Allow internal transfer when agent is in not ready state.

[PFCCWA]

Hello,
Has anyone managed to allow internal transfer calls (instant or consult) when receiving agent is in not ready state?
in our case, receiving agent has agreed to the transfer, agent1 with call performs transfer but call does not route.
if receiving agent2 changes state to ready they receive call.
there are reasons this wont always work ie if we have queuing calls, they will route to agent2 if they become ready.
Checked WDE (v8.5) and SIP Server (v81) options which sound like they would allow it but doesnt work.
thanks,
