How to stop phones from downgrading?

Running Skype in a hosted 3rd party environment.  Have no control over the Skype server.

 

Run my own provisioning server.

 

Example, the latest 5.6.0 software.  I put the sip.ver and 3111-48600-001.sip.ld files in the root of the FTP server.

 

Use the basic default config files, I just add one config file for customizations, otherwise it is stock.

 

Phone takes the update upon reboot.  Great.

 

But then immediately it prompts that there is an update available.  And you select that, and it shows the past version.  Red ! mark.  You reboot the phone it keeps prompting, and it keeps downgrading.

 

Reboot the phone again, it upgrades.  After that, it wants to downgrade??  Around and around we go!!!  The old firmware isn't even on my server anymore.

 

How do you stop this madness???  Why does it do this?  How are you supposed to upgrade your phones to the latest version if it keeps wanting to prompt users to downgrade?  Maybe missing something?  I run all VVX 601 and a few VVX 501, so they use the same firmware, and both exhibit the same behavior.  They are about to kill me!!  And all are getting annoyed.

 

Thanks

Re: How to stop phones from downgrading?

As the other thread has shown and another user stated, this doesn't work.

 

The only way I found last night to stop this was to create a new subfolder Firmware_5_6 for example under the FTP root.  Then, put the minimal firmware files and sip.ver under there.  Point the 000000000.cfg file for the App sip.ld location to that subfolder.

 

Only then did the phones upgrade to the newest version and stop asking.

 

Also removed all .ld files and .ver files from the root of the FTP.

Hello techlogik,

If this does not work please escalate this into support.


In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you. End Customers are usually unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.
