I migrated from Lync 2010 to 2013 Server successfully. However I still have a problem with the any UCupdate higher than4.0.7577.4100 when using pin authentication with Polycom CX600 phones. We basically have two sip domains: domain.eduand domain.org. Domain.edu is our external and domain.org is our internal. When using pin authentication on with any UCupdate higher than4.0.7577.4100 pin authentication fails for users on the .edu domain but is successful on the .org domain.
So basically there is two problems:
1 - Domain.edu is our primary sip domain for user and it keeps us from deploying any newer UCupdates because of the sign in issue.
2 - I cannot find a download of the .4100 UCupdate; I get redirected to the very latest which doesn't operate with both our sip domains.
On my Lync Server Share I can see that the actual files for .4100 are in the Webservices-1 and Webservices-6 directory respectively, however I'm not sure what PowerShell command I could run to import them without pointing to the UCupdate.cab file since I can't download the older .cab that I need.
Has anyone seen this before? I can't understand why the older version works for both domains but anything higher fails. Not sure whether it's cert related or not.
I could use a hand on this one.
