Summary:                    external lines connected with message !! Got Busy in
Connected State !?!
Description: 
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 back again by putting the
call "off hold"

And then the external line is disconnected.
an exact log of events is recorded and is given in the additional
information

This happens a few times a day, i am not sure if this is the right place
to post this error, but it troubles me for a lang while. I first thought
the telephone was the cause of this problem (linksys 962). I've chosen the
Digium Wildcard B410P ISDN BRI as my ISDN interface, the reason was that i
thought it would seamless integrate into asterisk (digium digium) therefor
i hope that this answer is also answered in this asterisk thread.

in the asterisk user section some-one else also has this issue
