Hi
Below is the comment that written in
chan_sip.c(handle_request_refer) file of asterisk .In RFC also mentioned
that if blind transfer failed call should connect back, some of phones
support this(If received refer) like cisco,polycom and etc.
\par Blind transfers
The transferor provides the transferee
with the transfer targets contact. The signalling between
transferer or transferee should not be cancelled, so the
call is recoverable if the transfer target can not be reached
by the transferee.
In this case, Asterisk receives a TRANSFER from
the transferor, thus is the transferee. We should
try to set up a call to the contact provided
and if that fails, re-connect the current session.
If the new call is set up, we issue a hangup.
In this scenario, we are following section 5.2
in the SIP CC Transfer draft. (Transfer without
a GRUU)
In asterisk comment is written correct but it is not working.
Thanks
Nikhil

Hi all
In asterisk if blind transfer failed ,call is not connecting
back .
For Eg:
A make call to B through asterisk,then B transfer the call to C.
If C did not answer the call ,A and B Call should connect back.
IMHO, blind tranfer definition is to NOT connect A and B back
That is correct, and is why it's called a 'blind' transfer; the
transferring party does not know or care what happens to the call
after effecting the transfer.
