Default Back to All Calls

The 9.2(3) Firmware Release introduces an improved All Calls feature that allows a user's phone to automatically return to the All Calls filter view for the next call.

Previously, users had to press a function key to return to the All Calls filter view. But with this feature, the administrator can now configure a user's phone to default back to the primary line—with the All Calls filter view active—when a call has been completed.

To have a phone return to the primary line with the All Calls filter view active, you must enable both the Show All Calls on Primary Line and the Revert to All Calls features.

If you enable just the Revert All Calls feature, the phone displays the All Calls filter view but it does not default to the user's primary line. And if primary line or Alerting Calls filter is selected, reverting to All Calls will not happen.

This optional feature is available for the following Cisco IP Phones (SIP):

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

This optional feature requires administrators to install a service pack on the Cisco Unified Communications Manager.

One Touch Private Line Automatic Ringdown

The 9.2(3) Firmware Release introduces an enhancement that makes it easier for users to dial pre configured phone numbers, with the One Touch Private Line Automatic Ringdown (PLAR) feature. Previously, the PLAR feature required you to press two keys—the PLAR line and the session key to process the call. Now, when you select the PLAR line, the call session automatically appears and processes the call, making it easier for you to call emergency or hotline numbers.


Note With the One Touch PLAR feature, the phone issues a new call from a PLAR line only when that line is idle. If the PLAR line is not idle then the call is treated as a normal call, with the existing call displayed and no new call session created.


This feature is available on the following Cisco IP Phones (SIP):

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

Support for USB Headsets

With the 9.2(3) Firmware Release, the following Plantronics USB headsets are now supported:

BlackWire C220 Series

BlackWire C420

Blackwire C620

Savi 7xx

Voyager Pro UC v2

Use these USB headsets with the following Cisco IP Phones (SIP):

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

Support for Hold Button on USB Headsets

This feature provides support for USB headsets that are equipped with a Hold button. Users can put a

call on hold using the headset button and retrieve the call using the Resume softkey on their phone.

It is supported on the following headsets:

· BlackWire C420

· Blackwire C620

· SAVI 7xx

You can use this feature with the following Cisco IP Phones (SIP):

· Cisco Unified IP Phone 8961

· Cisco Unified IP Phone 9951

· Cisco Unified IP Phone 9971

Enhanced Version Negotiation with Unified CME

The Enhanced Version Negotiation with Unified CME feature offers an improved conferences call flow process for the following Cisco IP Phones (SIP only):

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

This feature makes use of special tags within software messages with the Cisco Unified Communications Manager Express (CME) to control whether a local or network hardware conference bridge is used.

Where to Find More Information

For additional information, see the following document:

Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified CM 8.6 (SIP)

Alerting Calls

The Alerting Calls feature allows users to view a list of all Alerting Calls in chronological order (oldest to most recent). Users interact with this feature using a programmable line key, which makes it easier to interact with Alerting Calls that are received across multiple phone lines.

The system administrator sets up the Alerting Calls button from the Cisco Unified Communications Manager (Unified CM) Administration. This feature is compatible with Unified CM 8.6(2) and later.

This feature is available on the following SIP phones:

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

Busy Lamp Field for Call Lists

The Busy Lamp Field (BLF) for Call Lists feature is an Enterprise parameter that the administer controls. This feature enables the user to see the presence status of monitored line numbers in the Call History list.

When the BLF for Call Lists parameter is set to Enabled, the phone line numbers in the Call History register BLF notifications and an icon appears next to each Call History item in the Call History list. The icon notifies the user that the lines are in one of the following states:

Unknown

Idle

Busy

DND

When the BLF for Call Lists parameter is set to Disabled, the phone line numbers in the Call History list do not register the BLF notifications.

This feature is supported on the following Cisco Unified IP Phones (SIP):

Cisco Unified IP Phone 8961

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

Enable Video On/Off

The Enable Video On/Off feature improves the basic video call flow by removing the blacked out screen that is displayed when one party has the Auto Transmit setting on their phone set to Off.

Users access this feature through the Enable Video On/Off setting on the phone menu. When they select On, they establish the phone as a video endpoint. When they select Off, they remove the ability of the phone to send video; all calls are audio only.

This feature works in conjunction with Auto Transmit. If the Enable Video feature is set to Off, it overrides the Auto Transmit setting and you can send audio calls. But if Enable Video is set to On and Auto Transmit is set to Off, the video stream is muted and the user sends a blacked-out screen to the other party. For this feature to function, Cisco recommends Auto Transmit remains On.

The Enable Video On/Off feature functions like Video Capability: Enable/Disable on Cisco Unified Communications Manager (Unified CM). However, the server settings override the phone settings so if video is disabled on the Unified CM, this feature is not available on the phone and all calls are audio only.

This feature is available on the following Cisco IP Phones (SIP):

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

Call History for Shared Line

The Call History for Shared Line feature offers enhanced viewing of shared line activity in the Cisco Unified IP Phone call logs. In addition to logging missed calls for a shared line, this feature logs all answered and placed calls on a shared line.

This feature is supported on the following Cisco Unified IP Phones (SIP):

Cisco Unified IP Phone 9951

Cisco Unified IP Phone 9971

VPN Capability for the Cisco Virtualization Client VXC 211X


Note Update (July 2012) - If you use the Cisco VXC VPN feature, Cisco recommends that you upgrade to Firmware Release 9.3(1). Firmware Release 9.3(1) is the official supported release for the Cisco VXC VPN. Many performance and user experience issues present in the 9.2(3) firmware are fixed in Release 9.3(1).


The Cisco Virtualization Experience Client (VXC) 21xx devices provide the capability of an integrated VPN solution for Cisco users. It will allow a remote user to have an office worker's experience with a direct connection to their organization's network while achieving lower operating costs. By providing a seamless integrated solution, Cisco simplifies the home solution deployment for the worker and enterprise.

This feature enables VPN tunneling for the Cisco VXC 2111 and Cisco VXC 2112 clients when they are attached to a Cisco Unified IP Phone 8961, 9951 or 9971. It will only provide support for wired Cisco VXC 2111 and 2112 devices to Cisco Unified IP Phone 8961, 9951 or 9971.

Also there is no support for management of the VXC via the VXC Manager (VXC-M) when the device is connecting through the VXC VPN.

One-Way Video Calls for the Cisco Unified IP Phone

Cisco Unified IP Phones 9951 and 9971 Power Negotiation when Using a Video Camera

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, see CSCth71104.

Using the Plantronics CS50 USB Headset with the Cisco Unified IP Color Key Expansion Module

The Plantronics CS50 USB headset causes the phone to request power from the switch even though the headset 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

Because of limitations in the H.264 video signaling standards, Cisco Unified IP Phones 9951 and 9971 may not correctly display video that is received from devices supporting resolutions greater than 640 x 480. In this case, the user will see a black video screen.

To ensure 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 Phones 8961, 9951, and 9971 into different call regions and limit the video bandwidth to 384 kb/s when calling between regions.

Cisco Unified IP Phones 9951 and 9971 Power Negotiation when Using a Video Camera

An issue (CSCtf09186) with some 802.3af switches results in the Cisco Unified IP Phones 9951 and 9971 being unable to negotiate for the additional power required to operate the IP phone camera. To power the camera, use the Cisco Unified IP Phones 9951 and 9971 Power Negotiation (Enabled/Disabled) parameter to disable the IP phone power negotiation. To disable the 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 earlier than 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. You must use this workaround until the switch software is updated.

Documentation Updates

This section provides documentation changes that do not appear in the existing Cisco IP Phone 8961, 9951 or 9971 (SIP) documentation:

VPN Capability for the Cisco Virtualization Client VXC211X

VPN Capability for the Cisco Virtualization Client VXC211X


Note Update (July 2012) - If you use the Cisco VXC VPN feature, Cisco recommends that you upgrade to Firmware Release 9.3(1). Firmware Release 9.3(1) is the official supported release for the Cisco VXC VPN. Many performance and user experience issues present in the 9.2(3) firmware are fixed in Release 9.3(1).


The Cisco Virtualization Experience Client (VXC) 21xx devices provide the capability of an integrated VPN solution for Cisco users. It will allow a remote user to have an office worker's experience with a direct connection to their organization's network while achieving lower operating costs. By providing a seamless integrated solution, Cisco simplifies the home solution deployment for the worker and enterprise.

This feature enables VPN tunneling for the Cisco VXC 2111 and Cisco VXC 2112 clients when they are attached to a Cisco Unified IP Phone 8961, 9951 or 9971. It will only provide support for wired Cisco VXC 2111 and 2112 devices to Cisco Unified IP Phone 8961, 9951 or 9971.

Also there is no support for management of the VXC via the VXC Manager (VXC-M) when the device is connecting through the VXC VPN.

Table 3 compares the characteristics of single and dual tunnels.


Note The VPN function uses a dual tunnel approach - one tunnel for the phone's VPN and a second for the VXC.

Note Note: Single Tunnel will be an optional feature released in the near future.


Dual Tunnel - Number of Logins:

1. In most cases, the normal use case will be two logins, one for the Phone's VPN and one for VXC_VPN.

2. In one circumstance a single-sign on is featured, but it is dependent on the power up procedure with the VXC 21xx. The user will have to enable the Phone's VPN and then proceed to power on the VXC 21xx. Once VXC 21xx is powered on, the user can enter the username/password and then login. Both phone's VPN and VXC_VPN will be connected.

3. For one-time passwords, you will enter your login credentials twice - once for the Phone's VPN and again for the VXC VPN. Users will not see a successful connection message displayed after signing into the Phone's VPN login. Instead, a successful login will display after logging into the VXC VPN.

The Cisco Unified IP Phone 8961, 9951, or 9971 and the Cisco VXC 2111 and Cisco VXC 2112 clients use identical VPN access credentials and control parameters. To enable the Cisco VXC feature, you must set up the VPN feature in Cisco Unified Communications Manager Administration, using the submenus under the Advanced Features > VPN menu path.

In addition, you must set the Enable VXC VPN for MAC Feature option to be the string FFFFFFFFFFFF. A value of FFFFFFFFFFFF allows all VXC users to complete the VPN tunnel.

If you set the Enable VXC VPN for MAC Feature option with a specific MAC address, this feature is enabled but it allows only a VXC user with the same MAC address to complete the VPN tunnel.

Use the Phone Configuration window (Device > Phone) to access this setting.

After the VXC VPN feature is enabled and the user signs in to the Phone's VPN, the phone initiates one VPN tunnel for phone traffic and a second data tunnel, VXC_VPN, to carry Cisco VXC traffic. In this case, both tunnels use the same configuration parameters.


Note No configuration is required on the Cisco VXC client to support the VPN. All VPN configuration is performed on your Cisco IP phone and the Unified CM.


Additional Configuration Requirements

The following sections describe additional phone configurations that are required to support the Cisco VXC VPN feature.

Cisco Unified Communications Manager Configuration

It is recommended that you set the PC Port to Enabled on Cisco Unified CM. If the PC port is disabled, the Cisco VXC client cannot access the network. The phone provides no enforcement of this configuration.

You can set the preceding parameters in Unified Communications Manager Administration using the Phone Configuration window (Device > Phone).

VPN Head-End Configuration

The recommended VPN concentrator (head-end) for use with this feature is the Cisco ASA 5500 Series Adaptive Security Appliance. To support the Cisco VXC VPN, you must set up the ASA for multisession support so that the phone can establish two tunnels using the same credentials.

Access Control List

The Access Control List (ACL) restricts network traffic to the display ports only. Table 4 shows the common ports and their corresponding protocols.

The following limitations and restrictions apply when using the Cisco VXC VPN feature:

Only Layer 3 packets are tunneled. The Cisco VXC VPN feature does not support Layer 2 tunneling and any Layer 2 capabilities are lost when the Cisco VXC connects through VPN.

The VPN client supports only IPv4 addresses.

The VXC VPN tunnel cannot be established over a Wi-Fi interface.

You can configure the Enable VXC VPN Feature option after you set up the phone VPN parameters, including VPN Group and VPN Profile. This restriction exists because the VXC VPN shares the same VPN parameters as the phone VPN.

All existing limitations and restrictions related to the phone VPN support apply to the VXC VPN as well.
