Yealink T42G and T46G VLAN DHCP

Hi,

I have found a issue where the phones are not getting the provisioning server from the DHCP server.

All previous Yealinks gain their DHCP network settings and the provisioning server once connected to our VLAN.

But I have noticed the Yealink T42G and T46G do not.

Has anyone tried this, or has a resolution for this.

I can't seem to find a firmware update to test either. =(

Regards,
