Hi,

Try to replace signalling's value on span 4 by bri_cpe.

i have tried to use signalling = bri_cpe on span 4, but in this way i have no signal in. on CLI i have no information about incomming call.

Hi,

Enable the debug parameter in file /etc/asterisk/logger.conf, starting asterisk by `asterisk -vvgc -d`. Increase the verbose value by `core set verbose 10000`. Meanwhile enable the debug by ` core set debug on span X` on the console. And see what happens.
