1. EAEO siezes outgoing trunk
2. Carrier responds with wink-start
3. After wink, delay of 40 to 200 ms before you outpulse
    If carrier requested ANI, you outpulse KP+II+ANI(10 digits)+ST,  
otherwise you send KP+ST
4. After customer completes dialing, EAEO outpulses KP+(0)+7/10 digits+ST
5. Carrier responds with wink
6. Carrier returns true called party answer supervision.


If you are connecting via an Access Tandem:
1st state dialing:

KP+0ZZ+XXX+ST

0ZZ=spare tandem center code
XXX=dialed or presubscribed CIC

2nd state as above.

I'm not sure how Asterisk handles this but I will tak e a look.

You might request Feature Group C signaling, just to test and see if you  
can make it work.
It is: KP+DNIS+ST
Then if you can "talk" go back to working on the FGD.
