GOautodial Open Source Omni-channel Contact Center Suite

Hello,

I have installed Goautodial 3.3 version with the last update in a VM (ESXi 5.5) and everything is working good, but when I try to make a Transfer to an agent, it doesn´t work.
What happens is:

1. Agent 8015 make a call to a number (8002474747)
2. When the customer answer the phone, Agent 8015 try to make a Warm transfer to the Agent 8001 (I use the consultative checked box)
3. Press the "Dial with the customer" button and the call hung up.
It shows this in the CLI:

I use this follow dial plan reconfigured in the carrier:
exten => _91NXXNXXXXXX,1,AGI
exten => _91NXXNXXXXXX,n,SET=xxxxxxxxx)
exten => _91NXXNXXXXXX,n,Dial(${SIPtrunk}/${EXTEN:1},30,To)
exten => _91NXXNXXXXXX,n,Hangup

I still can do the transfer with the button "Local Closer", using the Direct Agent In group, but this option doesn´t let me talk to the agent first.

I have check for a week everywhere and I can´t find something related with this error.

I need help on this...

Thanks,
