Breaking out of handle_response() to handle_response_refer() when the Method == SIP_REFER means all the processing on the response codes will be done in handle_response_refer() for REFER Requests...  There is some generic handling of response codes in handle_response() that is not handled in the handle_response_refer() function.  The only thing that really caught my eye was the 502-504 Server Error codes that queue up a CONGESTION frame on the channel.  That behavior for a REFER response might have been wrong to begin with, or may not even be possible.  I just thought it was worth noting.

I'll look into that.
