Enerywise Issue on 69xx phones, Open CSCug86591

Symptom: The switch is configured for Energywise feature to put the phone into sleep (level 2) and wake up (level 10). The only configuration on the CUCM Phone config page is the Energywise Domain & Energywise endpoint security secret for the phone to participate in the Energywise domain configured on the switch. The option "Allow EnergyWise Overrides" on the CUCM Phone Config page needs to be enabled as well. The phone should ideally wait for the signal from the switch as the wake up timer is configured on the switch. However, the 69xx phone sends a Fire in time based on CUCM "ON TIME" config to switch even though this option is disabled on the CUCM Phone config page.
Conditions: When the sleep and wake up time is configured on the switch Energywise configuration instead of the CUCM Phone config page.
Workaround: The wake up issue only occurs when the phone is configured to get into sleep mode (Level 2). If however the phone is sent into shutdown mode (Level 0) the phone wake up at the correct time configured on the switch. Therefore, as a work around we can put the phone into shutdown mode from sleep mode right before the wake-up time, else the phone will wake up only on the time configured on the CUCM Phone config page. i.e ! interface FastEthernet0/0 energywise level 2 recurrence importance 80 at 02 12 * * * energywise level 0 recurrence importance 80 at 17 11 * * * energywise level 10 recurrence importance 80 at 17 12 * * * !

Conditions: When the phone rings; ATA 187 sends caller ID signal to the analog phone between the first and the second ring (with name, phone number, TIME and date information). In the current scenario; instead of sending the actual time; ATA 187 is sending its uptime in the signal.
Workaround: Not applicable

8945 Video is unmuted on existing call if incoming 2nd call is CFNA, Open CSCug71056

Symptom: Video gets unmuted even though "Auto Transmit Video" is set to OFF.
Conditions: --SIP Firmware (seen in 9-3-2-12) --If an 8945 Phone has "Auto Transmit Video" set to OFF, the video will be on mute but once we get a 2nd call on the same line and it gets CFNA to another extension / voicemail, the video on the phone automatically gets unmuted and the existing party can now see the "caller on 8945 side" .
Workaround: No workaround

Xfer call bounces back when picked up @ ~same time as 2nd xfer keypress, Open CSCty35673

Symptom: ~~~~~~~~~~~~~~~~~ Occasionally, recipients of a transferred call pick up their ringing phone and hear dead-air. The transferring party finds that the call they think they transferred returns to them.
Conditions: ~~~~~~~~~~~~~~~~~ SIP phone acting as transferring party (e.g. observed on Cisco 8961 IP Phone) The recipient of a transferred call answers their phone right before the transferring party presses the second transfer key-press. The transferring party is thinking that they were making a blind transfer, but signaling begins for a consultative transfer. A race condition arises where CUCM starts to set up media between the transferring party and the recipient of a transfer, but then the media immediately needs to be torn down before the initial setup is complete. In the meantime, new media is being set up between the transferred party and the recipient of the transferred call. This overlapping signaling is not processed correctly by both the CUCM and phone. These symptoms are more likely to be identified as a repeating pattern by receptionists who manually answer and transfer calls.
Workaround: ~~~~~~~~~~~~~~~~~ None. Education/Modification of user behavior might reduce the likelihood of experiencing this issue - e.g. tell the transferring party that if they do a blind-transfer they do so quickly *and* informing recipients of transferred calls not to pick up immediately.

CUCI-Lync msiexec command documentation missing some options, Open CSCug25254

Symptom: CUCI-Lync documentation for msiexec command line install does not include all features available. Reference: http://www.cisco.com/en/US/docs/voice_ip_comm/cucimoc/8_5/english/installguide/deploying_installation.html#wpxref81070 Specifically, table 5-1 should include the JRE component as an installable feature.
Conditions: After command line install clients may see a CSF error ?Unable to find a supported Java Runtime Environment?." The Java Run-time Environment (JRE) can be included as installed feature as part of the CLI install.
Workaround: The Java Run-time Environment (JRE) can be included as installed feature as part of the CLI install. The install syntax will be something like the following... msiexec /i CiscoUCIntegrationTMforMicrosoftLyncK9.msi /q ADDLOCAL="CUCIMOC,JRE,Word,Excel,SmartTags,InternetExplorer,Firefox,PowerPoint"

69xx phones in hunt group are not showing alerting name of hunt pilot, Fixed CSCtn80214

Workaround: None

IP Phones - Improve transmit voice call quality when using the speaker, Open CSCug29229

Symptom: On conference calls, a user with a cisco ip phone in the speaker mode, has difficulties to interrupt other people. The other participants on the call will hear the voice of the user in lower volume an choppy. The issue is worst the higher is the speaker volume.
Conditions: Seen on CUCM 8.5 and using 9951 phones. But it should be the same on other phone models, reproduced the same on a 7975. This is only reproducible if there are at least other 2 participants in the conference call continuously talking previously to the user starting to talk.
Workaround: Lower the speaker volume. This effect is a consequence of the echo cancellation on the phones. This is an enhancement request to see if this behavior could be improved.

8945 SCCP Predot number is disappeared on Call history when using redial, Fixed CSCuf24528

Symptom: Originally, if a 8945 phone user places a call to PSTN side(e.g DN 9xxxx), 9 is stripped by route-pattern(pre-dot option 9.xxxx)(when using mgcp VG), however, the user can see all of numbers(including "9") by fixing code(CSCud08735). So the user is able to place a call by selecting the previous number from the call history. However, if the customer places a call by "Redial" Softkey instead of selecting the previous number from CallHistory, a new number(created by "Redial" Softkey) is displayed with pre-doted number again.
Conditions: using "Redial" key
Workaround: none

9971/9951 should clearly say when power-related issues are experienced, Open CSCtj72507

Symptom: Currently when the 99XX phones fail the power negotiation with a PoE device when adding new hardware accessories such as the USB camera, the phone currently doesn't display a clear error message describing the problem. You can only find out by looking at the phone debugs: 1. ssh to the IP Phone 2. Login to the phone 3. Run /usr/sbin/sdump -t 4. Review the logs. It could show something like this: 7417 NOT 18:10:21.008834 PWRMAN-eventPwrNeg(): curReq.valid: 1 info->curPwr: 11700 curReq.newPwr: 13500 7418 WRN 18:10:21.008926 PWRMAN-eventPwrNeg(): power neg failed: TIMEOUT 7419 NOT 18:10:21.063069 DMAN(1458)-isPowerAvailable(): Response from PM: NO POWER 7420 WRN 18:10:21.063400 DMAN(1458)-handleNewDevice(): Power Required is not available so rejecting device. 7421 NOT 18:10:21.063665 DMAN(1458)-parseAndHandleUdevMsg(): handleNewDevice returned Error: 128 disabling device ... 7492 NOT 18:12:11.786161 CDP-In Cfg_Idle_EvCdpDone_XIdle--CDP is Disabled and LLDP inhibited...wait for LLDP or 5 seconds 7493 NOT 18:12:11.935593 PWRMAN-eventPwrNeg(): curReq.valid: 1 info->curPwr: 11700 curReq.newPwr: 13500 7494 WRN 18:12:11.935685 PWRMAN-eventPwrNeg(): power neg failed: TIMEOUT 7495 NOT 18:12:16.787817 CDP-configSelectVLAN(): 0 OP_USE_ADMIN_DFLT:5 oper:4096 cdp:4096 lldp:4096 admin:4096 mac:0:0:0:0:0:0 7496 WRN 18:12:16.789123 CDP-cdpSetCos(): port 1, trust = 1, cos = 0 7497 NOT 18:12:31.938891 PWRMAN-eventPwrNeg(): curReq.valid: 1 info->curPwr: 11700 curReq.newPwr: 13500 7498 WRN 18:12:31.938978 PWRMAN-eventPwrNeg(): power neg failed: TIMEOUT
Conditions: Above trace is seen when a switch is used without proper PoE support (using PoE injectors) and not running CDP/LLDP.
Workaround: Use a powerbrick to overcome the power negotiation issue, or use a switch which properly supports power renegotiation through CDP or LLDP. Note: Firmware 9.0(1) only supports power renegotiating via CDP. 9.0(3) and above supports both CDP and LLDP.

Because this connection carries only voice traffic, the switch port should belong to a single VLAN. This means that you must configure a voice VLAN for the phone to function properly. You cannot configure voice and data VLANs on the same switch port.
