Polycom DHCP Options VVX600 and Infoblox option 66 or 161 Not working?

Polycom Community,
                     Recently we have been manually configuring our polycom VVX600s and pointing them to our provisioning server. We are using Infoblox as our DHCP Server and putting in 


Option 66/161/160 ftp://pftp:Randompassword1234@ of FTP Server) the phones aren't seeing this


We have option 42 for our time server configured as our DC for time and the phones still don't have the correct time. 


 Option 3 we have the web server FQDN configured as the web internal fqdn but as hex


Option 120 is our SBA converted into hexadecimal


Option 4 web server port 443 converted


Option 5 /certprov/certprovisioningservice.svc converted to hex


Even after all of these configurations the phones aren't seeing the options. We have checked the firewall to make sure its not blocking FTP but that's not the case. The phones aren't even seeing the options. We have also checked inside of the phone in the web gui to see what option it's reading. We have moved and changed the options in the phones to see if they can read 161, 160, or 66 and none have seemed to work. Not sure what could be causing this. We have also each once checked the options over and have cleared and reboot the phones. When we manually provision the phones they reach the FTP server no problem.

Hello mekadaniels,

welcome to the Polycom Community.

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

Please also include if you are using a SIP server or a LYNC / Skype for Business server.

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 "Read First"

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


Use a spanned / mirrored port and use this:

Yes we were able to get this set up for us. We had the options put in infoblox but the Voice VLAN wasn't set up properly. Also checking if the ports are configured properly as well. - Meka
