Hello, after changing subnet mask and setup new server DHCP the mitel 5312 units displaying Option 128 missing.

If appears the handsets can't find the new DHCP. Any ideas on how to get the handsets to find new DHCP to get IP?

Thanks in adavance - Joe

Try defaulting the phones then let them reboot

I suppose you're entitled to your opinion, I'm just not going to suppose very hard.
