CDP Driver Stops Working , Fixed CSCsu45473

Symptom: CDP Driver stops working on desktop. CUVA does not crash, but operating system reports error.
Conditions: CUVA 2.1.1.7 is not registered to any phone. The problem has been observed in Vista Enterprise and Vista Business.
Workaround: CUVA will still be fully functional as the CDP process crashes on exit when it does not need to be running.
Further Problem Description: CUVA can be used. There is anoying pop-up message that keeps on telling that CDP Driver Stopped working Details on the crash: The crash was happening on exit due to pending transaction(s) between the CDP driver and CDP driver user mode process (CDPDrv is the process name in Task Manager). The CDPdrv process will be stopped when there are no IP phones in the setup or an IP phone has been found and a CAST connection has already been made. The fix was to make sure there are no pending transactions and exit without crashing. It will not affect the application since the crash happens on CDP process exit when it does not need to be running.

Phone FW 8.5.2 enforces max MTU size 1500, causing interop issues , Fixed CSCta69051

Symptom: In load 8.5.2, we enforce max packet size is 1500, thus, the dot1x supplicant only reads up to 1478 byte payloads (22 bytes header). The changes were done as part of EAP-TLS feature. We see that the phone is truncating or blocking packets above it's MTU setting (1500), which is a new behavior in this load - dev team confirmed that we did not enforce MTU in earlier loads. This is causing a lot of interoperability issues with the PCs behind the phone trying to use dot1x or 802.1x EAP-TLS as there also seems to be an issue with PCs fragmentation of packets with certificate.
Conditions: Phone load 8.5.2, PC attached to the back of the phone using EAP-TLS Authentication.
Workaround: - If possible, limiting the packets sent by the phone to MTU <1500 - using the older FW version

ATA186 Auto-Registration Fails if XMLDefault file exceeds 4k in Size , Fixed CSCsd44357

Symptom: ATA fails auto-registration on freshly installed Seadragon-CM.
Conditions: CM's XMLDefault.cnf.sml size (found in CM's tftp directory) exceeds the 4k byte max.
Workaround: Use Manual Registration instead. Solution: Increase TFTP buffer size from 4k to 10k. Availability of Fix: Fix will be available on all ATA/SCCP CCO-released softwared dated 2/21/06 and beyond.

Workaround: None.
Further Problem Description:

New & RMA 7921 Load cannot be downloaded from 1.3.3 , Open CSCtc85005

Symptom: Unable to downgrade load from 1.3.3 to anything older.
Conditions: 01. New or RMA 7921 02. App Load ID: CP7921G-MFG-D.5.LOADS
Workaround: None At the moment
Further Problem Description: Found that all D.3/D.4/D.5 builds have downgrade restriction : So inorder to successfully upgrade the firmware on such phones we need to install the 1.3.3 firmware. MFG-D.3 is equivalent to engineering build 1.3.2.6. 1.3(3)is equivalent to 1.3.2.8/MFG-D.4. Conrad Price - PM : 1. The Original memory manufacturer for the 7921 phones has gone out of business and the RMAd 7921's that you are receiving are new with new memory from a new manufacturer. 2. The RMAd 7921s had to have the memory and firmware qualified with the new manufacturer and it is locked to a minimum version of 1.3.3. 3. If an older 7921 is upgraded to the 1.3.3 firmware, the phone will not be allowed to be downgraded to a lower firmware - this is true and is open for discussion So these phones, with the CP7921G-MFG-D.5.LOADS firmware, will never be able to downgrade to any existing version of firmware before v1.3.3.

7925 with voice gaps with inbound/outbound PSTN calls , Fixed CSCtc54410

69xx ignore StopToneMessage ignored with Outside Dial Tone , Fixed CSCtd22034

Symptom: In a call which provides outside dial tone, if user they quickly press the first 2 digits of the route pattern, then he keep on hearing the outside dial tone for the whole call.
Conditions: 69xx phones dialing a pattern which provide outside dial tone
Workaround: None
Further Problem Description: It seems the phone in some conditions ignores the StopToneMessage sent after the StartToneMessage OutsideDialTone. Therefore the phone will keep playing this tone until a StartToneMessage AlertingTone is received. If it's not received, user will keep on listening the outside dial tone for the whole call. This is a firmware issue, signaling from CUCM is fine

7970 8.4.2 color scheme change causes CLID to blurr , Open CSCsw96960

Symptom: 7970 CLID display blurr's over 3 feet distance on 8.4.2 load. Reason being there was a change in the background color from white to dark blue for CLID display in 8.4.2 load. White being a contrast color to the black font for CLID was good with any viewing angle.
Conditions: 1) The viewing angle of phone. (LCD being inline with your eye). 2) Phone rested on its stand at any position.
Workaround: Changing the viewing angle might help .Under Settings -> User> Preferences -> Viewing Angle to see if it improves the appearance
Further Problem Description: User lighting environment may contribute to the problem and hence changing view angle on the phone might not be the a workaround in such a scenario.

Upgrade Status shows Running until new login screen shows due to timeout , Fixed CSCsl91207

Symptom: Sometimes, the upgrade from 1.2.5 to 1.2.6 GUI upgrade status displays Running instead of Complete.
Conditions: Specially at the end of upgrade log shows some message such as /user/local/platform/script/2.0.0.1-1/platform_migration.sh: : INFO:/partB/usr/........./enConfigration.xml does not exist Migration not required. chown: failed to get attributes of '/usr/......./CCMencryption.jar': No such file or directory /usr/local/snr/.....ccmmssnr_post.sh: : Copying informix ... Could not access INFORMIXDIR /opt/informix/database/current. Those message will mislead user that the upgrade doesn't complete. Finally around 30 minutes after the completion of the upgrade, the installation screen is gone and the new login screen shows up for the login due to the idle timeout. Sometimes after 30 minutes after the completion of the upgrade, the installation screen still exists and no new login screen shows up.
Workaround: Go to platform console to check whether the new version shows up on the console. Or select automatically reboot after the completion of the upgrade during the upgrade configuration selection.

Delay in starting RTP from 6941 , Open 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.

7936 CME: would not initiate MeetMe conference , Terminated CSCsy19695

Symptom: 7936 would not initiate meetme hardware conference

Workaround: there is no workaround

DPA sends CalledPartyNumber instead of OriginalCalledPartyNumber to VM , Fixed CSCsg21994

Symptom: Calls routed to voicemail via DPA will show up in Octel destined to the wrong voicemailbox. This can result in the caller being prompted to login or simply getting the default greeting.
Conditions: DPA voicemail integration with CM 4.2(1) or later (including CM 5.0).
Workaround: None
Further Problem Description: In previous versions of CallManager the SCCP CallInfo message sent to a phone had the originalCalledParty and calledPartyNumbers with the same value (that of the originalCalledParty number). This was done to be backwards compatible with old voicemail products such as UOne. Since this message is only used to present display information to the SCCP device it did not impact the routing of calls. CSCsb57445 was filed to fix this issue and get the calledPartyNumber to display the correct value. This fix had the side-effect of causing the wrong number to be sent by the DPA as the called party number.
