configure each UC endpoint manually, this can be helpful in situations that require the mass deployment of UC endpoints, this
method will make the provisioning process efficient and optimized, in our GHP6XX/W IP hotel phone series, the zero config is

2. Select menu "Other Services" – "Zero Configuration" – "Model Update".
Select a phone model and click the Download and Install button on the right of the list to download the model
configuration file to the UCM.

the file of the UCM zero-configuration template (.pack file) and click the Download and Install button.
