[asterisk-users] message: !! Got Busy in Connected State !?!

[Fons van der Beek]

Hello all,
 I am using asterisk 1.4.17 together with misdn,  once in a while:

-when a call was put on hold
-the operator tries to call a internal party for transfering the call
-the internal party doesn't answer the phone
-the operator wants to get the external line backup again by putting the 
call "off hold"
And then the external line is disconnected.

an exact log of events is recorded and is given below:
Can somebody give me a clue how to solve this issue   ??????
