Solved: Any Poly VVX/CCX phones that support more than 2 DNS servers... - HP Support Community

jeff_h_ · ‎09-08-2025

Just wondering if I'm reading all the support/knowlege articles correctly that all Poly VVX or CCX model phones only support having 2 DNS servers configured (primary and alternate)?

If the DHCP server list is provided through a DHCP scope that has more than 2 listed, assuming the Poly phone will only use the first 2?

Noticed that some other Poly devices (RealPresence?) can support 4, but doesn't appear to extend to the VVX/CCX phones and just wanted to validate that. Thanks.

Hello @jeff_h_ , Welcome to the HP Poly Support Community.

Thanks for reaching out about your query regarding the Poly device.

I understand you're looking to confirm whether the VVX and CCX devices support only two DNS servers. You're absolutely right—the VVX and CCX series are designed to support up to two DNS entries: one primary DNS server and one secondary (fallback) DNS server.

Take care and have an amazing day!

Hello @jeff_h_ ,

Welcome to the HP Poly community.

Whilst the HP Poly Phones like the VVX, CCX or Edge E can read the DHCP Server information:

000101.374|dhcpc|3|00|dhcListener: Read succeeds: eth0 option: domain-name-servers 192.168.1.1 8.8.8.8 192.168.0.1

The DNS Server part only uses two:

000128.702|cfg  |*|00|RT|   DNS server is 192.168.1.1.
000128.702|cfg  |*|00|RT|   DNS alternate server is 8.8.8.8.
000128.702|cfg  |*|00|RT|   DNS domain is sbaiernewhome.lab.
000128.702|cfg  |*|00|RT|   Time server is 192.168.1.1.
000128.703|dns  |*|00|DNS resolver servers are '192.168.1.1' '8.8.8.8'
000128.703|dns  |*|00|DNS resolver search domain is 'sbaiernewhome.lab'

If no other volunteers reply, I suggest you contact our Support organization in your region. Details are in my Signature.

Best Regards

Steffen Baier

Thanks all for the replies and confirmation they currently only support 2 DNS servers 🙂
