[asterisk-ss7] SS7 : Missing SLC parameter on ANSI ??

[Ruddy Gbaguidi]

Even ANSI is selling them 300$ each.
Seems to be an expensive investment to just know how the protocol is suppose to be and try to fix it.
Nobody has it for free ??

ANSI specs for SS7 are available from ANSI :)
Or, you can buy them from Telcordia, they have a document set for SS7 &
ISUP.  I think its around $4000.
