New and Changed Features

The following sections describe the features that are new or have changed in this release.

New Domain Support while Provisioning

When a phone connects to a network for the first time or after a factory reset, if there are no DHCP options setup, it contacts a device activation server for zero touch provisioning. Starting with this firmware release, phones will use activate.cisco.com instead of webapps.cisco.com for provisioning. Phones with older versions of the firmware will continue to use webapps.cisco.com. Cisco recommends that you allow both the domain names through your firewall.
