AHA, big clue there! Does this work 100% every time, and the o's problem is also 100% reproducible when only power-cycling ? .....if memory serves me correctly, the P400 will do a T1 loop-back towards the CO when power-cycled. When it recovers, and "cut's through" again, it starts to look for the D-channel to be re-started (various different terms used here dependent on the switch), and puts the channels in the "o" state, waiting for that initialization... The network in the meantime *never* saw the PRI go down because of the power-cycle loop-back, so continues to process calls as if nothing had happened. So, since the CO *never* sends the "restart" to the P400, the channels stay in the "o" state....our software however figures that if a call is presented, we should still answer it - the network must know best ;)...and those channels will go back "in service" as a result. The rest still stay in the "o" state waiting for that "restart", or a "wake-up" call... Does this appear to match what we are seeing here ?
