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

[Rodrigo Ricardo Passos]

Gustavo,

Thanks for your response.

I make the configuration like you recommend, and the problem persist.
With the first E1, the call is ok, but with the least E1, the call is 
completed, but doesn't have audio.
Other information is, the asterisk cannot create linkset 2 and 3 because 
this linksets doesn't have sigchan and when I place a call using these 
channels, asterisk crash with a segment fault.
I'm with asterisk 1.8.6.0 and libss7 1.0.2.

Regards,

Rodrigo Passos

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?
