Obtain information about Cisco IP Telephony at the following URLs: Cisco IP Phone information: http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/index.htm Cisco CallManager information: http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/ New and Changed Information New Software Features The following new software features are supported in the P00305000101 and P00405000101 firmware releases for Cisco IP Phone 7960, 7940, and 7910 series that are running on Cisco CallManager Release 3.3, 3.2, and 3.1. Image Authentication and Signed Binary Files Cisco has added image authentication to its various IP phone protocols. The addition of image authentication prevents tampering with the binary image prior to it being loaded into the phone. Any tampering with the image causes the phone to fail the authentication process and reject that image. The image authentication occurs through signed binary files. 2 OL-4484-01
Known and Resolved Problems The P00305000101 and P00405000101 firmware releases do not use regular binary files as did previous releases but only use signed binary files. This step improves IP phone security on the Cisco IP Phone models 7910 and 7940/60. However, the use of signed binary files does not allow downgrading to an earlier software release. After the P00305000101 or P00405000101 firmware release is installed, you cannot replace it with any previous release. Note After the P00305000101 or P00405000101 firmware release is installed, you can replace it only with the same or newer release. All releases prior to the P00305000101 or P00405000101 firmware release will not function on this phone after this release has been installed. If you revert the cluster to Cisco CallManager Release 3.1 or 3.2, the P00305000101 or P00405000101 firmware release will function on these Cisco CallManager versions. If you have a firmware image that is older than P00305000101 or P00405000101 identified as the default image, then the IP phone will try to load the default image, will be unsuccessful, and will display file not found on the IP phone display. It will then log an error of file not found in the CCM event log, but the IP phone will continue to function by using the P00305000101 or P00405000101 firmware image that was previously installed on the IP phone. Cisco will provide all defect fixes for Cisco CallManager 3.1 and 3.2 and 3.3 firmware loads in firmware load P00305000101 and P00405000101 and later. Known and Resolved Problems Known problems (bugs) are graded according to severity level. These release notes contain descriptions of All severity level 1 or 2 bugs. Significant severity level 3 bugs. All customer-found bugs (regardless of severity level). 3

Known and Resolved Problems Table 1 Resolved Problems (continued) Bug ID CSCeb47121 CSCeb47122 Summary Very high noise heard when the Mute button is pressed on Cisco IP Phone models 79XX. Shared Cisco IP Phone continues to ring if the call is ended immediately after answering. Table 2 Known Problems Bug ID Summary Explanation CSCdy75335 DSP Keepalive Timeout message appears many times per second in Cisco CallManager traces. If you see the following message repeated many times per second in the Cisco CallManager traces, StationInit: 14f73d50 Alarm alarmseverity=7 text= DSP Keepalive Timeout [0xffff, 0xffff, 0xffff, 0xffff], then the phone is trying to register with Cisco CallManager, but is failing. Workaround: None. CSCdz19560 CSCea77050 Sustained DTMF tone may play if a keypad number and the EndCall soft key are pressed simultaneously. When the Speaker button and Resume soft key are pressed, the display of first held call is removed. When a keypad button and the EndCall soft key are pressed simultaneously while on handset, the phone plays a sustained DTMF tone, but the screen is idle. Workaround: Press any keypad button while the tone is playing. On a phone with two calls on hold, when you use the arrow keys to select the first call, then press the Speaker button, and then use the arrow keys to select the second call and press the Resume soft key, the display of the call details for the first call disappears. Workaround: None. 5
Known and Resolved Problems Table 2 Known Problems (continued) Bug ID Summary Explanation CSCea81159 Exit soft key does not return to the previous screen but instead goes to the root directory. Pressing the Exit soft key does not return the phone display to the upper level of the directory structure/tree; instead, it goes to the root of the directory tree. Workaround: Use custom soft keys and provide URLs on the Exit soft key that point to the previous page in the hierarchy. For example, add a SoftKeyItem on the second page labeled Exit that has a URL that points to the first page, and so on. CSCea86371 CSCea89552 CSCea90298 CSCea90398 Short ring occurs when CFNA to a second line on a Cisco IP Phone 7940/60 with 3.3(2)SPB occurs. Phone does not fail over to next DNS server on RCODE=Server failure. TFTP server has to be set up again if the wrong phone load is configured in Cisco CallManager. Deleted user can access a Cisco IP Phone. Using the default load P00303030200, with a Cisco IP Phone with the second line under Ring Setting (for both phone idle and phone active) set to "Ring," only one short ring occurs instead of a continued ring. Workaround: None. Cisco IP Phone displays "Host Not Found" on an HTTP request. Workaround: Correct the server failure condition on the primary DNS server. Cisco IP Phones will not register if the wrong phone load is configured and deleted. Condition: Non-DHCP server setup. Workaround: Manually set up the TFTP server information in the Cisco IP Phone or use a DHCP server. A deleted user can access a Cisco IP Phone through http://<ipaddress>/cgi/lineinfo Workaround: Reset the phone that is associated with the deleted user. 6 OL-4484-01
Known and Resolved Problems Table 2 Known Problems (continued) Bug ID Summary Explanation CSCeb04302 Cisco IP Phone 7960 does not update its IP address after second DHCP request. Another IP phone duplicates the IP address of a registered Cisco IP Phone 7960 with DHCP enabled. After several unsuccessful attempts to register with Cisco CallManager, the phone sends another DHCP request message to the DHCP server and gets a new IP address. The phone registers to Cisco CallManager by using the new IP address, but the previous IP address still shows on the Setting > Network Configuration menu. Workaround: Reset the phone. CSCeb19725 CSCeb27021 CSCeb27137 CSCeb27733 Intermittent one-way/no-way audio may occur for the first 10 seconds of a call if TCP packets are received of out of order during the call set up. Pushing an ExecuteObject to the phone may require a double submit to work properly. Pushing an Execute tag that requires an input value to a Cisco IP Phone 7940/60 may require a double submit to work properly. Invalid characters display with help text on Cisco IP Phone 7960. Intermitent one-way/no-way audio may occur for the first 10 seconds on calls between IP phones (no gateway involved). Workaround: None Pushing the Cisco XML ExecuteObject once may cause an erroneous result to display. Workaround: With the display still showing the erroneous results, push the ExecuteObject again. The phone displays the correct results. Using a Cisco XML Execute tag, a page that contains a Cisco XML Input tag is pushed to a Cisco IP Phone 7940/60. The first time the user inputs data and presses the Submit soft key, the value that is coming back from the Input tag seems to be a NULL. The user must input the data once more and press the Submit soft key again for the data to be returned correctly. Workaround: Users must enter the input data twice. When the i or? button is pressed followed by the Redial soft key on a Cisco IP Phone 7960, the help displays along with a few invalid characters, such as 
,
. Workaround: None 7
Obtaining Documentation Table 2 Known Problems (continued) Bug ID Summary Explanation CSCeb32399 CSCuk35195 No DeviceDataPassThrough response occurs after the phone is reset. Large variation in jitter occurs on the speech path from VISM to the phone. After an IP phone opened by a CTI application resets, no response occurs after a DeviceDataPassThrough is sent to the phone. Workaround: Send another DeviceDataPassThrough immediately after the first one; you will get the response for the second DeviceDataPassThrough. A high jitter appears on speech from VISM to the Cisco IP Phone. Jitter remains constant from IP phone to VISM. This problem causes PAMS and PESQ measurements to be low on these calls. Workaround: None. Obtaining Documentation These sections explain how to obtain documentation from Cisco Systems.
