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

[Bryan Scott]

Great.  Patch seems to work on the Asterisk side.  But Asterisk (and the switch) complain if the Taqua has anything but SLC 0.  If I use SLC 0 on the T7000 the link comes up, alarms clear, but the CIC's are still unconfigured.

I'm *this* close to using simple PRI circuits.

And Paul, the T7000 is on 6.0.0p20.  I still need to do the isupMsgTrace that you mentioned.  This is on an LTC card.
