Summary:                    response_refer() does not have a default case, so a
400 final response stalls in the Transfer() application
Description: 
For an outgoing refer request, generated by the Transfer() application,
chan_sip.c's response_refer routine only recognizes specific response
codes, which don't include "400 Bad Request", the generic 400 response
code.

As a result, if it gets an unrecognized final status, it does not wake up
the Transfer application to allow it to return a FAILURE response to the
dialplan.  

Cisco CCM 6 can generate this response to REFER, although not necessarily
to the REFERs generated by the standard Asterisk code.
