Re: [SR-Users] REFER from MS teams to 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.
