Unable to get Poly CCX 700 to Provision to Lens via DHCP Auto Discovery

[SavageSage]

Hi Everyone,

I'm fairly new to Poly phones. I've spent most of my career working with Cisco, so forgive me if I'm missing anything obvious to the rest of you.

I'm following this documentation: https://info.lens.poly.com/docs/onboard/provisioning-phones#onboard-devices-via-the-provisioning-via...

I've got a CCX 700 and I'm testing with DHCP Options to provision phones to Poly Lens, but I'm not getting successful results.

• I can manually configure the provisioning server details and when I do the phone downloads it's config and works perfectly fine. But I need to make sure I can do this via DHCP auto discovery for an upcoming implementation.

• I've configured DHCP Options 66, 160, and 161 in my home lab (running my DHCP server via PFSense)

  • screenshot below

  • String Value: "https://[username]:[password]@[accountnumber].deviceprovisioning.dm.lens.poly.com"

• The phone appears to receive this - The logs show it is attempting to reach out but provisioning server settings do not show the information.

• The phone never provisions to Poly Lens and never receives it's configuration. So while it shows it is attempting to reach out, it never goes beyond that.

Am I missing something obvious? I've confirmed 1000x that I'm not mistyping anything. And I find it odd that it isn't entering the information into the provisioning server configurations. Even if I export the configurations, it's not there. Yet the logs show it is attempting to configure and failing. So I'm not sure what is going on.

Phone Information

• Phone Model CCX 700
• Part Number 3111-49740-001 Rev:B
• Software Version 8.1.2.1244
  
  

I was able to get a packet capture from PFSense to confirm the DHCP Option delivery:

Hello  @SavageSage ,

welcome to the HP Poly community.

Using DHCP options would not populate the Provisioning settings as this usually only shows manually set details. Same for the IP as an example.

Our FAQ holds this post:

The 3rd post in the above FAQ covers DHCP Provisioning and also has logging examples. Simply set these and check your logs after and/or post them here for us volunteers to check.

!!!! Solved !!!!!

In the phone logs, I noticed these first two lines:

0807161749|cfg  |4|00|Prov|CfgDhcpInformControl::ExtractOptions: DHCP ACK message failed initial validation. Skipping parsing of DHCP options.

0807161753|cfg  |4|00|Prov|CfgDhcpInformControl::ExtractOptions: DHCP ACK message failed initial validation. Skipping parsing of DHCP options.

0807161755|cfg  |4|00|Prov|Download of master configuration file failed

I explored this a bit and discovered that because there was a % symbol in my password, the phone was unable to parse the URL in the DHCP option it was receiving properly.  So while it was showing the provisioning server URL and username in the logs, the password wasn't parsing properly and was therefore failing to connect.

So I changed my Poly Lens password to remove symbols and updated my DHCP Option 66/160 URL and tried again, and it worked.
