That would be because there is no call termination signal from the PBX. FXO is not
usually a good interface type to use for a PBX interface. The PBX not sending a
disconnect signal is just one of several reasons.

Thank you for your feedback.
The other possible explanation is that the router does not correctly
interpret call termination signal coming from the PBX?
I have to physically unplug the cable from the FXO module to release the
line.

But even if its not recongnizing the call terminal signal coming from
the PBX, that doesn't explain why the line is down after 4 - 5
minutes. Do you also have a timeout ?

-No
-I have tried to extrapolate the accurate down time and it is about 3
minutes.
Actually, the problem is that after the caller terminates the call, the
router does not hook-up immmediately but only after 3 minutes, during which
the line is in busy status.
