    Are you sure that your HEX value is correct? The three 0's at the beginning don't look right...

    Waht did you choose for "Scope" in your DHCP option? Global or server?

    Hi

    I use mitel DHCP helper to creat the value

    and for scope I use global

    I would try taking the ASCII value from the mitel helper and convert that to hex with an online ASCII to hex tool. That hex doesn't decode correctly to an ascii value.
