@DigitalDaz Do you mind to share your kamailio config once again? I got the connection between Teams <-> Kamailio working, now struggeling (hard) with the call handling for Kamailio <-> FusionPBX. Also your adaption for multitentant would be very interresting.
I also would take any notes to bring me forward, would offer to do a clean writeup after I got it working.
Dit you get it to work?
I also have teams en kamailio working but don't know whats next..
