Atxferabort not working

Hi to all,
I’d like to have the possibility to get back a call I had initiated an attended transfer for. This should be possible by the atxferabort feature, right?

So, in my features.conf I have

[featuremap]
atxfer => *2 ; Attended transfer – Make sure to set the T and/or t option in the Dial() or Queue() app call!

and

[general]
atxferabort = *1 ; cancel the attended transfer
atxfercomplete = *2 ; complete the attended transfer, dropping out of the call
atxferthreeway = *3 ; complete the attended transfer, but stay in the call. This will turn the call into a multi-party bridge
atxferswap = *4 ; swap to the other party. Once an attended transfer has begun, this options may be used multiple times

Initiating the transfer works fine, but when I press *1 nothing happens but asterisk telling me that I chose an invalid number.

When I set debug on, I can see, that the dumf-tones are submitted:

Can anybody point me to my mistake?

BTW, I set the “t”-option in the dial()-application:
