My phones are already configured using Lync base profile, and do I still need Lync.cfg file? Are serverAutoDiscovery and autoProvisionCertLocation included in the Lync base profile?
since UCS 4.1.0 a Option 43 Device Certificate and Option 120 SIP server similar to our CX Phones should be sufficient.
In addition you could set the Phones to boot straight into Pin Auth Mode so it is exactly as the CX Phones.
Once I find some time I will update the LYNC FAQ Post.
Thanks for responding my post. Does UCS 4.1.2 still require VVX500 to downloand Lync server certificate? I couldn't find information on how to import cert to the phone.
A cert is always required.
I suggest you google for our Polycom Guru Jeff Schertz's blog's as he describes it all in detail.
Our CX Phone range utilizes DHCP option 43 with 5 sub options to provide the link to the certificate for the phones.
Please be aware of the following when utilizing UCS 4.1.0 or later:
