VVX Phoen DHCP NTP Option 4 or 42

I am trying to setup our DHCP server with the correct options and have run into an issue with the VVX 250 and VVX450 phone not applying the NTP option from the DHCP server. I have both option 4 and option 42 set.

Option 4 is Time Server

Option 42 are NTP Servers

The only non standard DHCP option set is 144 for VLAN assignment.

 

I searched the KB but only found one reference.

KB Article 11393 

This article states that it is not supported because "No, There is a standard DHCP option for this purpose." 

 

Options 4 and 42 are part of the RFC-2132 standard Option 42 is in section 8.3 (1997)

 

I also found this admin guide vvx-obi-admin-6-4-1 that shows option 42 is supported.

 

What do I need to do to get NTP configured on DHCP server recognized by the VVX phone?

 

thank you for your time.

Hello @Paul Roy ,

Your post ended up in the Spam Filter so I moved this here.

As Poly offers the UC Software or Obi Edition it would be of interest to which software and version of this you are running on the VVX as this helps us answer your question.

 

Best regards

Hello @Paul Roy ,

 

The phone is running the "normal" UC Software.

 

Simply pressing 1,4 and 7 for two seconds should show you the most important information.

 

UC Software supports the DHCP option 4 or 42 or both and I have this setup in my own lab.

 

I suggest you check this:
