fix zero-touch provisioning of desk phones


How can I fix zero-touch provisioning on our hundreds of new-in-box vvx250 polycom phones?


Some auto-provision on first boot, as advertised.

Some fail and must be factory reset.  After the factory reset some will auto-provision correctly.

Many require assisted provisioning.  This requires us to log into the phone's web page and manually enter the provisioning URL, clear out the username/pass, and set DHCP to static.


My goal is to avoid assisted provisioning.  Is there a way to take the config of a phone and quickly flash it to another phone?  Can we do that in bulk?

@JoshT , 


Good day!  I hope you are well. 


As you indicated, Zero Touch Provisioning (ZTP) will be the best way to provisioning all of your Poly handsets.  

I would recommend opening a support ticket on one or two of the handsets that are failing the ZTP process which is requiring you to step through the assisted provisioning process.  It would be best to make sure the root cause of the issue is understood. 


There may be another viable option for you if all of your devices share the same manufacturer and if you have control of the DHCP server. 


Zoom has a single URL per manufacturer which would eliminate the need for the assisted provisioning and bypass the ZTP process that appears to be failing for you. 


The URLs are as follows: 

AudioCodes -

Poly -

Yealink -

This info was pulled from here:


Keep in mind, using one of the above URLs is only supported by the corresponding manufacturer, which is why it would be best to ensure ZTP is working properly.  Not all devices are supported with this method, though the VVX-250 certainly should be. 


If you have a ticket, feel free to direct message me with the number and I'll see if I can assist. 


Does Zoom have any document explaining how to configure DHCP options for Poly VVX-series phones to force registration to ?

hi josh


one of my clients had a similar issues.


for ztp, poly phones need to connect to poly.   check that the phones have access whatever subnet they may on.  in one case ztp at one location worked but not at another.   the issue was solved with a change to access control list.

Required Ports and Trusted IP Addresses and Hosts ( 


in real time, zoom connects to poly to provide the mac addresses that a zoom phone admin enters.  the mac addresses are hex addresses containing 0-9 and a-f.  you should not do a copy and paste of the mac because what you copy may contain special characters.  you should manually enter the mac addresses.
