x25 connection stays up after the XOT part was going down

We set up XOT via an IP network to reach a public host. The last part of the connection is via an x25 serial connection. that's working fine. There's only 1 "problem" left.

If during the Call the XOT session is lost due to TCP is lost , the Call will be cleared directly (use keepalive 1 second). and the Terminal who initiated the call is cleared. But the X25 session from our last router to the public host stays up and a new Call is not possible till the Host sends a time out.


version 12.2

x25 route 160300300101 interface Serial0 (to the public host)

What can i do to let the XOT session also informs the x25 connection to be cleared as XOT fails?
