Hello @sub0 ,
welcome to the Polycom Community.
Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.
This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
As a reminder the basic information asked for:
UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.
Since UC Software 5.9.0 simply provide this via the Web Interface Diagnostics > Download Support Information Package
Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used. In addition providing all details at the same time allow us to check logs or look up a potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.
Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up post’s.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

This seems counter intuitive, but you need to assert provisioning from provisioning, instead of relying on option 160. What I have chosen to do with our provisioning is force the DHCP boot server option to static and specifically SET the provisioning server data from provisioning. This ensures that once the phone has talked to my provisioning it will not listen to erroneous option 66/160 handed out by some misconfigured gateways.
See these options:
<device device.set="1" device.dhcp.bootSrvUseOpt.set="1" device.dhcp.bootSrvUseOpt="Static" device.dhcp.bootSrvOptType.set="1" device.dhcp.bootSrvOptType="String" device.prov.serverType.set="1" device.prov.serverType="HTTP" device.prov.serverName.set="1" device.prov.serverName="HOST.OR.IP" device.prov.tagSerialNo.set="1" device.prov.tagSerialNo="1"/>
