T2xP - Blind Transfer On Hook - What does it do?

Hi team,

I want the ability to transfer an incoming call using the TRAN key like this:

TRAN -> Extension -> Hangup

When I do this, the call stays on hold at the phone. If I do TRAN -> Extension -> TRAN, the call is transfered.

With "Blind Transfer On Hook", I was under the impression that I could just hangup after the extension so the call can be transfered but that does not work ...

So what is the purpose of this option?

I am using version 2.71.0.165 and I am connected to a Freeswitch PBX.

BTW, if I set the phone to do semi-attended transfer and I set the Semi Attend Transfer On Hook, the semi attended transfer kicks in.

Thanks,
Benoit
