Hi Guys,
I have spent 4 hours with Cisco TAC yesterday and they could not resolve my many issues, software related issues.
Here is the summary, my original UC520 had a fatal CPU bus crash which corrupted the CUE module and both flash cards became corrupt...
Cisco TAC replaced my device with a new UC520.... I have been trying for 1 week now to reload this device back to the config and level I had before but ran into so much issues which I never ever experienced before on my other unit.
I was trying to use cca 2.1.1 with 7.1.3 EA pack which I have tried several time but the CCA always seems to find some issue or other... However I manged once to get it to work dont know how but it did.
once software was upgraded I ran the telephone wizard and completed as I should... Only 1 change was the data vlan which I changed to 10.54.8.* from the 192.168.10.1... everything else was left default i.e next, next, next finish....
Thus U get prompted it is about to write the config.....It takes some timw only for it to have only hlf programmed or written the config file... The IP phone aint programmed voicemail isnt active etc... On logging into the CUE via the web site i get prompted it has not been intialized and that it needs to be setup... on my old box never needed to do this... So this was strange... However Cisco TAC got that part working only for another 4 issues to develop such as internal callls from ext to ext work, howver calls external dont even reach the voicemail... Cisco spent 2 hours last night debugging and debugging for no result....
I use the Skystone software which acts as the interface between the UC520 and Skype.... We performed several tests last night imediate call forwards to 299 and then different timouts for 100% no voicemail activation and what seems to happen is that when the cisco vmail should kick skype is acting if the call is rejected and the skype vmail kicks in all the time instead of unity....
Even when I got that part working on my old system dotn know how but it worked a treat, when a user left a vmail the dtmf was not being heard by the unity so if after you left the message and wanted to mark it urgent it would not here the tones and nothing happens.... Thus my concern is when I set up the IVR using the same infrasructure I fear that it will not work as the tones are not being heard.... SkyStone uses the SIP thing......and thats how the uc520 acts with skype using SIP....
As of now I have logged into the CUE and factory reset it, I have erased all nvram, flash cards all is wiped....
What version of the UC520 software packs should I use, which one is the most trusted and stable that will give me the same features as the latest early adopter packs....
Have I missed a major step to cuase such issues, or changing the data vlan to a new IP is this causing a major issue cause as I look at the running config after CCA has completed it in the acl lists there are a number of refences to the the old defualt data vlan IP and I am now wondering if this is causing me all my sore heads.....and thats not after a few a glases of wine after being on the phone with cisco for 4 hours....
Can anyone shed light on my tech downfall?
Many Thanks in advance....

I have loaded the 7.1.3 early adopter pack on a UC520 unit out in the field, and I have not had problems with that release once I had the UC520 unit configured correctly. The customer that was using this release was using SIP for external calls, and was not using FXO, FXS, BRI, or PRI T-1s. The codecs being used with this configuration are G.729 (without Annex B), G.711 mu-law, and G.711 A-law. Configuring G.729 with Annex B can cause problems if your SIP provider does not support it.
I have never had any of our UC520 units nor their CUE modules fail in the field. The CUE versions that we have used out in the field, and that have been included in UC500 software packs, 3.0.3, 3.2.1, and 7.0.3, have been stable. We had customers early on that reported that the voicemail would get cut off after approximately 25-30 seconds. I know that this problem exists in CUE 3.0.3 and 3.2.1, but I am not sure whether the problem is there in CUE 7. The fix to that problem is to add the voice-class source interface Loopback0 to the dial peers for VM and auto attendant if you are using a UC520 or UC540.
Example CUE dial-peer configuration for UC520 or UC540:
dial-peer voice 2000 voip
description ** CUE Voicemail pilot number **
destination-pattern 299
b2bua
voice-class source interface Loopback0
session protocol sipv2
session target ipv4:10.1.10.1
dtmf-relay sip-notify
codec g711ulaw
no vad
Here are the important settings that need to be set for CUE dial peers:
Here is the part of the configuration where the codecs used for calls to and from SIP providers is configured, in order from the most preferred codec to the least preferred codec):
voice class codec 1
codec preference 1 g729r8
codec preference 2 g711ulaw
codec preference 3 g711alaw
Here, I have the G.729 (without Annex B), G.711 mu-law, and G.711 a-law codecs listed. You should not have the G.729 with Annex B codec in this list if your SIP provider does not support it as it can cause calls to fail. If your SIP provider supports iLBC or G.722, you can add them to the codecs for negotiation.
You should have at least one of the following codecs in the codec preference list:
You can have these codecs in the codec preference list:
Here is the part of the configuration that is used for transcoding. Transcoding is very important for several reasons:
Here is the part of the configuration that enables transcoding:
!
voice-card 0
dspfarm
dsp services dspfarm
!
sccp local Loopback0
sccp ccm 10.2.24.1 identifier 1 version 4.1
sccp
!
sccp ccm group 1
associate ccm 1 priority 1
associate profile 3 register mtp123412341234
!
dspfarm profile 3 transcode universal
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
codec g729r8
codec g729br8
codec ilbc
codec g722-64
maximum sessions 2
associate application SCCP
!
telephony-service
sdspfarm units 3
sdspfarm transcode sessions 8
sdspfarm unregister force
sdspfarm tag 1 confprof1
sdspfarm tag 3 mtp123412341234
In the example above, the transcoding DSP farm profile is marked as an universal transcoding profile. Universal transcoding enables you to transcode between any of the codecs in the list, and is not limited to G.729 to G.711 transcoding. You must specify universal in the dspfarm profile line if you have iLBC or G.722 in the codec list. The transcoding codec list needs to include g711ulaw, g711alaw, g729ar8, and g729abr8. If you enabled G.722, g722-64 must be included as a codec in the transcoding profile. If you enabled iLBC, ilbc must be included as a codec in the transcoding profile.

How did you upgrade your UC520 to 7.1.3? I was able to successfully load the 7.1.3 release on a UC520 unit. Did you use CCA to perform the upgrade?
I have deployed a refurbished UC520 a few weeks ago, and when I received the UC520 unit, I actually upgraded it from 4.2.7 to the 7.1.3 release. I also did get CUE upgraded successfully to 7.0.3. Here is what I did to upgrade the UC520 to 7.1.3:
Format of FTP URL for the IOS copy and IOS archive tar /xtract commands:
ftp://
with
Format of FTP URL for the CUE software install clean command:

Format of the IOS copy command:

Format of the IOS archive tar /xtract command:

I have had customers report problems with the 7.0.x and 7.1.x software packs. Most of the problems resulted from incorrect configurations on UC520 units, and I was able to get these problems fixed by making the appropriate adjustments to the UC520 configuration.
I actually have not had problems with 7.1.3 after I got the UC520 correctly configured. I know that the 8.0.0 software pack for the UC520 has been released, but I do not know how stable the 8.0.0 release is.
Could you please send me the following:
These details will help me see that everything is correctly installed and check for any problems in the UC520 configuration.

Did you upgrade to CCA 2.2 yet? CCA 2.2 has already been released.

Hi,
After spending my whole weekend, I entually reinstalled Java and CCA 2.2 on my laptop runnign windows 7. I wiped the UC520 copied the factory config file and the IOS file that was in the UC8.0.0.zip file and with patience I managed to get everything back up and running....
Happy Days... However I am trying to work out what files I require to change the region and voicemail to GB.
Thanks

I replied on your other thread with the following:
Go to www.cisco.com/go/uc500swpk and download the files cue-vm-en_GB-langpack.ise.7.0.3.prt1 and CME-locale-en_UK-English-7.0.1.1.tar. There are instructions on how to apply the updates at https://supportforums.cisco.com/docs/DOC-9692. This doc is a little old since it is based on CCA 1.9, but it is still fundamentally correct. The main difference is that the Region tab used for changing the phone locale has relocated to Configure > Telephony > Region.
Cheers,
Dave.
