Factory Reset Phones via DHCP Options

I was looking for a way to use dhcp options to force a factory reset on phones.  Would like to set up one or two ports on a switch that I can plug phones into and they would pull a special 000000000.cfg file that would force the phone to reset.  Has anyone tried this or have any suggestions?


Thanks in advance!

welcome to the Polycom Community.

It is always useful to include the currently used SIP or UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


To answer your question to my knowledge this is not possible.


Just use an MCK ana multiple key combination as outlined here:
