HW_DTMF = YES TDMV_HW_FAX_DETECT = NO [w1g1] ACTIVE_CH = ALL TDMV_HWEC = YES ss7.conf [linkset-siuc] ; The linkset is enabled enabled => yes ; The end-of-pulsing (ST) is not used to determine when incoming address is complete enable_st => no ; Reply incoming call with CON rather than ACM and ANM use_connect => yes ; The CIC hunting policy (even_mru, odd_lru, seq_lth, seq_htl) is even CIC numbers, most recently used hunting_policy => even_mru ; Incoming calls are placed in the ss7 context in the asterisk dialplan context => ss7 ; The language for this context is da language => da ; The value and action for t35.
