[asterisk-ss7] CIC isn't same of Telco

Just to mention, Alcatel S12 and Neax 61E aren't softswitches, they're good old fashion TDM switches.

If you need to ITX with 4 different switches you will need at least 4 SPC, and you defined just 2 (80 as STP and 100 as SP).

Guessing that S12_01 and NEAX_02 are acting as STP for S12_02 and NEAX_01, and assuming S12_01 is 80, S12_02 is 100, NEAX_01 is 120 and NEAX_02 is 140, it should be something like this:

;s12_01
;because you've cic's with S12_01
linkset=1
pointcode=80
adjpointcode=80

cicbeginswith = 1
networkindicator=national
sigchan = 16
channel = 1-15,17-31

;s12_02
;just cics
linkset=2
pointcode=100
adjpointcode=80				'STP s12_01
defaultdpc=80

cicbeginswith = 1
networkindicator=national
channel = 32-62

;neax_01
;just cics
linkset=3
pointcode=120
adjpointcode=140			'STP neax_02
defaultdpc=140

cicbeginswith = 1
networkindicator=national
channel = 63-93

;neax_02
;because you've cic's with neax_02
linkset=4
pointcode=140
adjpointcode=140

cicbeginswith = 1
networkindicator=national
sigchan = 109
channel = 94-108,110-124


In any case, you can use 1-31 as CIC in that scenario, you just need to get the proper information to define the linksets.

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?
