Problem with disconnecting a connection from a conference call

Hi

I am working on scenarion described below

1. Terminal T1 is the terminal the application is managing which is
forwarded to a Route >point RP and then to a CTI PORT C1 (using slectRoute
in the application).
2. When ConnInProgressEv is received for this CTI Port, accept the connection.
3. When TermConnRingingEv is received - answer the call on C1 and get the
talking terminal connection.
4. When CallCtlTermConnTalkingEv is received make a Call to A using C1. Get
the Call on C1 (callOnterminal) and Conference them.  Make a second Call to
B and conference in with Callonterminal.
5. I receive active call when the application receive the
CiscoConferenceEndEv event by calling getFinalCall().
6. I get four connections back from this call
 conn1 - with originator number
 conn2 - for C1 (CTI Port)
 conn3 - for party A and
 conn4 - for party B
7. If Party A picks up the phone then I just want to execute the following
to drop the unwanted connetion.
 Conn2.disconnect and conn4.disconnect to complete this.


Now get this - Below are four different connections I have in the conference
call.  I get state information for all the connections and also checked
canDisconnect capability on the connection and then I tried to drop one of
the connection with name B which is a internal number. I got "Address is out
of service".

dbg: cs.length 4

dbg: Connection is in Connection.CONNECTED state

B is a valid address and the phone is ringing.  I have no idea what can be
wrong with this. Can anyone help?

Thanks.
