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
