    I want to implement an extension to t38modem code, so that we can get the exact connection time of the last call from OPAL library and/or the exact disconnect cause / reason (Q.850). To get the values we can implement 2 AT commands, which are not used until now: ATT (for connection time) and ATC (for disconnect cause).

    The AT command protocol does not allow to determine the exact connection time because the exact time of connect is not estimable. So we have to get this value from lower layers: is it possible to get this from difference of methods GetConnectionEndTime() and GetSetupUpTime()???

    If I unterstand it correctly OpalConnection does not exist long enough to get these values, how would you do this???

    Best Regards,
