TromboneDisconnectCall is not valid at this time
A TromboneDisconnectCall request has been made to IBM_Trombone_Custom_Server at an invalid time (out of sequence). This might happen if the default state tables have been customized and the order of the operations needed to complete a trombone is now incorrect.
Check that the state tables implementing the trombone are doing this correctly (the default state tables should be used as a guide to correct operation).
If the problem persists, re-create the problem and take an AIX system trace (specify the -d command-line parameter for the custom server), before calling Blueworx Support. Also be prepared to give details of any customization that has been made to the default trombone state tables.
