Re: JTAPI 1.2 / XTAPI DTMF Tone detection

Hi All, 
I am having a problem with the creating a PhoneTerminal.
 I have coded as follows:
  Terminal terminal = myprovider.getTerminal("352");
  ComponentGroup groups[] = null;

if (terminal instanceof PhoneTerminal) {
groups = ((PhoneTerminal)terminal).getComponentGroups(); 
..............
 ..............
 }
 but the if statement is always returning false; hence the code will not 
reach the statement within the if scope.
 Thanks and please advise.
