Tomorrow I will create the same config in my lab. Keep you posted.

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?
