TLS DSK Failing back to NTLM

 

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.

Re: TLS DSK Failing back to NTLM

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.

Therefore the Poly VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here

 

Also posting a log may help us to pinpoint you to the issue.

 

If in doubt please open a ticket.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

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

 

Others can try and look at the logs but in order for us to investigate anything, we need a ticket.
