Hi,
here is the proposed follow-up:
We can now terminate calls over SS7 at our asterisk.
The main reason for us to switch to SS7 was the availability to see the
callerid, even if the caller has supressed, so that we can correctly
bill our customers.
But the normal asterisk variable ${CALLERID(number)} will not be filled
if it is suppressed ... Hmmm
Is there another way to check the callerid and the flag wich indicated
that the callerid should not be shown to the callee ?
With ss7 debug enabled here is the output of an incoming call (with
callerid enabled):

Maybe someone can enlighten me with an brief interpretation of the outputs.
Thanks a lot,
