I have some issues this attended transfer.
We have incoming call. Agent answer it and try to transfer call to another extension using asterisk attended transfer feature code. Extension successfully answered. After talk, extension was hangup the call. Now call return to agent. But no beep after return. This is a problem.
atxfernoanswertimeout = 10
atxferloopdelay = 1
xfersound = beep
xferfailsound = beeperr
pickupsound = beep
pickupfailsound = beeper
What else can i do to resolve this problem?
