Hello All, i m having problem on CIC mapping. i already tried as Barry describe before I have attached the telco CIC mapping. My telco ( Ericsson switch) is giving me my SS7 signal on channel 1. here is my zaptel.conf and zapata.conf file. i m using asterisk-trunk(122043), libss7-trunk(176), zaptel-branches(4351), libpri-trunk(570). using one Digium 407P and another sever with one Sangoma A108d on Quad Core Xeon server. TELCO CIC Mapping E1 Timeslot CIC Value 0 Synchronisation 1 1 Signal 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 12 12 13 13 14 14 15 15 16 16 Empty/Delta 17 17 18 18 19 19 20 20 21 21 22 22 23 23 24 24 25 25 26 26 27 27 28 28 29 29 30 30 31 31 zaptel.conf # Zaptel Channels Configurations (zaptel.conf) # loadzone=us defaultzone=us span=1,0,0,ccs,hdb3 bchan=2-15,17-31 dchan=1 span=2,0,0,ccs,hdb3 bchan=32-62 zapata.conf signalling=ss7 ss7type = itu linkset = 1 pointcode = 4521 adjpointcode = 9321 defaultdpc = 9321 sigchan = 1 cicbeginswith=2 channel = 2-15,17-31,32-46,48-62 using that configuration i having CIC-16 on zap/17, calls r ok, but after 3 to 4 hour the asterisk server goes down. and i saw that kinda msg on the asterisk log many time " chan_zap.c: REL on channel (CIC 26) without owner!" & "chan_zap.c: Received RLC out and we haven't sent REL. Ignoring." . if i use cicbeginswith=1 then zap/17 have the CIC-17. But the problem is that when put this no call is passing out from the system. Can u pls guide me if i had done anything wrong Best Regards shaon -------------- next part -------------- An HTML attachment was scrubbed...
