[asterisk-ss7] Can not get ss7 link working on Siemens switch!!

[research at businesstz.com]

Dear List

I have configured the ss7 and connect to GSM switch using ISUP. They can
not see me but the physical link is tested to be ok

MSC is Siemens and they are asking if i have set the slc. I then put slc=0
but still is not working

Here is the ss7linktest result

[root at INVPBX01 ~]# /usr/src/asterisk-trunk/libss7-trunk/ss7linktest 16 itu
139 1152
Starting link 1
Link state change: IDLE -> NOTALIGNED
Len = 4 [ ff ff 01 00 ]

BSN: 127 BIB 1

Here is my system.conf
