Erro ao executar método Transfer em JTAPI

Programação Java
#1

Fala galera blz, não estou conseguindo resolver esse problema, já pesquisei em todos os foruns possíveis e nada, alguém já implementou JTAPI aqui?

public void transferX(String target){
		
        Address address = null;
        Call call = null;
        Connection[] connections = null;
        try {
			address = provider.getAddress("3334");
			terminal = provider.getTerminal("3334");
			terminal.addCallObserver(this);
			call = provider.createCall();
			call.addObserver(this);
			connections = call.connect(terminal, address, "3331");
		} catch (InvalidPartyException e) {
			e.printStackTrace();
		} catch (PrivilegeViolationException e) {
			e.printStackTrace();
		} catch (MethodNotSupportedException e) {
			e.printStackTrace();
		} catch (ResourceUnavailableException e) {
			e.printStackTrace();
		} catch (InvalidArgumentException e) {
			e.printStackTrace();
		} catch (InvalidStateException e) {
			e.printStackTrace();
		}
		

        Address address2 = null;
        Call call2 = null;
        Connection[] connections2 = null;
        try {
			address2 = provider.getAddress("3332");
			terminal = provider.getTerminal("3332");
			terminal.addCallObserver(this);
			call2 = provider.createCall();
			call2.addObserver(this);
			connections2 = call2.connect(terminal, address2, "3333");
		} catch (InvalidPartyException e) {
			e.printStackTrace();
		} catch (PrivilegeViolationException e) {
			e.printStackTrace();
		} catch (MethodNotSupportedException e) {
			e.printStackTrace();
		} catch (ResourceUnavailableException e) {
			e.printStackTrace();
		} catch (InvalidArgumentException e) {
			e.printStackTrace();
		} catch (InvalidStateException e) {
			e.printStackTrace();
		}
		
		
		
		
		
		terminalConnection = terminal.getTerminalConnections()[0];
		if(terminalConnection == null) {
	      return;
		}
		
		Connection con1 = call.getConnections()[0];
		Connection con2 = call2.getConnections()[0];
		
        CallControlCall origcall = (CallControlCall)con1.getCall();
        CallControlCall destcall = (CallControlCall)con2.getCall();
		//TerminalConnection tc = (TerminalConnection)destcall.getConnections()[0];
		
		//if(tc == null) {
        if(terminalConnection == null) {
			//System.out.println("tc == null");
        	System.out.println("terminalConnection == null");
		}
		
		
		try {
			origcall.setTransferEnable(true);
			//origcall.setTransferController(tc);
			origcall.setTransferController(terminalConnection);
		} catch(Exception excp) {
			System.err.println("Failed to set transfer controller: " + excp);
			JOptionPane.showMessageDialog(null, "Failed to set transfer controller: " + excp.getMessage(), "Erro", JOptionPane.ERROR_MESSAGE);
		}
		System.out.println("Transfer!!!");
		try {
			origcall.transfer(destcall);
		} catch(Exception excp) {
			System.err.println("Failed to transfer: " + excp);
			excp.printStackTrace();
			try {
				origcall.drop();
			} catch(Exception ex) {
				System.err.println("Exception when droppinng a call: " + ex);
				JOptionPane.showMessageDialog(null, "Exception when droppinng a call: " + ex.getMessage(), "Erro", JOptionPane.ERROR_MESSAGE);
			}
		}
}

E está causando o seguinte erro:
