VVX config sync loop when user moved to SFB 2019

Hi All,


I have a strange issue whereby if i move a user to Skype for Business 2019 on premise and sign them into a phone VVX 310 (same issue on a VVX 200 or 410). The device no longer respects the polling interval and starts polling every second. It seems to now poll the configuration server at intervals of 1 second and then 8 second.


It pulls down the config and applies it successfully (the phone reports no errors).



Phone Model  VVX 310
Part Number3111-46161-001 Rev:A
UC Software Version
Updater Version

I am using the following polling settings;


<prov prov.polling.enabled="1" prov.polling.mode="random" prov.polling.period="86400" prov.polling.time="01:00" prov.polling.timeRandomEnd="05:00" />


For some reasons when the user is Skype for Business 2015 homed it respects the settings and only polls early in the morning. If i move the user to 2019 it basically loops polling the config 1-10 seconds.

Does any one know what debug log i need to enable to see why it wants to poll so aggressively?


Attached is the debug log i have.


Any help as to debugging this would be greatly appreciated.

Hello @dappleby ,


Welcome back to the Poly Community.

UC Software 5.9.0 is no longer a Poly supported software. You should be using UC Software 5.9.5 instead.


In addition, Skype for Business can force settings on the Phone. You should be able to see this in your backup in the <call_server section.


I suggest you check this FAQ article:


Feb 02, 2016 Question: How can I prevent a Poly Phone to be downgraded/upgraded automatically via Skype for Business and/or Office365?

Resolution: For Skype for Busines please download, unpack and import the attached LyncProvisionDeviceParams. For Skype for Business Online / O365 in addition please set the EnableDeviceUpdate to false as explained => here <=


The next step would be a support ticket.


In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

End Customers are usually unable to open a ticket directly with Poly support.

I can see this phone was sold via GECDF-Exclusive Networks Pty Ltd back in 05/02/2016.

As the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Thanks Steffen,


Adding these options fixed the issue for me ;

device.set="1" device.prov.lyncDeviceUpdateEnabled.set="1" device.prov.lyncDeviceUpdateEnabled="0" lync.provisionDeviceParams.enabled="0"
