[asterisk-ss7] Asterisk, Taqua T7000, and you guessed it, SS7

[Bryan Scott]

I've moved the f-link to the last channel (48), but otherwise yes, it
looks like my other SS7 links and trunk groups.  When I query the
circuit range, I get a message on Asterisk saying something about a
message on non-equipped CICs (CQM I think).  I'll get more details in
a little bit (on the iPad now, not at my laptop).

When I run ss7 unblock cic x xx I don't see any debug messages that
would indicate Asterisk is sending anything.  Are you on 1.6?
