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

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? чт, 14 мая 2020 г., 23:02 David Villasmil < david.villasmil.work(a)gmail.com&gt;gt;: > This looks Fs-related, not kamailio. > > On Thu, 14 May 2020 at 20:25, Yuriy Nasida &lt;ynasida(a)gmail.com&gt; wrote: > >> I do not want MS to initiate a separate call leg.
