Last leg of supervised transfer not recording

The last leg of a supervised transfer is not recording when the extension it terminates on is set to force.

I have 3 extensions set to record (via force option on the extensions) inbound internal and inbound external calls. The idea is to capture customer conversations but they transfer calls around (hence the internal recording). Call flow is inbound call -> ring group -> someone answers and then transfers to the right person.

They complain they never see the customer recording. What it appears is going on is that they are doing a supervised transfer to the final destination of the call telling them what's up before the call gets transferred. I have recordings from the initial call and the supervised part of the transfer. But when they call is sent to the final destination there is no recording.
