New and Changed Features

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.

Limitations and Restrictions

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect phone voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks, such as an internal port scan or security scan

  • Attacks that occur on your network, such as a Denial of Service attack

Caller Identification and Other Phone Functions

Caller identification or other phone functions have not been verified with third-party applications for the visually or hearing impaired.

No Beep Sound Heard when the Mute Key is Pressed

When you press the Mute button during a call, you may not hear a beep sound. For anyone who is visually impaired, press the Mute button once to mute the phone and press the button twice to unmute the phone.

Phone Has a Firmware Build Earlier than 11.0.0

Sometimes, a phone taken out of the box has a firmware build earlier than 11.0.0. When this happens, you must upgrade the firmware on your phone to 11.0.0. Then you must update to 11.1.1 or later before you provision it.
