Bill, The question has been answered; Asterisk is NOT capable of providing a clear PTP TDM path between two boxes configured with t1 cards and any type of trunking.
I am aware of my other options, and will move forward with the knowledge that a solution we have implemented with back to back Cisco routers in the past is not possible with asterisk. I do intend to move forward with asterisk in this particular environment, but I wish to integrate asterisk by placing it between the telco PRI and the primary Nortel switch, not between the primary switch and a branch office on a T1 tie trunk. I will leave the leased PTP t1 in place for now since it cannot be dropped without significant additional work for a temporary situation. BTW, I did learn that the RAD IPMux-11 will do exactly what we need, but cost is about $1500/pair, so the break even on a $300/mo leased line is 5 months, in which time we are not planning to need the T1 anymore. With that said, it is still about $6k less than the Cisco solution.
