It would appear that the switch doesn't like what you're sending it. 
That means either your switch at the other end is not configured with 
this feature enabled or that your switchtype is set incorrectly for the 
actual switch type that the other end is expecting.

 From the message you are sending to the other side, it would appear 
that you are configured for either 5ESS or national switch type.

Another possiblity (although low in probability) is that it doesn't like 
being sent the transfer message so soon, since it would appear that we 
have not yet received the CONNECT-ACK from the other switch by the time 
we send the transfer request.

You could try inserting a Wait(5) after you Answer() the call in your 
dialplan before Dial()'ing back out to verify that the call is 
completely setup.  Make sure you try explicitly Answer()'ing the call 
first in your dialplan before Wait()'ing or Dial()'ing back out, at 
least until you figure out what the problem is.
