Hi,
I am trying to learn Attended Transfer.
I have 3 extension 6001,6002,6003.
When 6001 got call from 6002. After accepting it, 6001 decide to use Attended transfer to 6003.
So he dial *26003, then call connect to 6003. Now 6002 & 6003 can talk each other.
But 6001 who initiate attended transfer got music in call.
When 6003 disconnect call then again 6001 resume on call & can hear 6001’s words.

Is this happening is right or I do some thing mistake so I got this results.
For ref following dialplan & features I used.
In features.conf
parkext => 700
parkpos => 701-750
context => parkedcalls

blindxfer => #1
atxfer => *2
parkcall => #72

In extensions.conf

exten => _6XXX,1,Answer()
exten => _6XXX,n,Dial(SIP/${EXTEN},,Tt)
exten => _6XXX,n,Hangup()

Need help.
Thanks.

The console output would also be needed like I mentioned.

Hi,
Sorry for delayed reply.
I put verbose, debug on 99, active almost all debug & then collect the log.

  1. 6001 to 6003 call
  2. Then 6001 attended Transfer to 6002
  3. So 6001 listen music.
    I found as below:-
    Debug log:-
    DEBUG[17056][C-00000000] bridge_basic.c: Attended transfer to '6002@spy’

Hope this log explain whether I am doing anything wrong or not at time of attended transfer.
Thanks,
