There is something strange going on when my operator receives a queue call. In fact that is how she receives all calls, as her extension is part of several queues.
She picks up the calls from the panel using her mouse.
She then can't make a supervised transfer (clicking the action button has no effect) and when transfering to a mailbox using the transfer to mailbox action button, the call hangs up.

None of this is happening when she has either initiated the call, or received a call on her extension directly not coming from the queue.

Can you help?
