I personally chose the option of not removing the REFER from supported
methods. Had to handle in a custom way the attended transfer context in
Asterisk (my choice of B2B). I don't know how it is in FS.
Good luck.

Yes, Kamailio just send MS refer to FS.
In my opinion it is MS related, because their REFER is weird. This list
have members who did MS integration with Kamailio. That is why I would like
to ask if you get attended (consult), transfer working with MS (with refer
or without refer - it doesn't matter). Do you handle refer at kamailio
somehow?

This looks Fs-related, not kamailio.

I do not want MS to initiate a separate call leg.
I want to get
attended (consult) transfer. I call from A to B. Next call from A to C.
Next, I want transfer B to C.
B and C is pstn numbers (i.e. not MS side).
I expect 2 variants:
1) Without REFER support at kamailio. I expect MS just will do
transfer B-->C at MS side. But MS send one more INVITE to C Instead of
this. i.e. C side already has the call. I do transfer and.. C side gets
one more call instead of transfer.
2) Kamilio support REFER and send it to FS. FS should transfer such
call inside itself (like it does for REFERs from zoiper or other usual
softphones).
But... MS sends weird REFER and FS can not handle it it the same way
like FS does for zoiper.
Please advice.

Remove the REFER from Supported header if you
want MS to initiate a
separate call leg, it's described in the direct dialing documentation.
Cheers.
