I'm still playing catch up on SS7 so bear with me if I stumble on stuff.

I know the AS5400 has STP functionality and I can terminate A-links 
from the Verizon STP.   What would handle the ISUP messages?  Can 
Asterisk handle that part of the transaction?

  I'm a CLEC so I'm planning on getting NPA-NXX thousand blocks from 8 
rate centers in the LATA.  I'll need to handle IMT trunks from the 
Verizon access tandem and some Verizon end-offices.  For the amount of 
traffic I'm going to be looking at the SIP-7 stuff would probably be 
cheaper than direct SS7 links.

 From my understanding the originating switch will send an ISUP message 
to my SSP using my point-code over the SS7 network.  The AS5400 would 
get the ISUP message and needs to send it somewhere to figure out what 
to do.  The AS5400 would use MGCP (I think) to talk to a softswitch 
(Asterisk??).  If Asterisk can do it all that would be amazing!

Having Verizon handle my SS7 also frees me from building SS7 A-links in 
every LATA as I need to expand.
