Experienced with most actual 3CX Version 15. If calls are blind transferred, there is shown on the final destination extension the number of the blind transferrer instead of the initial (real) caller. This is quite useless as the person receiving the blind transferred call doesn't see who is really calling, even worse he sees in this simple and daily usual situation the wrong caller. This seems to be quite critical bug. This is easily reproducible for internal and external callers.
