Hi all, I have the following scenario: The telco company uses 4 different Softswitchs to compose my SS7 interconnection, so 4 E1s to have redundancy. Each this one uses channels 1 up to 31. The map of the firsts is equal the ID of the asterisk channels, but the next ID?s isn't the same and the signaling doesn't work. The telco cannot change the CIC configuration to have the same CIC in my configuration. I have one TE405P. The only way to solve this problem is change the CIC in the telco company or i can change CIC maps in my asterisk box? Only the first E1 align with the first softswitch. When I a place a call using channel 64 of my third E1, telco doesn't have CIC 64, but have CIC 2 and the cannot be complete because the CIC isn't the same. What is the solution? First E1: Asterisk: 1 - 31 (16 signaling) - Alcatel: S12_01 1-31 (16 signaling) Second E1 Asterisk: 32 - 62 (no signaling - voice only) - Alcatel: S12_02 1 - 31 Third E1: Asterisk: 63 - 93 (no signaling - voice only) - NEC: NEAX_01 1 - 31 Fourth E1: Asterisk: 94 - 124 (16 signaling) - NEC: NEAX_02 1 - 31 All dpcs are different; each this one have an unique ID for each E1, only problem is the signaling. My configurations are: system.conf: span=1,1,0,ccs,hdb3 # termtype: unknown bchan=1-15,17-31 mtp2=16 # Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" HDB3/CCS span=2,1,0,ccs,hdb3 # termtype: unknown bchan=32-62 # Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3" HDB3/CCS span=3,1,0,ccs,hdb3 # termtype: unknown bchan=63-93 # Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" HDB3/CCS span=4,1,0,ccs,hdb3 # termtype: unknown bchan=94-107,110-124 mtp2=108 # Global data loadzone = us defaultzone = us chan_dahdi.conf: [trunkgroups] [channels] context=interconexoes ss7type=itu signalling=ss7 ss7_called_nai=dynamic ss7_calling_nai=dynamic networkindicator=national echotraining=yes echotraining=800 echocancel=yes group=1 linkset=1 pointcode=100 defaultdpc=80 adjpointcode=80 cicbeginswith=1 channel=1-15 cicbeginswith=17 channel=17-31 sigchan=16 cicbeginswith=32 channel=32-62 pointcode=100 defaultdpc=90 adjpointcode=90 cicbeginswith=63 channel=63-93 cicbeginswith=94 channel=94-107 cicbeginswith=110 channel=110-124 sigchan=108
