Hi Daniel,
thank you for a reply. I have managed to solve it in a different way.
In a first message I forgot to add that I'm calling uac_replace_from before
mentioned code. I have moved uac_replace_from function, so it is called
after the dlg_manage function and right now only one callback is
registered. This fixed it.
Isn't it possible to un-register the first callback when the second one is
registered?
Kind regards
Efelin
