Automatic Port Synchronization
When the Cisco Unified Communication Manager administrator uses the Remote Port Configuration feature to set the speed and duplex function of an IP phone remotely, loss of packets can occur, if one port is slower than the other.
The Automatic Port Synchronization feature synchronizes the ports to the lowest speed among the two ports, which eliminates packet loss. When automatic port synchronization is enabled, it is recommended that both ports be configured for autonegotiate. If one port is enabled for autonegotiate and the other is at a fixed speed, the phone synchronizes to the fixed port speed.

Call History Enhancement
With this release, the Call History screen and functions are enhanced as follows:
•
–
–
In the main Call History screen, call groups can be deleted. A call group is considered to be a single entry, so if the user presses the Delete softkey for the grouped entry, the entire group of calls, not a single call, will be deleted. The user can delete the group of calls from the main Call History screen or from the Details screen.

SIP firmware support for Cisco Unified Video Advantage
The Cisco Audio Session Tunnel (CAST) protocol establishes communication between the Cisco Unified Video Advantage (CUVA) and Cisco Unified IP Phones (SIP), which enables the CUVA to support video on the PC even if the IP phone does not have video capability.
When implemented on SIP phones, the CAST protocol enables communication with video applications when the PC is connected to the PC port on the phone.
The following phones support the CAST protocol:

Cisco Unified Communications Manager Express Support
Cisco Unified Communications Manager Express supports the following IP phones:
•
•
•
Device Un-registration
The phone implements a new alarm that is sent in at the time of registration reporting diagnostic information related to the current and previous registration events, as well as, the previous deregistration event. Once the new alarm is implemented the phones, utilizing SCCP, should discontinue sending the StationAlarm message that was previously sent at the time of registration. For reference this is the alarm that includes the "Last=" string. Since this alarm is sent prior to protocol version negotiation it is understood that the newer versions of phone software always sends the newly defined StationEnhancedAlarmMessage. The older versions of the Cisco Unified Communication Manager ignores and discard the new alarm.
Bluetooth Handsfree Profile
The Bluetooth Handsfree Profile offers enhanced call-processing services (such as redial, reject, callerID, 3-way calling) while the user is connected to the Bluetooth application on the Cisco Unified IP Phone 9951 and 9971.
In firmware release 9.1(1), the existing Headset Profile has been replaced with the Handsfree Profile.
In addition to the Bluetooth qualified inter-operability requirements, the high-level call control, device management, and media service applications on the phone have been enhanced to support the Handsfree Profile. The Cisco Unified CM Administration displays a "Handsfree" option for Bluetooth Profiles.
These Cisco Unified IP Phones (SIP) support this feature:
•
•
Http Download
The download process is enhanced to first attempt to download all files using HTTP. If an HTTP connection is rejected the phone falls back to downloading using TFTP. If a timeout or file-not-found error is returned the phone proceeds in the same manor as when these errors are returned using the TFTP protocol. The fall back to TFTP only occurs if the TCP connection is rejected by the specified TFTP Server. This behavior is isolated in the download process so that the application layer sees only the normal error codes returned by file request. Note that for both HTTP and TFTP the specified TFTP Server address is used to make the request. This enhancement increases the speed of firmware upgrades.
Peer Firmware Sharing
Peer Firmware Sharing enhances the firmware on phones in remote sites over low-speed WAN links and in enterprise LAN settings, by minimizing the firmware download traffic to the Cisco Unified Communications Manager servers and other load servers. In this release, this feature is enabled by default.

Power Negotiation
The Power Negotiation feature enables phones to connect to switches that do not support power negotiation, and enables the phone to power up the accessories up to 12.9 watts.
Power Negotiation is Enabled by default, so the phone will use Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP) protocols to negotiate power.
Cisco recommends that Power Negotiation must always be enabled (default) when connecting to a switch that supports power negotiation. If disabled, the switch may disconnect power to the phone.
For switches that do not support power negotiation, disable Power Negotiation before you power up accessories over Power over Ethernet (PoE). With Power Negotiation Disabled, the phone can power accessories up to 12.9W.
When Power Negotiation and CDP are disabled, the phone can power accessories up to 15.4W.
Note
Power Negotiation is enabled by default. To change the setting of Power Negotiation to Disabled, select Disabled in the Power Negotiation drop-down list box in the Phone Configuration window, Product Specific Configuration.
The Power Negotiation feature is supported on the following phones that are running SIP:
•
•
•
VDI Client
This release supports a virtual desktop infrastructure (VDI) client, which attaches to the Cisco Unified IP Phone. The VDI client provides a virtual environment that allows users to work and collaborate from any device and location at any time.
The VDI client is supported only when it is powered by Cisco IP Power Cube.

WPA2/AES Encryption with CCKM
Cisco Centralized Key Management (CCKM) is an Authenticated Key Management (AKM) extension that is enabled in Wi-Fi Protected Access (WPA2) to optimize secure roaming. Advanced Encryption Standard (AES) is a standard mode of encryption for more secure WPA2.
Cisco Centralized Key Management (CCKM) uses a fast keying technique that enables wireless roaming from one access point to another, without going through the controller to access the RADIUS server. This results in a faster roam time, that is, less than 150 milliseconds (ms).
This helps to ensure that a SIP endpoint user experiences no delay or distortion.
The Cisco Unified IP Phone 9971 support the WPA2/AES encryption.

Whisper Coaching
Silent call monitoring is a feature that allows a supervisor to discreetly listen to a conversation between an agent and a customer without allowing the agent to detect the monitoring session. Whisper coaching is an enhancement to silent call monitoring feature that allows supervisors to talk to agents during a monitoring session. This feature provides applications the ability to change the current monitoring mode of a monitoring call from Silent Monitoring to Whisper Coaching and vice versa.
To enable Whisper Coaching in the Cisco Unified Communications Manager Administration application, choose Device > Phone, locate the Cisco Unified IP Phone that you want to configure. Scroll to the Device Information Layout pane and set Built-in Bridge to On or Default. If Built-in Bridge is set to Default, in the Cisco Unified Communications Manager Administration application, choose System > Service Parameter and select the appropriate Server and Service. Scroll to the Clusterwide Parameters (Device - Phone) pane and set Built-in Bridge Enable to On.

Using a Plantronics Audio 615M Headset with the Cisco Unified IP Phone 8961
The Plantronics Audio 615M headset is not compatible with the Cisco Unified IP Phone 8961. You must use an alternate headset type for this IP phone. For more information, refer to CSCth71104.
Using a USB Hub During an Active Call
If you use a USB hub on your IP phone or expansion module, do not unplug the hub while you are on an active call. Unplugging the hub in this scenario may cause the IP phone or expansion module to reboot. For more information, refer to CSCtf46146 using the Software Bug Toolkit.
Using a USB Headset
When you use any USB headset that uses an external power source with the Cisco Unified IP Phone, the headset must be used with external power connected only.
Note
Note
Using the Plantronics CS50 USB Headset with the Cisco Unified IP Phone Color Key Expansion Module
The Plantronics CS50 USB headset causes the phone to request power from switch even though it is self-powered. In this case, if a device such as a camera or expansion module is connected and active on the phone, the switch will reject the power request for the headset because the power budget has been exceeded. In this case, the headset cannot be used.
One-Way Video Calls for the Cisco Unified IP Phone
Due to limitations in the H.264 video signaling standards, Cisco Unified IP Phones 9951 and 9971 may not correctly display video received from devices supporting resolutions greater than 640x480. In this case, the user will see a black video screen.
To insure that video from such devices is properly displayed on the IP phone, the best solution is to configure high definition phones and Cisco Unified IP Phone 8961, 9951, and 9971 into different call regions and limit the video bandwidth to 384 kb/s when calling between regions.
Cisco Unified IP Phone 9951 and 9971 Power Negotiation when using a Video Camera
There is an issue (CSCtf09186) with some 802.3af switches, which results in the Cisco Unified IP Phone 9951 and 9971 unable to negotiate for the additional power required to operate the IP phone's camera. To power the camera, use the Cisco Unified IP Phone 9951 and 9971 phone's Power Negotiation (Enabled/Disabled) parameter to disable the IP phone's power negotiation. To disable Power Negotiation parameter access the Product Specific Configuration of Cisco Unified Communications Manager 8.5 and later releases. A device pack must be installed to add the configuration parameter to the database for Cisco Unified Communications Manager releases before 8.5. Disabling power negotiation enables the IP phone to power up the camera and to use up to 15.4 watts (the AF maximum) without the need to negotiate with the switch. Use this workaround until the switch software is updated with a fix.
Tracking the Cisco Unified IP Phone 9971 Using Cisco Emergency Responder
You must configure the Cisco Unified IP Phone 9971 in Wi-Fi mode. When using this phone in this mode, you need to configure Cisco Emergency Responder appropriately for tracking wireless IP phones. For more information, refer to Chapter 5 of the Cisco Emergency Responder Administration Guide 8.0.
Web Access Disabled by Default
Access to all web services, such as HTTP and SSH, are disabled by default on the Cisco Unified IP Phone 8961, 9951, and 9971. Your administrator can enable this feature by using Enterprise parameters.
