[asterisk-users] question about call transfer

[Rilawich Ango]

Hi all,
 Refer to http://www.voip-info.org/wiki/view/Asterisk+config+features.conf.
 It shows we can use variable BLINDTRANSFER to call back the one who
transfer the call.  However, in my tests below.  The result is not as
expected.

case 1:
A calls B (dial(sip/B||Tt)
B answers and connects to A
B transfer to C
C doesn't answer the call and B ring again

case 2:
A calls B (dial(sip/B||Tt)
B answers and connects to A
A transfer to C
C doesn't answer the call but B ring instead of A

In case 2, the person who transfer the call can't get back the call.
Anyone can tell whether there is a way to correct in case 2?
Thanks, ango
