I'm not sure if this is even meant to work as I'd like it to, or whether I need to change a configuration somewhere.....

When a call is transferred to another extension using attended xfer, fop2 does not update the display (it's fine with blind xfers).

For example if A transfers a call to B, fop correctly clears-down the status on A, but B is shown as still talking to A and not the caller that was transferred to B

This is with FOP2.20 (and tried 2.21 Beta), SIP channels for the phones, callevents is enabled in the sip settings.

We're using P-Asserted headers and the phones correctly update when a call is transferred.

Any ideas?
Cheers,
Andy.
