For problem 1. that is almost certainly because you have ambiguous outbound routes that start with 0, then you will need to wait for "digit timeout" (5 by default) or the "dial terminator" (#)
The TDMOE driver is not well supported by the FreePBX DAHDI helper module, so for problem 2. you will have to manually check that Echo-cancellation, clock source , timing, framing and codec are appropriately agreed on both ends of the link. Particularly the clock source, which probably should be the FreePBX box.
