New and Changed Information
This section contains these sections:
•
Call-Forward-All Upgrade for CTI New Call Event
•
•
Call-Forward-All Upgrade for CTI New Call Event
With firmware release 9.0(3), information was added to the Computer Telephony Integration (CTI) new call event. The JTAPI and TAPI applications can now distinguish between an actual outgoing call and a call that is created when a user presses the call-forwarding softkey (CFwdALL or Forward All depending on the IP phone model), or presses the Forward All line button on the Cisco Unified IP Phone 8961, 9951, and 9971.
This enhancement applies only if the Call Forward All feature is invoked when the phone is on hook. If the phone is off hook, such as when a user lifts the handset or presses the speakerphone before invoking the Call Forward All feature, the CTI new call event will not provide the call-forward-all information.
In-service Upgrade Enhancement
The dual-banked firmware update feature allows the Cisco Unified CM administrator to upgrade phone firmware with a new load before resetting the new load to an Inactive load status. Instead of waiting for all the phones to download the firmware, Cisco Unified CM administrators can use the Switch Loads function to quickly switch from the old load to the new load in less time. Upgrading the dual-banked firmware reduces the bandwidth congestion and the delay in download during system maintenance while allowing Cisco Unified CM administrators to determine when to set the new firmware to Active load.
Note
A new area in Cisco Unified CM Administration Device Settings Configuration allows you to change the Active load and the Inactive load. Go to Cisco Unified CM Administration > Device > Device Settings > Device Defaults > Dual Bank Information area to change the load.
The In-service Upgrade Enhancement feature is supported on these IP phones running the SIP protocol:
•
•
•
Secure and Nonsecure Indication Tone
With firmware release 9.0(3), the secure indication tone functionality was updated, and the nonsecure indication tone was added to the Secure and Nonsecure Indication Tone feature for the Cisco Unified IP Phones. The 8.0(3) release of Cisco Unified Communications Manager (Unified CM) is a requirement for these changes to function.
If phone is configured as secure (encrypted and trusted) in Unified CM, it can be given a "protected" status (which is separate from the status a call). After that if desired, the protected phone can be configured to play an indication tone at the beginning of a call:
•
•
Only protected phones hear secure or nonsecure indication tones. (Nonprotected phones never hear tones.) Because the condition for playing the secure indication tone is now based on the overall secure status of the call end to end and not the protected status of the phone, users hear a tone between a protected phone and a nonprotected phone if the Secure Real-Time Transfer Protocol (SRTP) or Real-Time Protocol (RTP) is established.
If the overall call status changes during the call, the indication tone changes accordingly. At that time, the protected phone plays the appropriate tone.
A protected phone plays a tone or not under these circumstances:
•
–
–
•
These changes were also made with this release:

The Secure and Nonsecure Indication Tone feature is supported on these IP phones running the SCCP and SIP protocol:
•
•
•
Non-CDP Power Negotiation
For firmware release 9.0(3), the Non-CDP Power Negotiation feature allows the phone to use up to 15.4 watts (the AF maximum) without negotiation. You can disable CDP on the phone configuration window in Cisco Unified CM administration.
The Non-CDP Power Negotiation feature is supported on these IP phones running the SIP protocol:
•
•
•
Secure Extension Mobility
Communication exchanged between a Cisco Unified IP Phone service and other applications uses the HTTPS protocol, which ensures that all information is secure. When users log into Cisco Unified CM applications, they provide authentication information. User credentials are encrypted after the change of the communication protocol to HTTPS. Web applications with both HTTP and HTTPS support have two URLs configured. Cisco Unified IP phones that support HTTPS select the HTTPS URL; otherwise, the phone select the HTTP URL.
The Extension Mobility HTTPS Support feature is supported on these IP phones running the SIP protocol:
•
•
•
Secure SIP Failover for SRST
Firmware release 9.0(3) provides support for secure calls on a Cisco Unified IP Phone running the SIP protocol to remain secure once the call fails over to SRST from Cisco Unified Communications Manager. In addition, this feature enables the user to verify that the call is still secure by the lock icon that remains on the phone display.
For firmware release 9.0(3), when an IP phone endpoint using SIP is in a secure call that fails over to SRST from Unified CM, the user will continue to see the lock icon on the phone display, indicating the call remains secure. In previous releases, an SIP/TLS/TCP call that fails over to SRST displayed the play arrow icon to indicate a non-secure call.
The SRST supports RTP and SRTP media connections according to how the security settings are configured on the IP Phone.
The system administrator configures SRST on a Cisco router to allow endpoints using SIP to register to SRST using SIP/UDP, SIP/TCP, and SIP/TLS/TCP.
An example of a complete secure configuration for the SRST is shown below:
voice service voipsrtp fallbackallow-connections sip to h323allow-connections sip to sipsipurl sipssrtp negotiate ciscovoice register globalsecurity-policy securesip-uaregistrar ipv4:101.2.0.10 expires 3600xfer target dial-peercrypto signaling default trustpoint 3745-SRST strict-cipherThe default value for the CLI command security-policy is device-default. If the value is set to the default value, the existing transport mechanism will be accepted by and registered to the SRST on failover. If the value is set to secure, the SRST will only accept the following transport mechanisms in order to ensure the call maintains its secure state, if applicable—SIP/TLS/TCP.
An example of a complete device-default configuration for the SRST is shown below:
voice service voipsrtp fallbackallow-connections sip to h323allow-connections sip to sipsipurl sipsrtp negotiate ciscovoice register globaldefault security-policysip-uaregistrar ipv4:101.2.0.10 expires 3600xfer target dial-peercrypto signaling default trustpoint 3745-SRST
In firmware release 9.0(3), when an IP Phone endpoint using SIP is in a secure call that fails over to SRST from Unified CM, the user will continue to see the lock icon on the phone display, indicating the call remains secure. In previous releases, an SIP/TLS/TCP call that fails over to SRST displayed the play arrow icon to indicate a non-secure call.
The Secure SIP Failover for SRST feature is supported on these IP phones running the SIP protocol:
•
•
•
Trust Verification Service and Security
To support secure connections with other components, a Cisco Unified IP Phone authenticates component certificates by validating the certificates with entries in the Certificate Trust List (CTL) file, which has a 32-character maximum limit.
The Trust Verification Service (TVS) allows the phone to authenticate components without adding a CTL file entry. Adding new components or services does not require the CTL file to be updated on all of the phones.
The Security by Default feature removes the restriction that requires the user to create the CTL file by using eTokens to provide and enable security features. The signed file is enabled automatically by default.
The Trust Verification Service and Security by Default feature is supported on these IP phones running the SIP protocol:

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 USB Headset with the Cisco Unified IP 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 window.
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.
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.
