Gustavo,

I configure the informations like carrier sent to me.
The linkset nothing more than my local identification, ok?

Follow the real configuration?

linkset=1
pointcode=12538
defaultdpc=3979
adjpointcode=3979

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

linkset=2
pointcode=12538
defaultdpc=163
adjpointcode=163

cicbeginswith=1
networkindicator=national
channel=32-62

linkset=3
pointcode=12538
defaultdpc=160
adjpointcode=160

cicbeginswith=1
networkindicator=national
channel=63-93

linkset=4
pointcode=12538
defaultdpc=3980
adjpointcode=3980

cicbeginswith=1
networkindicator=national
sigchan=108
channel=94-107,110-124

The channel 109 has moved because the 16 channel in NEAX is reserverd.

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?
