Dhcp dns updating
How can a device which cannot register to the server download an update from the server when it needs to first register to be provided the device update server information?
This might mean that the device would instead need to be connected to and registered to Lync 2010 server first, then updated to CU7 or higher, no? There is one alternative which would allow any previous version of Lync Phone Edition to download an update package directly from a Lync 2013 server without even the ability to first successfully register to it.
The registration does not need to actually succeed so if the phone is running a vey old version incapable of registering to the Lync server for some reason, or an invalid PIN is used simply to speed up the process it does not matter.
Simply initiating the registration process is sufficient to trigger the root certificate retrieval process via DHCP Option 43.
Typically the certificate issued to the Lync Front End server is from an internal private Certificate Authority, which unfortunately means the device cannot automatically download the update without intervention.
Microsoft continues to release semi-quarterly Cumulative Updates of firmware for the various LPE models.
In the round of releases in December 2012 and January 2013 (aka CU7) official support for Lync Server 2013 was added, as well dropping the ‘2010’ from the previous name of .
All that is left now is to return the phone to main menu and leave it ide to do its thing.
It is important to not leave the phone at the failed Desk Phone Setup screen pictured above otherwise the update process will not begin.
