Willen,
can I suggest you buy a new cordless phone.
My post #17 was pretty clear that you cannot really test these things. If you have no test gear and its only a cordless phone then take the least cost way and buy a new phone. If you want to get involved with this type of semiconductor, then buy an old 2 way radio (ex taxi etc), and try to get something working that has some value.
I'm only trying to be helpful.
If you look carefully at all the posts, most of them aren't helping you; they are only crosstalk between others discussing your problem but not solving your problem in terms that helps YOU.
