the sls in mtp3 message the number of the adjacent SP
in isup message come from cic

it is fixed in my svn:
svn co https://observer.router.hu/repos_pub/libss7/trunk libss7
svn co https://observer.router.hu/repos_pub/chan_dahdi/trunk chan_dahdi

chan_dahdi.c is tested in asterisk-1.6.0.9

I don't know ANSI but I think SLS is not the param in the LUN message it
is the part of the routing label.
If not works I will google the ansi standard and I will fix it if you
can test it.
