Re: Exception in Transfering a call

Use setTransferEnable on the new call that you created using CreateCall.

Call callNew = provider.createCall();
    Connection c[] = ((CallControlCall)
callNew.setTransferEnable(true);

Subject: [JTAPI] Exception in Transfering a call

Hi

I am having problem transfering a call from my JTAPI application.  When
I
try to set callOnTerminal.setTransferEnable(true) , I get the following
exception
com.cisco.jtapi.InvalidStateExceptionImpl: Unable to set transferEnable.
I have checked the pre-condition before invoking this method and find
the
Call in Active state where it should be in IDLE state before I can
invoke
this method.  Here is the code snippet from the callChangedEvent method
-
please let me know where I am going wrong.

//Code
public void callChangedEvent(CallEv[] evlist)
{
for (int i = 0; i < evlist.length; i++)
{
 dbg("CallEv: "+evlist[i]);
 if (evlist[i] instanceof ConnEv)
 {
  ConnEv e=(ConnEv)evlist[i];
  dbg("ConnEv  "+e.getConnection().getAddress());
 }
 else if (evlist[i] instanceof CallEv)
 {
  CallEv e=(CallEv)evlist[i];
  dbg(" CallEv "+e.getCall());
 }
        try
 {
  if (evlist[i] instanceof ConnInProgressEv)
  {
   ConnInProgressEv e=(ConnInProgressEv)evlist[i];
   dbg("callChangedEvent::ConnInProgressEv");
  }
  else if (evlist[i] instanceof CallCtlConnEstablishedEv)
  {
  dbg("callChangedEvent::CallCtlConnEstablishedEv");
   }
   else if (evlist[i] instanceof CiscoTransferEndEv)
   {
    dbg("callChangedEvent::CiscoTransferEndEv");

   }
   else if (evlist[i] instanceof CallInvalidEv)
   {
    dbg("callChangedEvent::ConnInProgressEv");
   }
   else if (evlist[i] instanceof TermConnRingingEv)
   {
    dbg("callChangedEvent::TermConnRingingEv");

    ringingTc = ((TermConnEv)evlist[i]).getTerminalConnection();
    ringingTc.answer();

    dbg("Exiting TermConnRingingEv.ID");

   }
   else if (evlist[i] instanceof TermConnActiveEv)
   {
    dbg("callChangedEvent::TermConnActiveEv");
    talkingTc = ((TermConnEv)evlist[i]).getTerminalConnection();
   }
   else if (evlist[i] instanceof CallCtlTermConnTalkingEv)
   {
    dbg("callChangedEvent::CallCtlTermConnTalkingEv");

    final Address origaddr = provider.getAddress("3596");
    Terminal[] terminals = origaddr.getTerminals();
    final Terminal origterm = terminals[0];

    ((CallControlTerminalConnection) talkingTc).hold();

    callOnTerminal = (CallControlCall)
((TermConnEv)evlist[i]).getCall();

    if (provider.getState()== Provider.IN_SERVICE)
     dbg("Pre-Condition Provider State : Provider.IN_SERVICE" );
    if (callOnTerminal.getState()== Call.IDLE)
     dbg("Pre-Condition Call State : Call.IDLE" );
    if (callOnTerminal.getState()== Call.ACTIVE)
     dbg("Pre-Condition Call State : Call.ACTIVE" );
    if (callOnTerminal.getState()== Call.INVALID)
     dbg("Pre-Condition Call State : Call.INVALID" );

    callOnTerminal.setTransferEnable(true);
    callOnTerminal.setTransferController(talkingTc);

    Call callNew = provider.createCall();
    Connection c[] = ((CallControlCall)
callNew).connect(origterm,origaddr,sDialedDigit);

    if (provider.getState()== Provider.IN_SERVICE)
     dbg("Pre-Condition Provider State : Provider.IN_SERVICE" );
    if (callNew.getState()== Call.IDLE)
     dbg("Pre-Condition callNew State : Call.IDLE" );
    if (callNew.getState()== Call.ACTIVE)
     dbg("Pre-Condition callNew State : Call.ACTIVE" );
    if (callNew.getState()== Call.INVALID)
     dbg("Pre-Condition callNew State : Call.INVALID" );

    try
    {
     ((CallControlCall) callNew).transfer(callOnTerminal);
    }
    catch(Exception e)
    {
     dbg("Exception");
    }

   }
  }
  catch (Exception e)
  {
   println("ERR: Exception (7) "+e); }
 }
