Call Transfer SIPML5+Asterisk

[sil...@bankimia.com]

Hello,

i'm developing (try) a webphone using SIPML5 + Asterisk 13

I have 3 users: A,B and C.  User A B C are registered success on my sip server. User A call B and B answered. User A put on hold B and call C and then C answer. User A click the transfer button on his interface to transfer B to C, The system makes a new call instead of only transfer the call and when B response, hang up A call. I just want it done directly transfer, without making a new call.

Can anyone help me??

Thanks.
