Problem:
Phone A is redirect to phone B.
Phone B calls phone A an get a busy tone.
Ok, I know there is a loop detection for the case, that phone B is redirected to phone A.
But isn't there any rule like:
Redirect the call exept the call comes from the phone to whom it will redirect in normal case.
This is important for us because our director redirect his phone to his secretary. When she gets a call destinated for the director she tries to transfer the call to him and this will fail.

Hi Holger,
There is a feature, which is called "CFA Destination Override". Have a look;
Cisco Unified CallManager provides a service parameter (CFA Destination Override) that allows the administrator to override Call Forward All (CFA) when the target of the CFA calls the initiator of the CFA, so the CFA target can reach the initiator for important calls. In other words, when the user to whom calls are being forwarded (the target) calls the user whose calls are being forwarded (the initiator), the phone of the initiator rings instead of call forwarding back to the target. The override works whether the CFA target phone number is internal or external.
When the CFA Destination Override service parameter is set to False (the default value), no override occurs. Ensure the service parameter is set to True for CFA override to work. See Service Parameters Configuration in the Cisco Unified CallManager Administration Guide, Release 5.0(4), for information about configuring service parameters.
--------------------------------------------------------------------------------
Note CFA override only takes place if the CFA destination matches the calling party and the CFA Destination Override service parameter is set to True. If the service parameter is set to True and the calling party does not match the CFA destination, CFA override does not take place, and the CFA remains in effect.
From this CUCM doc;
This only works from the phone that the Call Forward All is directed to. I would suggest adding a second line (non-listed) to this IP Phone specifically for Emergency calls. The Call Forward All will only effect Line 1 so you would be good to go
Hope this helps!

Assuming he is now using Call forward all - I would doubt very much there is a rule that breaks another that keeps the system from looping.
Just a couple thoughts...
If the director has an open button the easiest way to provide functionality would be to give him a second "private" line that the secretary can transfer the call to.
Alternatively you could put the directors line on the secretary's phone as a shared line and add the DND key to his phone. He would press that key when he didn't want to be disturbed and she would pick up the calls on her phone. If you added an intercom key for her she could use that to ask him to pick up the shared line when she wanted to route the call to him.
HTH,
