Cisco 7937G Keeps Rebooting on a UC540 8.6.1

Hi,

I am having a problem with a Cisco 7937 on a UC540 with an 8.6.1 software pack. Basically, the phone never registers and keeps rebooting all the time.

I think this is the same issue as in these two threads:

https://supportforums.cisco.com/thread/2133569

https://supportforums.cisco.com/thread/2066219

The phone firmware is 1-4-4-0. User and Network locale are both set to US.

I have tried the suggested in the above threads, but no joy.

Any ideas?

Thanks,

David

Hello David,

This is a known issue. Please upgrade CCA to 3.2.3 and the software pack to 8.6.2

CCA 3.2.3 Highlights:

CSCue46560: 7937 conference phone reloads when locale configured in CCA

Thanks,

Hi John,

Thank you so much for pointing that out. I am wondering how would I be able to implement the workaround (got that from the bugtool) which states the following:

---------------------------------

Workaround:


The workaround is to enter a tftp server entry for the sccp file used.

UC540(config)#tftp-server flash:/its/user_define_4_rp-sccp.jar

---------------------------------

What would be the 'user_define' in my tftp statement if I am using US as a default for both. When I do TFTP packet and event debugging I can see that the phone does actually download a sccp jar file. I am quite confused.

I am keen on the workaround as I won't be able to reinstall the box with the new software as it is in production and the customer is a bit angry already

Thanks,,

Dave

Hello David,

In the TFTP event debug do you see the phone request and download that file?

Can you send me the output of show flash, so I can see what files you have on the flash?

Thanks,

Hi John,

I actually came back to the office for this one.

I uploaded the debug and the show flash to my original post. Have a look, although I saw something new I did not see the previous time I looked at the debugs - there is a TFTP request for something that starts with "United_States/g3-tones.xml" rather than "English_United_States...". Maybe this is the bug, that I did not see before...

Thanks,

David

Hello David,

Please add the following to the configuration in CLI:

tftp-server flash:/English_United_States/g3-tones.xml alias United_States/g3-tones.xml

Thanks,

-john

Hi John,

I did try that immediately after my last post - the result was that the file transfer was successful (for that exact file) but then it rebooted again. Also tried a factory reset and the same again.

Thanks for your input so far, mate!

David

Hello David,

Can you post the following:

ephone config

ephone template config

telephony-service config

Thanks,

-john

Hi John,

I have uploaded the config. All this was done through CCA 3.2.2. I have tried my best so far not to make any changes on the CLI...

Thanks,

David

I actually removed this file from the tftp with:

no tftp-server flash:/English_United_States/rp-sccp.jar alias English_United_States/rp-sccp.jar

And the phone registers fine. Must be a problem with this JAR file?!

Hello David,

It is not  problem with the jar file but with the alias.

You have fixed it actually.

Best regards,

Alex

Hi Alex,

We have similar issue "phone is rebooting continuously". We are using CME.

Version 8.6

Phone : SEP0004F2F7870E firmware is latest one.

Do i also need to remove the Jar file ?

I have attached the logs.

Thank you very much David Zhivkov for sharing this workarround

It was exactly the same "user_define_4" for me to solve my problem.

 

But if you need to know the full path of your "user_define" just type 'show flash' comand

to see every file that have been uploaded into your flash; then you can include the rp-sccp.jar file into the tftp-server that is needed to boot your 7937G conference station.
