Table 1 Resolved Problems

Bug ID	Summary
CSCdy70295	Cisco IP Phone sends an unused message to Cisco CallManager. This does not cause any adverse behavior because Cisco CallManager simply rejects the unused message.
CSCdz07715	Call quality statistics do not display on the called party phone. With the resolution of this problem, the called party Cisco IP Phone captures the statistics at the end of the call so they can be obtained after the call concludes.
CSCdz25776	If the Cisco IP Phone receives improperly formatted text (not XML), then the Cisco IP Phone may lock up.
CSCdz30859	Cisco IP Phone handset Send and Receive response has a faster rolloff at high frequencies.
CSCdz42155	Cisco CallManager displays as two words in the Cisco IP Phone 7960/7940 under Network Settings.
CSCdz52758	A large max jitter value displays when the timestamp in an RTP stream changes in the negative direction and the magnitude of that change is larger than the jitter buffer can handle. The jitter buffer discards a large number of packets, and the audio may cut out for 1 or 2 seconds after the change.
CSCdz53716	Cisco IP Phone always sends StationTimeDateReq at 00:00, 10:00, 20:00, which may cause a dial-on-demand routing-configured interface to come up at an unexpected time.
CSCdz55651	The number of lost packets that the Cisco IP Phone reports in a Skinny protocol Connection Statistics message is invalid.
CSCdz60350	Cisco IP Phone resets when the Dial soft key is pressed in the Corporate Directories if the Cisco IP Phone is not associated with a user.
CSCdz71206	During a conference, a Cisco IP Phone with shared line appearances displays an empty line when the conference is placed on hold and a new call is attempted.
CSCdz73254	Cisco IP Phone 7960 with two 7914 expansion modules displays a cursor when a directory search is performed immediately after log in with extension mobility occurs.
CSCdz73839	When the ring type is set on a Cisco IP Phone 7960/7940, lifting the handset causes the phone to ring.
CSCdz82032	Cisco IP Phone 7960/7940 does not guard against invalid timestamps in G.729 RTP stream from Cisco Conference Connection.
CSCdz84738	On outgoing calls, a DSP TIMEOUT may display on the screen, followed by one-way audio.
CSCdz85700	Cisco IP Phone does not properly display the list of missed calls after two calls that were forwarded on a no-answer condition.
CSCea03093	When operating in SRST mode, Cisco IP Phone 7960 does not have a directory number.
CSCea29947	UDP checksum gets ignored.

Table 2 Known Problems 

Bug ID	Summary	Explanation
CSCdt95739	Caller ID overwrites the call park number.	If many calls are incoming to one site and if a call is placed on park and an incoming call comes in immediately, the call park number gets overwritten on the display and the user cannot note the number. Workaround: None.
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 it is failing to do so. Workaround: None.
CSCuk35195	Large variation in jitter occurs on speech path from VISM to phone.	A high jitter occurs 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.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
