I give you just and example, did you get all the information from the carrier about the SPCs?

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?
