asterisk users - Apr 2005 - blind transfer question

Hello,

When performing a blind transfer to another extension
i.e.

originating extension = 103
transfer extension = 101

# 101

as soon as the extension rings, the handset initiating
(103) the transfer gives a busy tone (or congestion) once
the transfer extension rings

asterisk returns:

SIP/101-71ec is ringing
Got SIP response 486 "Busy" back from 192.168.1.2
SIP/103-7394 is busy


question -
Is there some way to force the originating handset
to go silent then hang up?

wiki has not yielded anything for me neither has google

Regards

Hi all, I'm trying to change the keys associated with the blind transfer 
function.  I've been mucking around in features.conf, but nothing I do 
seems to make any difference ( and I've tried to intentionally break it 
).  I have restarted the * server between each modification.

Is this a known thing?  Can anybody give me an idea of how to change the 
Blind Transfer key sequence to something else?
