Video Phone: 9951 Need a knob to disable DF bit, Open CSCtq90715

Symptom: Need an option to be able to set the DF bit to 0 on the fourth-gen-phones 9951.
Conditions: This was first identified on a fourth-gen-phone 9951 running 9-1-1 SR1 connecting to an ASA using anyconnect VPN.
Workaround: If the packets are too large use a layer 3 device in the path to clear the DF bit or ignore the DF bit so, the packets can be fragmented as needed.
Further Problem Description: 9951 phone may send large packets (1440 bytes) with the DF bit set to 1 and the MTU set to 1290. The ASA is unable to fragment these packets due to the DF bit set to 1. More over the max value for svc mtu on the ASA is 1406 bytes to allow for DTLS (max 94 bytes). Use the svc df-bit-ignore enable command on the ASA under group-policy associated with webvpn.

CMR records show null values for 6900 series phones, Fixed CSCtl12755

Symptom: CMR data is missing for 69xx Phones. CUCM does display CMR data for other phone models.
Conditions: 69xx phones are on 9.1.1 FW. Any FW prior to this release does not support CMR for 69xx phones. Network trace taken from 69xx phone show it is sending a K-Factor data, these are values used to populate CMR record.. However, the format of data is incorrect. CUCM does not read the data and populates CMR records with null values
Workaround: By upgrading the firmware version to the latest release cmterm-69xx-sccp/sip.9-2-1-sr1-uns.cop.sgn you may be able to fix this issue with CMR records.

CUCi config guide for display caller info to IE gives incorrect registry, Open CSCtx38237

Symptom: After configuring the 'Display Caller Information in Internet Explorer' for CUCiLync/Moc and testing it, the feature does not seem to work.
Conditions: CUCiLync/Moc and the 3 registry keys installed to either: HKEY_CURRENT_USER\Software\Cisco Systems, Inc.\Client Services Framework\AdminData or HKEY_CURRENT_USER\Software\Policies\Cisco Systems, Inc.\Client Services Framework\AdminData

6941/6921/6961 Ring Setting (Phone Active) doesn't work properly, Open CSCtx81179

Symptom:For IP phone 6941/6921/6961, whenever you go to the CM Web admin page select a phone, then select the line on the phone and scroll down to "Ring Setting (Phone Active)" selection and select Ring the phone won't respond like a 79XX phone. The phone should ring whenever a second call comes in, but it simply shows the call waiting information instead of actually ringing the phone as though it was onhook.
Conditions:Maximum Number of CallsRequired Field set to 4 Busy TriggerRequired Field set to 2 This occurs on firmware all the way up to 9-2-2-6 and CUCM System version: 8.6.2.20000-2
Workaround:No workaround known at this point.

Mapping of LDAP attributes to multiple CUPC fields breaks Add Contact, Fixed CSCsg17732

Symptom: The "Add Contact to Group..." menu is greyed out, for contacts that should be able to be added. or Right click the contact return by the search, and then click add contact to group, select the group, everything looks available but after click add, the contact is not added to the group, no error shown on the screen
Conditions: Mapping more than one CUPC field to the same LDAP attribute results in the attribute being assigned to only one field, in an implementation-dependent way. A recent change in the implementation has exposed this defect. Because the CUPS default is to map both "UserID" and "IM" to "uid", there is a high probability of trouble reports from this configuration. It also happened to customer who would like to map userID to telephoneNumber in callmanager and CUP, because CUPC field bussinessPhoneNumber is also mapped to telephoneNumber, so this bug is triggered.
Workaround: Remove the default mapping of "uid" to "IM". Do not map the LDAP attribute (e.g., "uid") which is assigned to "UserID" to any other CUPC field (such as "IM"). For scenario that userID is mapped to telephoneNumber, remove the mapping of businessPhonenumber to telephoneNumber, and change it to map to "ip phone" and then populate "ip phone" in AD for phone number
Further Problem Description: When checking in CUPC client detail log, the following error is shown: 2008-01-14 16:40:49,348 [0x120] INFO LCMiddleware - (MWMSG_EIM_LOOKUPCONTACTEMPTYNAME) EPASInterfaceManager::LookupContact() - alias name is empty 2008-01-14 16:41:15,516 [0x120] ERROR LCWIN32UI - (WINUI_ERROR_ADD_TO_CONTACTS_FAILED) Failed to Add Contacts from Search Results

Jabber for Mac should support the same attributes for photos as CUPC, Open CSCtw40214

Symptom: Photos are not displayed within Jabber for Mac because it can not pull them based on certain attributes. Jabber for Mac does not currently support the same attributes that CUPC does to pull photos from a web server.
Workaround: Use sAMAccountName as Jabber for Mac recognizes this attribute and will pull photos accordingly.

6945 phone can not handle "()" in corporate directory, Open CSCtx76044

Symptom: 6945 can not dial number via corporate directory when number contains "(" or ")", for example: +12 (345) 6789
Conditions: Occurs only when phone number contains "()"
Workaround: None

Cisco 792x doesn't honor URL encoding ISO-8851-1, Open CSCtx16478

Symptom: When web pages (xml service) is set to use ISO-8859-1 the "" object still uses UTF-8 when sending the query string.
Conditions: Using IP Phone Services
Workaround: Use UTF-8 (if possible, may not help in all cases if ISO-8859-1 is required).

DSCP settings can't be set in Vista OS the way they are in XP, Terminated CSCsl50789

Symptom: DSCP settings cant be set in Vista OS the way they are in XP
Conditions: None
Workaround: None.
Further Problem Description: Cisco Unified Personal Communicator sets DSCP settings using the Counterpath SDK to the custom values dictated by Cisco policy. While this works in XP, Vista changes the methods used to define DSCP parameters so the old methods no longer work (all DSCP settings default to 0). V Vista does allow setting some Windows defined defaults but these do not follow Cisco policy. To set custom values, you need to be an Administrator (or so it appears now). We are still investigating with Microsoft for an API level access to change the DSCP settings dynamically.

6941 / 6961 phones may freeze after many successive calls, Fixed CSCtw93646

Symptom: - Same symptoms as found in CSCtw45969 - The phone freezes in a ringing state. Going off hook gives no dial-tone, and only menu buttons respond.
Conditions: n/a
Workaround: n/a

6921 gets stuck due to memory allocation, Fixed CSCti43121

Symptom: 6921 gets stuck after several hours / days. Screen stays frozen, and time doesn't change anymore. A manual reset on the phone doesn't solve the problem, and the phone needs to be disconnected and reconnected.
Conditions: 6921 with firmware 8.5(3), 8.5(4), 9.0(2) and (3)
Workaround: Restart the phone by disconnecting it from the power source.

11n AP on UNII-1 doesn't demodulate ACKs from 7925G, Open CSCtx43105

Symptom: Intermittently, a 7925G phone may experience choppy audio, or lost audio.
Conditions: 7925G is associated to an Aironet 802.11n (1040, 1140, 1250, 1260, 3500) series access point, which is in the UNII-1 band (channels 36-48).
Workaround: Some or all of these may mitigate or eliminate the problem: 1. Move the access point to a UNII-2, UNII-2 Extended or UNII-3 channel. (This is the only known 100% workaround.) 2. Disable DTPC on the AP (e.g., on a WLC, uncheck the "DTPC enabled" box on the wireless network.) 3. Configure the 6Mbps data rate as the sole mandatory rate. 4. Replace the 11n APs with 11a/g APs.
Further Problem Description: Although the symptoms of this bug are identical to those of the bugs CSCta65070 (9971)/CSCtg04992(7925G), this bug is experienced even when the phone is running firmware with the CSCtg04992 fix. This bug is intended to provide fix on the phone side. Additionally, the bug CSCtt67979 has been filed to explore the feasibility of implementing a workaround on the access point side.

ALL-LANG:CIPC:UI: Olsen time zones not supported, only legacy time zones, Fixed CSCte84749

Symptom: Incorrect date/time is displayed on CIPC UI.
Conditions: Using non-legacy time zones (Olsen time zones) CIPC 7.0(x) connected to CUCM 8.0 or later
Workaround: Use Legacy time zones Please note that CIPC 7.0(x) is based on TNP phone load 8.3.5 and only supports the legacy time zones. Support for the non-legacy time zones (Olsen time zones) is in TNP phone load 9.0(2).

Custom status not reflected correctly on CUPC after Phone goes off DND, Open CSCtx63624

Symptom: CUPC status displays (RED - DND) CUSTOM STATUS in (Green - Available) Color
Conditions: Steps to Reproduce: -Manually Set "In a Meeting" (Created as Custom RED Status) -LOCK PC -UNLOCK PC -Go off DND from the Desk Phone Itself -Will notice CUPC changing the Jelly from RED (DND) to Green (Available), however the Custom Message still shows "In a Meeting" This only happens if the PC is locked an unlocked. If the PC is not locked this doesn't happen.

792x sends SCCP as UP0 when secure SCCP is used, Fixed CSCtx08144

Symptom: 792x sends SCCP as UP0 when secure SCCP (TCP port 2443) is used. If non-secure SCCP is used (TCP port 2000), then the 792x phone sends SCCP as UP4 as expected.
Conditions: Using the 792x phone with secure SCCP.
Workaround: Use non-secure SCCP.

Minimize RTP Delay from HW side when answering call on RT-Lite, Open CSCtd57345

Symptom: RTP delay happens when answering call on RT-Lite.
Conditions:
Workaround:
Further Problem Description: This is caused by HW limitation that charge/discharge noise would happen when answering call. And the expected delay from HW side would be 260 +/- 20 ms now. Currently to avoid any noise when picking up through speaker/softkey, the software value should be at least 280ms, which causes around 370~430ms RTP delay between MediaPathChange event and first sent RTP packet on the callee side. This is somewhat not consistent with our expectation. Need to find out the exact delay in HW, and check whether we can improve the performance.

CUPC should not write files with invalid characters for filesystem, Open CSCtt93768

Symptom: CUPC users cannot listen to voice messages when caller ID contains special characters.
Conditions: When CUPC downloads voice messages, it includes the caller ID as part of the file name. It is possible for caller ID's to contain characters such as *, ?, /, ect, which are not allowed to be part of a file name by the file system.
Workaround: Remove special characters from the caller ID before the call goes to the voice mail server.

Delay in starting RTP from 6941, Fixed CSCtc96381

Symptom: Calling from any other phone model to a 69xx, after going offhook on the 69xx it takes about 2 seconds before caller and called party can hear each other. This is in the same location where other phones they are working fine. Phone are connected to the same switch and vlan of the CUCM.
Conditions: So far reproduced on 6941/61, but applicable to all 69xx series.
Workaround: None
Further Problem Description: Two delays are noticed in the tests with the 6941. - It takes about 0.14 sec before the 6941 socket is ready to receive the incoming RTP packets sent from the other phone to the desired. This causes the 6941 to generate ICMP port unreachable packet until the socket is ready. - It takes about 0.67 seconds between the StartMediaTransmission and the 6941 first outgoing RTP packet, So there are about 0,81 seconds before 6941 is ready to listen and sending RTP packets. This is not an enormous time, but if user is very fast on picking up the handset this can be perceived. Tested in the lab, with a 7970 on speakers calling to a 6961. If the 6961 user goes off hock very fast and immediately start talking "one, two, three, four, five, ...", on the 7970 only starting from "two" or "three" can be heard, so the first words are missed.

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.

CME: 9971 does not negotiate H.264 Non-interleaved packetization mode, Open CSCtx87044

7925 sometimes takes 1+ second to respond to WPA M1 key message, Open CSCtt38270

Symptom: A wireless phone call may experience a voice gap of 1.5 - 2 seconds when it roams if using WPA2-PSK.
Conditions: 7925G is configured to use WPA2/AES PSK.
Workaround: Configure some key management method to avoid performing a full WPA2 key exchange at each roam time. For example, EAP with CCKM, or static WEP. If using PSK, then reducing the WPA key retransmission timeout (e.g., on a WLC, via "config advanced eap eapol-key-timeout 250", may ameliorate the problem somewhat (e.g. bring the outage duration down from 2.5 to 1.7 seconds.)
Further Problem Description: A wireless packet capture, or a "debug client" on the WLC, will show that the WLC/AP transmit the M1 key message to the phone (and the capture shows that the phone ACKs it), but the phone does not send its M2 key. So the WLC/AP have to retransmit the M1 key, till finally the phone responds.

Click to Call dll is causing problems to 'Business Objects' application., Open CSCtx42286

Symptom: Click to Call and a SAP Application called 'Business Objects' seem to use the same dll (log4cxx.dll) with Microsoft Office applications. The result is that BO add-in fails to load when Click to Call is enabled.
Conditions: Running CUPC 8.5.3 on the same client PC where BO application is also installed.
Workaround: Disable Click to Call add-in with the following Reg Key: For excel, modify the key value of LoadBehaviour from 3 (enable) to 1 (disable) HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Excel\Addins\Cisco.ClickToCall.Excel.Connect\ Likewise, for Powerpoint make the same change here HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Powerpoint\Addins\Cisco.ClickToCall.Powerpoint.Connect\

All Calls shows wrong session bubble for two shared lines in one phone, Fixed CSCtb78789

Symptom: AllCalls shows confusing session bubble for two shared lines in one phone
Conditions: A (admin) / B (boss) / C (boss) as an example. A's phone has a shared line with both B and C. So 3 lines total, and then All Calls filter as well. 1) B calls C. C does not answer (he's out golfing). 2) A answers the call on her phone. 3) A selects the 'All Calls' filter. At this point the session displayed in the All Calls filter says: C on B (CONNECTED) At this point we are following the current spec. An argument could be made that this is backwards for this scenario. It's saying that A is looking at a connected call with C on B's line, when in fact she is on a connected call with B on C's line. Description:
