[Asterisk-Users] SIP-T Support (I got my head in an SS7 cloud)

[brett-asterisk at worldcall.net]

But I would like asterisk to accept the IMTs.. and the only way to do 
that is to find out what DS0 to take and place the calls on based on the 
SS7 messages. I guess one of the things I'm not clear on is going from 
SS7 to SIP-T, I'm not sure where the state machine exists..
