I have a problem logging on to Skype for Business on-premise with 2 different Skype room systems.
Both are on version 188.8.131.52 and I am seeing this error message: we can't sign you in because the server couldn't be reached or the server version is incompatible
The customer has firstname.lastname@example.org as the SIP address and has domain2.no locally. I have put both domains in the configuration page on the SRS. I have also tried the registry fix HKLM\Software\Microsoft\SkypeRoomSystem Trustedmodeldata = "all domains configured"
I have tried to connect one of the SRS through internet, then it authenticates with the edge server, same problem.
Is there anybody that has a solution for this?
PS: I know they work, tried to connect to another Skype for Business org and it works. Also work onOffice 365.
