We've on-prem Skype 2015 with Trio8800 5.9.1.10419
I belive we seeing a reoccurnace of the issue previoulsy described here https://community.polycom.com/t5/Skype-for-Business/TLS-DSK-Failing-Back-to-NTLM/m-p/98907 Poly reference 1-9138231445 / EN-90495 / EN-101200.
Anyone else seeing this with NTLMv2 and Trio with the latest firmware?
Hello @JamesW ,
Stating the latest software does not help others when finding this post in days, weeks, months or years to come as they do not know what software mentioned was current at the time of writing.
Please therefore always post the exact complete build id.

The firmware version was in the first line.
Logs look very similar to the previous occurance of this issue. You can see 401 and 403 errors back from the webservices URL, but the registrar accpets the same credentials as does exchange EWS.
Hello @JamesW ,
The currently latest software is 5.9.1.10906 Rev AB and not 5.9.1.10419 Rev AA
