After the outbound flow is started, a 12-second delay occurs.

Events are always occurring every time.

Looking at the trace log, there is a delay in the following part.

We are requesting AVAYA support separately for AEP based survey.

Inbound flow deployed to the same application server is working without problems.

If this problem is not solved the project will fail.

The lines (below) from the OD trace.log indicates that there is a delay of more 8 second between the Start and dAC0010A. But you have to look into the AVB log on EP to find out why there is a delay calling dAC0010A.
