In this article, I have shared a set of pre configured and optimized .cfg files that can be used with any Lync server deployment. Granted that some of the parameters need to be changed according to the environment and I will explain what need to be changed and why.

There are 6 configurations files all together which address different segment of the device configuration.

Starting with Device.cfg. This configuration file set to configure following parameters in VVX device,

The Feature.cfg file specify the common set of features on the device such as, Call lists, Miss call alerts, Contact Directory. In this file, the specified parameters are below,

Sip-Interop.cfg is the most important one. This one controls the device registry intervals as well as the SIP Proxy server related parameters. In this configuration file, most of the parameters haven’t changed. But, the ones that were changed are below,

The Site.cfg file is configured to set daylight saving time in to the device. If the daylight saving is applicable, the start and stop times need to be configured,

Lync.cfg file configured to set BToE enabled. But, in version 5.1.1 Revision B, Polycom have set the BToE as disabled and given that the configuration file version is 5.2, this configuration file doesn’t really enable BToE on version 5.1.1 Revision B firmware. But, it can be used on Version 5.2.

The Cer.cfg is set to import the root CA in to the device. 90% of the devices that I have deployed were able to get the certificate without uploading manually. In case the device fail to pick up the certificate, copy and paste the hash file of the CA certificate in to the configuration parameter.

Finally, the Master configuration file 000000000000.cfg. All the above mentioned configuration files are specified in this master configuration file. When the device boots up, it will fetch the configuration mentioned on this files and get configured based on parameters which are configured on each sub configuration file.
